Why Your CNC Router Randomly Stops In Middle Of Projects [You'll Get It] - Garrett Fromme
Вставка
- Опубліковано 1 тра 2021
- This video explains why your CNC router suddenly stops working while cutting a project. It is not because of the controller software like universal gcode sender (ugs) or mach3. It is because the cnc router control is not spike protected.
I have seen this happen on BobsCNC router…since I have one. It may happen on other CNc router brands as well. It is not Universal gcode sender! It is a power spike.
The way to fix the router stopping in the middle of a job is to surge protect the CNC router control module.
This is the surge protector I recommend in this video: amzn.to/2QNwKB2

This is an area where I have some experience, although from a different angle. I have been a ham operator for most of my life, and we sometimes will use gas generators in the field to provide power to our radio equipment, and computers. Without going into a lot of detail I will simply say there are plenty of opportunities for dirty electricity to be introduced into the system. One thing that we have learned to do is to avoid using a source of electricity that is dirty to begin with. When it comes to gas generators, there are the typical over-the-counter generators, and then there are inverter generators. The difference is that an inverter generator if it is made properly will have a clean pure sine wave. Secondly we will use LINE conditioning devices to help alleviate random hiccups in the smooth sine wave we are looking for from a generator. How this relates to using alternating current in a CNC shop is not all that different. My first recommendation is to have a dedicated service line run back to the breaker panel for the CNC. That service line will be rated at either 15 or 20 amps for a 120 volt circuit. If you have multiple devices on that one circuit you can see where the electricity can in fact be impacted as you turn equipment on. By spreading out your loads across multiple service lines to your shop, you begin to attack the problem in a more intelligent way. While the use of quality surge protectors is a step in the right direction, there are on the market such things that are used for conditioning the electricity provided to medical equipment and other sensitive electronic devices. One less expensive way to do this, is to use a quality battery backup system. These devices typically have line conditioning circuits built in.
A better way to literally see what is occurring on that service line is to have someone who is familiar with doing this, is to put an oscilloscope on the service line feeding your CNC machine. We used to do this in various labs where we would have expensive communications equipment in the same area as shop equipment. By putting an oscilloscope on that line we could see the exact instant a piece of equipment was turned on and the effects that would have in the signals received in the communications equipment. Getting spikes and other forms of noise into the CNC router is never a good thing. And as you pointed out we spend quite a bit of money on CNC equipment so why would we go cheap when it comes to providing electricity to that same equipment? If you hire an electrician to run a dedicated line from the breaker panel to your shop, and I strongly recommend you hire this out if you don't know what you're doing, the cost to have a second or even a third dedicated circuit to your shop is not going to be that much more money. As long as there is additional empty space in your panel to accommodate the additional circuit breakers, you should do just fine. I would recommend that you run 20 amp circuits and not 15 amp.
Having said that, these problems are exacerbated in those areas that have dirty AC service. What I mean by this is some communities have more problems with reliable power service than others. Though it seems like an extreme example, imagine your lights dimming when your neighbor turns on his air conditioner. You may have noticed that many electronic devices have a large mass on the power cords to the equipment. These are called ferrite or toroid cores. You can purchase these separately, and by simply clamping them over your power cords may find that the spikes can be completely removed sometimes.
Dirty power is more common in households than you can imagine. The electricity powering hospital equipment oftentimes is much cleaner than what we use in our homes. How do they do it? A well-made surge protector with a high joule rating or a clamp-on ferrite or two might solve these type of problems for some folks. Others may have to resort to more expensive means.
As always Garrett, excellent topics!
G, there couldn't have been a better deep dive into this subject than this post. I just learned a ton. I forgot about dirty electricity from my days as an engineer and solving blown boards issues.
I don't believe it's so much dirty power, rather emi from motors/inverter getting onto the usb cable interfering with the data transfer. Still need to try myself but I believe a good quality shield/ twisted pair cable with some ferrite clamps could be the go.
I ask because I don't know. If there's a surge in power won't a surge protector just plain break the circuit and turn off power and the instrument will stop anyway?
I just put my CNC on a UPS. I wasn't thinking about the surge situation as much as when we lose power, it takes 8 seconds for our generator to kick on. However, now that I'm thinking about it, my UPS might not be delivering the clean power I need as my generator is not an inverter one...@@robrickert9018
Brother you saved my day with this video today. 4 times in a row today after 5 minutes my MillRight CNC just stopped. Plugged the router in a separate outlet was back in business. Thank you for this video.
Right on Shane! Glad this one helped you out.
The surge protector is a good idea, you should also have a “dedicated “ power source for only the CNC and ferrite filters on everything! I had this same issue until I installed the ferrite filters.
Hi RB. I'm working on the alternate power source. It's a little tricky in the new (old) shop.
I don’t have a home built CNC and I have never had this happen But I enjoy watching your videos and MANY have been very helpful.
I hope things are going well for you, again Thank you for for your videos
Things are coming back up after that little lull.
Hey there. Great video. I'm getting my new OneFinity set up and looking into what's possible in my new (old) shop for isolating circuits. My question is whether or not you have gone back and tried testing using the same devices in a similar configuration since having installed your surge protector and/or UPS to see whether or not you are indeed seeing fewer faults. Have the intermittent interruptions stopped (completely/mostly) after adding the new components?
Hi Brett. I have not had a problem since the surge protector was added.
Thanks Garrett For the tip I've had this happen several times, and could not figure out why, now I know.
George, glad to help!
Your exactly right. My brother in law had the same issue when he got his cnc a couple of years ago. Surge protector straightened it out. Thanks for the info. I don’t have a surge protector but it will probably be a good idea to get one for the peace of mind.
Hi Alex...there's nothing more frustrating than that thing stopping in a job. Well, there is one thing more frutrating...knowing it could have been prevented
I’m glad to hear you solved your issues.
I’ve experienced the very same weird things for a long time with my laser cutting machine and, unfortunately, I’m still dealing with them sometimes.
Where I live we have a quite dirty AC line.
So, I tried to solve by the followings:
- dedicated 16A line directly from my main panel, no other electrical devices on the same outlet;
- pure sine wave UPS to power laser machine, EMI filtered plug, accurately grounded chassis, correct cords size;
- water pump, air pump and any other inductive loads on different lines;
- EMI filtered USB cable from a stabilised 5V dedicated source for logic controller board;
And yet, sometimes it happens again…😔
Reading here and there, someone said it might be related to USB grounding problems (not AC grounding).
Someone else said it’s just a matter of quality of the controller board (no names here, but some “cheap Chinese clones” of well known MCU’s have PCB quite poor designed…).
Honestly, I haven’t tried the surge protector suggestion (even if I’m quite sure my AC line is quite safe and sound now 🙂).
I’ll probably give it a try.
Thank you for this tip!!!
Bye 👋🏻
Fulvio, those are all great ideas! Thanks for sharing them my friend.
Add some Capacitors to the control board to help filter voltage spikes. I also added clip on ferrites on long cables to filter inductive loading feedback and reduced the overall noise on my cnc. I had the same issue for the longest time. I have an oscilloscope to hook up and find these issues. Never had a problem since.
Chad, those are great tips! You are definitely ahead of the game on this one. You should sell a kit that other CNCers use to filter out inductive loads and reduces electrical noise!
Static through the wires can also cause this. mostly from the vacuum or from the actual router it's self. I see you have the router power cord tied in with motor and end stop wires which are unshielded. You may find you still get random stopping even with the surge protector. if you do, separate the routers power cord, static ground the vac hose and get shielded wires bundles for the motors and end stops.
Thanks 3D. I didn;t think about that. Will fix it now
Thank you for another excellent presentation. I added a short outline of possible issues that are common electrical sources of problems; I hope this helps the viewers solve a few potential problems! 😎
I saw that Paul. Thank you so much for doing that! I appreciate it and I know our fellow CNC'ers will appreciate it too!
This video helped me out a lot. I was getting super frustrated. Unplugged a few things and everything was all good.
Karl, I'm glad it was helpful and that you were able to get things sorted brother!
For sure ! I had the same problem yesterday and separate all power supply from the CNC . Maybe ARDUINO doesn't like spires.
I hope it will be done for next job...
I also use shielded wires for every electronics networks .
Thank you for advise !!
Hi Jeo. Sorry for the delayed responce. I got overwhelmed with messages on this video. Thanks for sharing your experience. Yes, shielded cables will make a lot of difference.. I'll be doing that to mine.
I discovered, the hard way, not to unplug something from the power bar that my CNC is plugged into. I unplugged a fan I had plug into the power bar and my CNC immediately stopped. It was very frustrating. Now the CNC is on its own dedicated circuit and it hasn't happened since. Great video.
So many solutions...the best is to keep it isolated.
There are three (or more) things to explore: 1. Size of the wire in your power cord or extension cord to your machine. 2. Which side of the panel grids is your machine connected? 3. Distance from your panel. Let’s explore! The size of the wire gauge is very important as many cords or circuits are sized for just one item using that circuit, so you get voltage drop in the line. The distance is also important for the same reason: the longer the run from the source, the more the voltage will drop.
Which side of the electrical panel circuit bars is the router and/ or control circuit connected to? You have a panel with two sides or grids for incoming power in a 220 service. If too many circuits of one side of a 110 line in the panel are on the same side, have the circuit breaker switched to the other 110 bar in your panel. That way the voltage will be more stable. Other users in your area can also affect your service if they have large motors, welders, stoves, or such that are in use at the same time. You can ask what they have and when they use more items all at once. Is your dust collector, air conditioner, heat pump, stove, etc., in use while your router or spindle is running (especially important if it uses 110 volts)? Does your CNC have a dedicated line from the panel? Is the wire size correct for the distance and load (amps) of use? If you have conduit from your panel, you could have the wire size/gauge changed to accommodate the amperage increase along that circuit, because simply changing the circuit breaker to a 20 amp won’t make a difference if the wire is the same gauge. Electricians are notorious for putting too many outlets, light fixture, etc., on the same run from the panel, as that conserves wire costs for separate circuits. Your circuit can be monitored with a meter to check amperage and voltage while the CNC is running to watch the changes along that circuit. Your spindle and stepper motors may need separate circuits (or sides of the panel service) to run efficiently without lower power conditions if all are 110 volts. Surge protection of an adequate size is also important, as is the power back up/load characteristics of the unit. Filters are helpful for any computer circuits, as small changes in volts or amps along the lines disrupts the signals, as is the quality of that network wire: is it Cat 5 or better shielded cable from your internet connection or is it on a closed or separate loop from the internet and is the cable shielded, especially from the control computer to your stepper circuits and motors? All wire has a ‘field’ around the wire along it’s run from the sources it uses or controls, so keeping the power wires near your computer separated from the network cable is helpful, as much as possible for high quality signals.
I hope this gets you thinking out the issues before they begin or solves some of the problems encountered. 😎
Oh, I forgot to mention to look at your electrical panel and see how many of the single pole (110 volts lines) are on the same side of the panel circuits. If all those circuit breakers are in a line on the right or left, then having some placed on the opposite side (the other 110 v bar) of the row of switches may help. Consult with your electrician to have those changes made behind the panel cover for safety!
Wow thanks for the tips Paul. This will help out a lot of people for sure! Electrical problems are very tricky problems to figure out. Wouldn't you agree
I think this may be what I’m experiencing. Thank you so much.
Kimberly, you're so welcome I'm glad it helped!
for those with 3018s having this problem, check the bundled power supply. they are most likely underpowered and not made equal. I have to add 10000uF capacitors to stabilize it. taking off the power supply to the motors and laser from the controller regulators also provided great improvement. been using >2 meters of wires from the controller to the hardware with no ferrites with no problems ever since.
mariomanus3176, Thanks for sharing your experience! It's great that you were able to troubleshoot and find solutions for your CNC machine. It's always helpful to hear what has worked for others in similar situations.
HI Gareth, you have helped me in the past and i hope you can do it now too. I have tried the surge protector but it didn't help in my case. My router stops moving gradually after about 60-70% of the job. The spindle spins but it's not moving. Any idea, what could be happening? Thanks in advance.
Does this happen on every file? Or just on this one? Try a different toolpath file my friend. This will let you know if it's your machine or your programming.
@@IDCWoodcraft i will try and let you know. Thank for the reply!
Thanks for info, I currently use a surge protector power strip.
That's all you need, my friend
I agree. I use a separate circuit for all things running on or around the cnc.
I need to do that. Not run EVERYTHING off one circuit...
Thanks you have confirmed the problem that has been giving me a headache for days :)
ScottBrown, you are so welcome brother
thank you so much, I was wracking my brain over the stop issue. Surge protection so important. Thank you I get it now. Suscribed.
BrentSaulic, you are so welcome my friend.
Great job with your diagnostics. Definitely protect it. If you are able go with an offline controller if feasible. Great content. keep it up. always looking for it.
Hey Gary. Thanks. I will not stop delivering for you.
I haven't had a problem since I saw this video!!!
Robert, that is great news brother. Happy CNCing!
Now I get it! Thanks for the good work
He Cloyde. lol...I got a hundred comments on this video and you're the only one who said it...
I'm going to post another question here because I love the instructional videos you produce, and I have already gotten some good answers from you and others here. In fact, your videos were instrumental in my deciding to finally purchase my very first CNC.
I have created a file in Vectric Vcarve. It is a layered mountain scene. I did import a picture to use but I did not use the "Trace Bitmap" function because I was going for a different look. Instead, I used the "Freehand Drawing" tool and basically outlined the top of the mountains and then drew some more wavy lines inside to represent the face of the mountains with the same tool. I end up with a lot of individual lines. The only toolpath operation I can use that will make it look anything at all like what I am going for is the "Quick Engrave" set at outline.
The weird problem is that it won't just carve all the lines at the same depth. It seems to randomly pick and choose. In some case it starts off light and then digs in deeper. In other cases, it goes perfectly even and light (Not as deep). In some cases, it barely touches the wood at all. I have tried this on a surface that was already flattened by the same CNC, so I know the surface started off flat.
All I want to do is draw a series of lines and tell the CNC to run the Vbit over those lines at the exact same depth everywhere. Is this more complicated than I am imagining it should be?
If anyone has any suggestion, I am listening intently =)
Haphhhazard, this one is a bit tough to answer over a comment brother! Join me on my Live session on UA-cam Wednesdays at 6PM EST. Id be happy to help you then brother!
I'm having this issue now. Using UGS, Workbee CNC, VFD with spindle. I have been thinking along the same lines as Garrett and have been trying a job that stops, but haven't switched anything on or off in my cabin. As the job stops around the same time eacg time, I thought about what else it might be. I have the USB cable running through the cable train. I think it might pick up spikes from the motor drives. I am buying another USB in order to seperate the cable paths. I removed the spindle cable as this crashed the system all the time. I would recommend cable seperation where ever possible. I'll report back in a few weeks with some progress. Thanks Garrett for your help!
Hi Mark. It seems the router wires and controller wires being too close together also caus this issue...I think you said that
I almost replace GBRL controller boardx3, spindle, usb cablex3, laptop x2. Still having this hang issue. My next try was switch to mach3 controller board. After watching ur video I probably will get a UPS first. Thank a lot. Thumb up 👍
Hey CK. You are most welcome.
wow, I actually went and purchased a new router because of this. Nice to know that it might happen to that one also. I guess now I have a backup router.
daniellecompton1110, glad to hear this one helped you my friend.
I’ve run my router for over 12 years and never had that problem. BUT, I have a factory built unit, possibly with more built in filters, clean electricity, and, I had a dedicated 240 volt circuit for my CNC and a dedicated circuit for the computer. (I will never use a laptop to run my CNC).
That said, a friend that had the identical router as myself was getting random stoppages and he too had clean power and dedicated circuits. He discovered the cause while looking out his door, heard the CNC crash and saw a tow truck driver keying his mic at the exact time the CNC crashed. He called the owner, brought over a truck, started a test file, and crashed the CNC every time he keyed his mic to talk to home base. My friend was able to install a filter that solved the problem. CNC’s can be finicky.
This is a very interesting situation. Just goes to show how elusive it can be sometimes. Thank you for sharing it
I’m having similar issue but on one axis will stop moving and then get out of sync. Mach3 shows it is still going and then it continues but in the wrong location. Happens on y and z access. Put up a few videos showing the issue. I am occasionally turning on my shop vac to clean up shavings. Willing to try surge protector as support for my CNC is not very good.
Mace, sorry to hear you are having issues with your machine. Keep us all in the loop on if your surge protector fixes the problem.
Wow if that helps you are my hero. I couldnt find any solution and was about to change my grbl controller for something else. Did your surge protector fix the problem? It might be also some electromagnetic/electrostatic stuff going on from turning dremel on.
Surge protector seem to stop the issue. However, that did separate the high voltage wires from the low as well
what is the blue painters tape on your cnc for
Jeff
Hi Jeff. The BobsCNC rails are exposed and get sawdust buildup. This causes a problem since the sawdust gets cruched between the drive bearings and rails. so the painters tape acts as a barrier to stop the sawdust from building up.
Another awesome video!
Thanks Vy!
Thank You! Thank You! Thank You!
Real Human, you are so welcome! Happy to hear this one helped you.
Ahaaaaaa so that's why my machine stopped :)))
I thought that on my toy 3018 cnc the cheap factory stock usb cable was the problem.
Thanks a lot !!!
You're welcome, my friend
I had something similar happen yesterday … yes, my router was still running and stopped moving, but Carbide Motion was on the Connect Cutter screen, like it would be if the application had just been opened. I’d had this happen once before and most people said that it was probably static from my dust collection. I needed to get this thing done, so I re-ran the file with dust collection turned off.
The power for the dust collector is already separate from the CNC computer and controller, but I haven’t tried anything yet regarding shielding static or EMI.
B-radg, glad to hear you figured out the root of the problem. Funny how such a small thing like static from your dust collector can mess up your whole day!
@@IDCWoodcraft: Yes, but I want to be able to run my dust collection, so maybe I need to look into shielding and so forth.
Thanks for the advice on the surge protector. I just ordered one. I am also experiencing another issue though. While using my CNC to flatten some walnut with an Amana RC-2251, flattening bit, I have now experienced (4 times) the spindle shutting down in the middle of the file run. Sometimes the spindle just shuts off, but the file continues to run, and the controller still moves the gantry. Sometimes the spindle seems to bog down or slow down and then shuts off. In all cases the controller still moves the gantry in the X and Y directions, but with the spindle off, this creates obvious issues.
Do you have any ideas on why this occurring? I'm guessing a bad spindle. I checked all the connections, and they are fine. I never get error codes and I'm only taking a 1/8" pass. The cutters are not dull. The FPI and RPM are set to Amana's recommendations. Any help would be greatly appreciated. Gary
Gary, that's a strange one brother. I agree it does sound like it could be your spindle. I'd recommend reaching out to Amana directly and seeing if they have any tips and tricks for you to try out! They should be able to help you out the best on this one!
That is a large bit. What type of spindle are you using? I use Amana bits as well, and the feeds and speeds they provide are what the bit is capable of. However, non industrial CNC's typically cannot achieve those feed rates and chip loads. The effort required to push the tool through the work piece at those rates is high. It also loads the spindle quite a bit. Just manually try to push a hand router through a piece of plywood at 200 inches per minute and you'll see how hard it is. If you have the ability to get a torque curve for your exact spindle, select the lowest rpm where your torque is the highest and adjust the feed rate using that rpm and the lowest chip load value from Amana's range of recommended values. EMI usually doesn't affect the spindle. I would guess your spindle VFD thermal or load limits are being triggered somehow. Does your spindle have any internal thermal limit protections? Try running the same g-code and just take off about .01" and see if it completes without problems.
@@dvongartzen I think you are on to something there. I am using a Hitco 4 H.P. Spindle. I will look into the internal thermal limit protections (it might be worth noting, I'm in Fresno Ca, and it was hot in my shop already) and I will read more about the torque curve. I did talk with a very helpful Amana representative. I also mentioned to him that I used this very same bit in a 1.75 H.P. router and could make 1/4" passes all day long on a flattening jig. HIs response was, and it made a lot of sense when he said it, was that I was probably adjusting the feed rate by listening to the motor, which I was. Obviously, the Spindle and the CNC can't do the same, although it would be cool if they could. I have since run it again with all the same settings, but I reduced the pass to 1/16". It did just fine. I also spoke with AVID, the company that sold me the machine. They say that I shouldn't be running a bit over 2" wide. I have ordered a smaller bit. I am concerned about the temperature, and I expressed this concern with AVID before purchasing their spindle. I spoke with them about whether or not I should be thinking about a water-cooled spindle, considering the summertime heat we get here. They assured me it wasn't necessary. I also purchased a refurbished spindle from them (1k savings). So, these last two things, heat and refurbished, have me concerned that my spindle may be at fault.
Thank you@@IDCWoodcraft that's exactly what I did and they were helpful.
Exactly same problem I'm facing from two days.. Now u got it what to do now. Thanks for the video
Wasim, glad to help just in time! Let me know how it goes.
Hey Garrett, so it’s been a year now, did the surge protector fix the issue? I am having that issue, however nothing in the shop is been powered on during the job.
Andrew, it sure did brother. Your problem might have to do with the power going into your shop.
@@IDCWoodcraft possibly. Thanks.
Do you how many hours you have saved? You nailed it, I feel foolish that I didn’t pick this up. You are my hero!!!
Ed, you are so welcome my friend!
Thanks for the info
Hey Grandpa. I've watched some of your stuff. Definitely like it. Glad you dropped by
I never would have figured that out on my own. Thx
howarddahlberg5617, you are so welcome my friend! Happy CNCing.
It happen to me When I turned on the shop vac, I kind of
suspect that to be the problem but I was not sure but now I know thanks
It was stumping me for a while like it was you. Now we know
I think this must be the solution I've been looking for my 3018 pro max as well.. it keeps stopping mid-operation..I'll try out your surge protector idea
Tseten, give it a try, it definitely can't hurt my friend!
Thank you for the useful information. Now I knew what happened with me. I'm thinking of using a ups.
Hi Rami. It was frustrating the hell outta me. So I know what you felt like
@@IDCWoodcraft Today I ran my cnc on a ups and it worked like a charm. Your videos been a lot of help for me, thank you for your efforts.
@@ramisafi1976 really glad to hear that. Its such a struggle otherwise. Whaddya going to make first
Also going with battery backup combined w/surge ... After 20 years building and servicing PC's, I have made a small mint rebuilding software after power crashes, or worse, brown outs, and causes a disk write to drop, or corrupts, immediately causing Windows heartburn, only to be discovered at the next bootup, or worse, it will not boot cleanly once the power comes back ;)
You, my friend are a top-notch techie!
When I work with my Workbee, regularly and randomly, it stops working. The spindle continues to rotate, but the axes does not move forward. To continue to work, I have to press the pause button of the software and then the run button. In general it restarts but not always.
I have not this problem, if I start à job with the spindler/vfd off.
Do you think I can solved this problem with your solution?
Thank you in advance !
Hi
Patricia. That random stopping is definitely annoying when you don't know why. I hope this solved it for you.
@@IDCWoodcraft Thank you Garrett!
Just happened to me…..do you have to rerun the program or is there a way to pick up where it stopped ?
Thanks
Hi Tagdaddy, you can re run the program or you can start at the specific line that the machine stopped at by editing the g code. If its a long toolpath, i recommend editing the gcode. If its a short toolpath, i recommend re running it.
This happened to me yesterday 5 minutes before the job was done, I shut down mach 3 and it always asked if I wanted to save the fixture and this time I said yes, I opened mach 3 up and it saved the coordinates where the router was, I reloaded the g code and started it at the line where it stopped 21443 and it finished with no problems. I will be getting a good surge protector today
Been programming 5 axis CNC CMM , and lab manager for over 20 years. A requirement from manufacturer for all the machines, before they will even install it, that it must have a dedicated regulated & filtered power supply. You do not want to feed any CNC type machine with potential bad juice.
Exactly!
I had similar issues and i found it was my LED lights in my enclosure. I stopped using them and have not had any issues since. I plan to put an UPS on the CNC to stabilize the power flow.
Interesting. We never know something so minor could cause that problem.
That is strange! I run all LED lights and they don’t seem to effect it. When I was having issues I tried it with lights off and still would stop. After installing the ferrites and grounding the chassis haven’t had a issue since!
Well I'm going to give it a try
Rick, good luck.
I had an another problem how to regain last position or start your machine job where it left after the sudden power loss shut down or latenight go to bed to take sleep leaving your job for next morning
Strong, that is a tough one brother. Your best bet is to separate toolpaths into different files, so when you have a disconnection you only need to run that one specific toolpath again!
Thanks!
KevinVerville, thanks for the support brother! Happy CNCing.
Used to have this happen all the time, especially when doing stacked text in Easel; Now I use VCarve and when running the CNC, that is the ONLY thing running on that circuit.
Odd. I wouldn't expect Easel to cause that
I’ve never had this issue with any software other than UGS. I’m not sure if others will do it or not, but the last 5-6 years has been problem free until today with ugs and a genmitsu.
ElectricAdvantage, sorry to hear UGS gave you troubles brother. Have you tried using gSender? Here is a link: sienci.com/gsender/?ref=idcwoodcraft
@@IDCWoodcraft I have not tried gSender yet, but I have realized that this is most likely an EMI issue or a bad power supply with my machine. It’s triggering false estops when the spindle is under load.
I also need additional help. My router spindle works continuosly without being able to stop. Even when i try to stop it in the software. What can i do?
Uzobandwagon, your best bet is to reach out to your machine manufacturer on that one brother! They can help you with your specific machine.
I have the same issue. I think that I am goign to try and use a small UPS on the electronics side of things. This should smooth out the power so turning on motors, heaters and so forth from causing brown outs or spikes.
anytzhing to keep it protected
@@IDCWoodcraft could you reply to my message when you give it a try? Thinking it might be more of a brown out scenario rather than a surge. Similar to when you run a vacum and the lights dim in your house. I think the logic high level is dropping to a state that is to low to be a logic high hence it hoses the data and the control board can't recover. Thanks!
I’m experiencing a similar issue but instead of the router stopping, it gets “confused” and plunges too deep into the wood - completely destroying the design. Do you think this could be solved with a surge protector? It doesn’t seem to be the router or the machine itself. It usually gets confused around 72% completion. Any tips are beyond appreciated!!
Eily, have you tried running a different toolpath to see if you have the same issue brother? That way you can rule out an issue with the gcode!
Same issue as yours Eily..
Until now, I don't know why.. I will try to install voltage surge.
Interesting. I came to a similar theory. I installed a dedicated surge protector for my CNC and while I did notice a positive change in the first few months, it again started to fail. Best I can guess the filament is not longer functioning and now I am getting the error stop again.
I'm now looking at a dedicated power run for my cnc on a separate breaker to see if that improves longterm functionality in tandem with a surge protector.
Other suggestions from this video were to make sure the cables are shielded
@@IDCWoodcraft gotcha, they are.
@@IDCWoodcraft I will say this as well. I have the same issue when setting up the laser and the cnc at the same run times, one will knock out the other.
Sir, I had the same problem as you. I bought a strip with surge protection, but the problem did not disappear. what could i do? 😢
nsMisiek, I'd recommend reaching out to your machine manufacturer directly on this one if it didn't fix the issue for you!
Just got a used shaepoko xxl3 it does this in the middle of every pattern I’ve tried to run. It stops in the same place in the pattern every time. I don’t think it’s a power problem because I’m sitting there watching it run and not running anything else except the heater. So frustrated!!!
Richard, I recommend trying a different toolpath and seeing if you run into the same issue brother.
Battery back ups for the win. Thanks for your help very much appreciated, now I can begin my CNC journey
HELP ME PLEASE would that be the only reason they do that is a spike in power I have a 5x10 cnc that randomly stops in the middle of cutting parts its driving us nuts
Hi Keith. I am not an expert in this area. I just know electrical noise is a major culprit. There are other factors that can come into play. I suggest the first thing you do is contact the maker of the machine and get their advice.
@@IDCWoodcraft we've done that they said check E stops check wiring harness plugs and connections.
Screws are tight
Plugs nd sockets are cleaned
Checked the pins
Wires aren't pinched or broken
No bare spots from rubbing
The machine runs a few boards and just stops sometimes it stops a few times on 1 board
Doea anyone have a idea on what is causing this glitch
@@keithholton5559 unfortunately, I am not a technical person so it is not my strong point to troubleshoot technical issues. You might want to go to the Facebook group CNC troubleshooters. They are the technical guys
I've been running mine for 3 yrs and this problem just happened to me just stopped moving. But I was not running anything else and I have always had a surge protector. Also for the last three years I have always turned on other tools even the dust collector and never had this issue. Today nothing else was running. What do I do.
Michael, I recommend reaching out to your machine manufacturer on this one my friend. They should be able to help you best on this one brother!
@@IDCWoodcraft thank you for reaching back out. I really appreciate it. I reached out to them and was told unfortunately this affects all cnc users at some point. I was told it really could be that random and that it could simply be that I was craving on a really wet rainy day. I did end up purchasing a better shielded and Ferrite Choked USB Cable it should be delivered today, we shall see. Problem is they also told me it is so random that I may not be able to replicate it. Oh well I'll work on.
Hopefully it was just a fluke. Thank you again for reaching out. Have a great day.
You can see it on your shop lights they will flicker slightly when you turn on something high powered im in the process of doin a separate breaker for the cnc the workshop is far from the house so its not cheap have to run 200 feet of cable
Hi Kieren. Hmmm, I didn't notice that. I'll watch for that next time.
An power conditioner like APC that has voltage regulator is probably best. Isolates each outlet too so prevents electrical noise
Thank for adding to this Kunstle
Have the problem myself, and have tried to find a solution, but a surge protector cuts off the power and reconnects when the power is stable again, but doesn't it stop the cnc anyway?? you do need to remove the spikes, but not disconnect the power Have I misunderstood something? :)
Iars, a surge protector should keep your cnc from turning off if you have unstable voltage issues. It works off of a variable resistor!
@@IDCWoodcraft Yes I know, but the voltage protecters I know, cut of the power if the peak is to high, and and you can set how long boot deley time you want, normerly from 1 to 300 sec.
Hi ,
In my recent research I can say this..!
Will have to verify..!
So
I can see there is a potential for EMI Penetration.! Especially on USB -based Controllers.!
The Router or any powerful appliance that We may have close-by will create Electromagnetic Frequency which will easily distort 5Volt Signals when any load difference /spike is seen on its line.
Separate the High Power Spindle Cable from delicate Signal Cables
(High and Low Voltage Lines should not be routed parallelly together.! Keep them separate. They may cross at some points . but should not go together.! )
Use Shielded Cables for all signal and power lines and connect the shielding to the Earth Ground at one point on the enclosure.
Keep signal Cables as short as possible.
and Use Ferrite Cores at the transmission and reception ends of signal wires
Better if can Use Ferrites on all low and high -voltage cables
Use Ferrite cores on USB cables and Make those Cables as short as possible.
user-oq9ml8jb1t, It's great that you're doing research on EMI prevention for CNC setups! Proper cable management and using shielded cables are important steps to mitigate electromagnetic interference. Keeping signal cables short and using ferrite cores can definitely help reduce the risk of signal distortion due to EMI. Make sure to properly ground the shielding to minimize any potential disruptions.
Is there anything that might cause a toolpath to get corrupted?
3D Layers, removing the thumb drive before it is finished saving is typically the problem I have. LOL
Try rewriting the file and that should fix it!
Whats been happing to the program is frezing up router keeps going
Yes, it is tricky sometimes to tell which is giving the problem. The controller or the brains of the machine.
How you call it in spanish, i have the same problem, in the midle of the print my cnc stops.
Cosas, I have to admit it took me a while to figure out why mine would stop in the middle of projects too. Hopefully, you understand why and it's a little less frustrating! Keep up the good work!
At 6:05 I almost thought you were going to juggle with the dremel and router :)
I looked. That was a funny thought. I might try that in a video for some fun
@@IDCWoodcraft eeeh, living on the edge? I would like to see more videos of you in good health :)
Oooh, now I get it. I was almost ready to give up on my cnc. This will definitely help. Thanks for explaining it.
Brandon, glad I could help brother! Don't give up, you can do it!
It just happened to me and nothing was turned on while it was running. It just stopped. Now it won't go back to the xy i set. it started cutting off the original cuts.
dawnb1313, im sorry to hear that brother. Your best bet might be to reach out to your machine manufacturer regarding your specific issue. They will be able to give you better troubleshooting tips for your specific machine brother!
Question
My machine stops BUT says that "all files were sent".
Douglas, you might want to try and remake the file because it sounds like you lost some data between your design computer and your CNC!
Some think to keep in mind
Don't have home CNC machine myself so not experience anything so far But
Fingers crossed 🍀
just protect it when it comes and you won;t have to cross your fingers
How did you reset your router?
Pat, are you meaning when it randomly stops during the project? Or resetting the router in general?
It wasn’t froze..it is moving so slow you can hardly see it moving, so now I have to figure out why
Well damnit. I'm running a Fogbuster mist coolant on mine and that has the compressor kick on occasionally...
Hi Dimman. Sometimes, it just hits us (like it did me) when the problem happens. Now you Know.
@@IDCWoodcraft Thanks for the vid. I'm going to look at cleaning up my power into the CNCs. I have a bigger one (with the Fogbuster that cuts aluminum) that has pausing issues, and a cheap small one that I got before for learning. On the small one I thought it was a loose USB, but the big one would make sense that the compressor is screwing with the power.
Get rid of that arduino and cnc shield, get something better. This does not have ANY filtering and protecting circuit on it, thats why that happens. Why does not your TV or PC shut off when you connect something? You get the point
Multimargejta, good point brother. Shielding is important to have on every device to be properly configured.
It looked and sounded like it stopped before your shop vac was turned on. Unless your sound is out of sync with your video the router stopped almost a second before the shop vac was turned on. I have a question. Is your wiring shielded? What you're showing us looks more like an e-stop being triggered. Break out boards are extremely sensitive to very small amounts of current. Not knowing how your router is set up, is your router set up to retract to a safe Z on E-stop. I suppose the program is still running G-code with the router standing still. My prediction is that a surge protector my not be the answer to all the problems you and others are having. Do your axis's ever seem to jam up?
Hi Jim. Shielding is definnitely an issue that I didn;t think about. Thank you
The problem that I have been having is that my machine will start cutting and after a minute or so into the cut it just goes off and starts cutting a different pattern What could be causing that??
Hi Brian. This is usually because of an underpowered spindle.
@@IDCWoodcraft So I should turn up the speed of the spindle??
@@brianconner8902 what machine do you have?
@@IDCWoodcraft I should first let you know that I am pretty new to this CNC machine. I retired from teaching (elementery for 34 years) and needed some type of hobby to keep busy and from going crazy. I got this machine three years ago and the business I purched it from is gone out of business since then. I use Cut 2D pro for programing and then transfer my drawings over to MACH 3 and I have a Velox CNC machine.
I am surprised that a power strip fixes this. I thought it would need to be a UPS (uninterrupted power supply).
Hi John. That would be a better selection. I didn't think of that. Thanks for sharing it here so others can catch this comment
It happened to me, but I was not running anything else on the circuit. I found that my laptop was turning my usb ports off because it though the usb port was not being used. I had to dig into several different areas of windows 10 to find all references to power saving and usb ports. There were 4 different spots. Not it doesn't happen.
Vance, that is very interesting. I never heard of that happening. Really glad you made a comment about that so others can see it in case power spike corrections don't solve their problem.
@@IDCWoodcraft Yeah. It was happening at the same time point in the file. So I thought it was a corrupt gcode file. So I generated a new gcode file and it happened at the same time point. So I got my offline controller out and put the file on an SD card and ran it from there. It ran all the way through. So I started investigating power management and found the laptop was shutting down the usb ports because it thought they were idle. I disabled power management on the usb ports and now I can finish a project.
Oh I get it now
flashgordon, I'm glad it helped brother! Happy cutting!
G R E A T !!!
Randal, thanks brother!
👍🙌🙌🙌🙌
Nico, glad you liked this one brother!
EXACTLY RIGHT! I had my laser running, walked across the room, flipped the wall switch for the ceiling fan, went back to the laser and it had stopped. My brain was so overwhelmed with cuss words,there was no way to make the connection between the two. I only had the laser a month or less.
Still not making the connection, I had the fan running one day, pulled the chain to speed it up and BINGO, laser stopped.
Of course it happened a couple more times before I made the relationship. I was so proud of myself, I may have wet my pants.
HOWEVER, (yes it never is that simple because GOD heard me the last time and decided to punish me), a few days/ weeks later, it started happening again.
After some time, I realized my computer was shutting down because of the 'operation TIME settings '.
All I can say is, GOD then made up his mind where I'll be spending my hereafter time but it's fault for testing me!
I think 🤔 this is one HELLAVA story.
Will, I'm very proud of you for discovering this. Good boy!!
Did you really take a couple of days off???
Well, yes, kinda sorta. There's only so much business one can leave to the side
A better quality Breakout board ( Bob) and power supply with an isolator wouldn't have that issue.
Hi Talley. I definitely agree
Mine quit the other day just as it finished the last part of twenty.
Hi Ian. Well, you got thru most of it before it happened
I learned the hard way…. Once! Did I spot a new unassembled toy?
Yes you did. A very different CNC that is not on the market. Should be revealed in a week
I just bought my first starter 3018 CNC machine and this has been happening to me. I've only managed to complete less than half the jobs I've been doing. To make matters worse, when I tried recalibrating after it stops (resetting z with probe and resetting the origin for the work piece) and restarting the job, it was always at least a millimeter off (sometimes several centimeters) from previous paths so the project piece is ruined. I could attribute a small offset amount to human error, but several centimeters?
Yabba, that is normal when the machine stops due to a power failure or disconnection etc. If the machine looses its reference coordinates, it is very hard to get the machine back to the precise location where it was before.
Work on finding the root cause of what is making your machine loose connection or stop in the middle of a job. Your
PC might be going to sleep during the cut.
Same for me, brand new 3018, my first overnight relief job was on the v-carve portion, I walked downstairs & the motion sensing ceiling light turned on. I stopped hearing the cnc. Went over & it had stopped & actually returned to 0,0,0. I restarted the job, but now it has over 8 hours of cutting air to return to where it quit. Is there a way to fast forward thru the program to get back to the point where it stopped?
I ordered the surge protector you recommended. Fingers crossed that works.
