Hi, Thanks for the help. Turns out I was TOTALLY mixing my zero and home settings.
Great tutorial! It helped me a lot when I started working with CNC machines. Thanks.
Thank you SO MUCH! Wonderful explanation! looked at may tutorials but yours is exactly what I needed and perfectly explained. This video I believe should be a beginners class of Mach3. again, thank you very much!
Thank you very much for this series of videos. They are incredibly helpful!
Great stuff ,very informative. Going to have to watch it over and over to soak it all in
Excellent tutorial, thanks!
Awesome video Paul. You explain it very well, especially about the machine vs. work piece coordinates of 0,0,0. Great work. Also, it seems that you set your machine home position to not 0,0,0, but to something like 0,0,16 so that the Z is at 16 or so when it goes to home. That makes perfect sense to me, since you want your Z axis up off the table. I think I will watch this several times. Thank you so much Paul.
The person narrating this video is Art the person who actually wrote the software not me
Super helpful vids! I am learning all of it.....Thanks man!
Brilliant control system and great tutorials.
Excellent teacher. Thank you.
wow thanks for that very informative video. I know it has been years but still very pertinent information.
thank you for you page i can understand well good job
Thanks for these great videos.
Very helpful, thank you!
Excellent!!! Thank You a lot!!!
Thank you these vids helped me out bigtime!
Thanks Art, for another outstanding video! Think I can see the light at the end of the tunnel on homing, limit switches, and the G54 and G55 offsets. I notice that the diagnostic screen on my demo version of Mach3 does not look the same as this video, i.e., my home switches are not labeled on my diagnostic screen. I assume you guys have changed that up on the newer version.
The best!!! Thanks
Hi, Thanks. I use Mach2 for dxf to g code. I'll check what you said. Thanks again for the help.
Thanks a lot for this video. Cheers from France
Not sure if I missed this somewhere, but if your limit switches are wired together in series, you need to use the same input pin (10?) for all of them. Took me quite a while to figure this out, almost blew some magic smoke out my ears....
Thanx guys, that was very useful information and easy to understand. Will recommend the tutorial to others.
How did he simulated the switches? What buttons?
You are the man!!
Thank you do much everything is clear now ☺️
Great Tutorial, Thanks a lot
nice video good work!!!
Cool, thanks again. Lost to learn for sure : )
really , I enjoyed it thanks
Very well explained. Thank you
Thanks Art them!!!!
Great video, thanks for sharing.😊
Hi Paul, thanks for all your great tutorials! I have a Mach3 License can I write to you for support?
great great great . thanks a lot for
Hi, very nice explanations.
I still have to make my CNC construction, is there a way to compensate for errors in the construction? example if my X/Y are not exactly 90 degrees,but have some small errors.
Hi,
First I want to thank you for your effort to help us, second; I have configured my machine but when I loaded the gcode file it shows my work out of the table margins, please help me to get this fixed.
these tutorials were made by MACH 3 the person talking in them is Art the guy who wrote MACH 3
we are a reseller and we put these videos up as a service to our customers we are not MACH support
I am sure they will answer any questions you may have
Great job sir
THANK YOU!
Do soft limits reference machine coordinates? If I set my new zero to work on a piece say center of table will I still have protection from overun? Or does that move also move soft limits to new coords?
Don't know if you got an answer. Today my z axis would home sometimes, and come off the switch, other times it homed and then showed the z++ limit was tripped causing the machine to halt. I got a tip on the internet about setting my de-bounce to something other than 0. I started with 500, then gradually went down to 50, and now I can home and back off the switch every time. De-bounce has something to do with electrical noise.
thanks man
How to change the zero coordinates , i don't understand this point?
Appreciate your help.
I am not an expert, but you can check that your axis limit and home are set to the correct pin, that your motor's are calibrated ( meaning they move an inch when Mach3 says they move an inch ), the axis direction is correct, and can check if homing works for an individual axis ( meaning if you have x- y- z+ switches in series on the same pin that if you separate them they can home ). I have my z axis homing, but I don't have motors and limits wired yet.
Are there any particulars for those of who are not using wired limit switches and only depending upon Soft Limits?
This is EXACTLY how my system is configured. Neither the limit switches or the soft limits do anything at all. I've had several people look at it and none have an explanation for why this does not work on my system.
When I set my work coordinates, is that where I put the corner of the board I am using and how do I make sure the board is parallel to both axis. Thank You
The screens are a little different now but still great information.
oh thank you....
Hey Paul, great video. I am new to the CNC world and just got my first 4 x 4. However, I am using Cut2d to generate the tool path, but every once in a while the z position doesn't go up high enough when switching cuts and cuts across the material. Where is this z location to make sure that its high enough to clear the material when going to other areas of cuts on the material. This has happened 3 times but not always. I am sure its something simple but I was hoping you could help me out. I have Mach3 as well. Thanks in advance.
edit the gcode by increasing your Z height
Can you please show how to run a inch g code while my native units are set to mm when I 1st set up mach3
The 4 "Zero buttons X Y Z are green mine r are red I have tried and read every thing . Latest version have followed videos. In last video buttons r red I this video now green ?
As a software engineer I can't help wondering why you don't latch disable the zero function when a fixture offset has been selected?
Hi Paul When i am checking my table cords when i ref all the z moves up and hits the home switch but it does not then move off from it. This happens for all axis. Are you able to tell me what i may have set wrong. Other than that the table works fine and all the motore move in the correct direction.
Am I wrong when saying that the safest way to wire the limit switches, is only a matter of wiring them in a normally closed loop instead of a normally opened loop?
It really doesn't matter if it's active high or low, does it?
I got mine connected in a closed loop with active low (because it's getting the signal from DCM pin), and it works great. If I disconnect or cut a wire, or even open Mach 3 without turning the power supply on, it'll trigger an alarm / emergency stop. 👍🏻
On X axis Or Y, does the slave motor also need an own microswitch for homing?
hi, im using my normally closed ( NC ) limit switches connected to breakout board and I get constant false limit switch trips . im using shielded wire. what can i Change in Mach3 to not have this problem.
Thank you
Great videos,
I am still confused because after referencing home , then jogging to the part and zeroing out my axis to set wcs
then the cross hairs cursor always goes back to the center of the part ?
what would cause this. I want to be able to place the part anywhere on my table within the limits.
what am I missing ?
thanks
Dave
Some wizards set the origin
Hi Paul I'm trying to get my machine coordinates to zero but when I do the cross hairs on the table display are in the center
hi i need help , i have 3040 cnc from china , and the xand y hit the end of travel , is this because i need to zero everything , sorry but I'm new to this ,but looking at your video i think i no whats happening but would like advice please thanks .
I must set the mach 4 in my cnc milling machine. Someone can set me through remote assistance?
what are the yellow dotted lines in my toolpath window? It surrounds my blue toolpath...
Hi Paul,
I just bought a cnc router from China QC 1325 with a leafboy77 breakout board.
Are the port and pin settings the same for this breakout board.
I just can't get the machine to work right.
I really need help getting this machine setup right.
I'm also having problems with the spindle motors.
I have two.
Thank you,
Phil
Philip Tancredi HI i´m fom mexico i thing, i can help you . is not that hard to use or confi. this leafboy card
Great video! i have a question, on my software when i toggle between display mode and table display, the screen doesn't change, i can't see my table view, why is that? i have the mach3 2.0 , is there any way to fix it?
set your soft limets
do you know what to move in the mach to get off the switched on limit switch?
My x axis is backwards. When I push my left arrow key my CNC goes right and vice verse. How do I fix this?
great videos iam new to all this and built the ox build in openbuilds and iam trying out the mach3 now i got Y,X moveing both directions my Z is only moveing down wont move up any help paul
under home/limits -> check "reverse" for z
oky thank you
OK, I'm gonna look stupid but how do I setup my z axis to lift higher between cuts? Right now it drags across the work. I am just cutting 1/8 inch foam right now, so it's not too difficult, except for me : (
At 07:29 I think you switched the (Active High) & (Active Low) meanings by mistake... My Understanding is that: an Active High is a circuit where the switch "Goes High when Activated" [ie. Normally Open], and Active Low is a switch that "Goes Low when Activated" or Activates when Low [ie. Normally Closed] (and this is the safest I guess)
Hay posibilidad de encontrar este tutorial en español?, Gracias.
why???? in motor tuning if the velocity rang under the range of steps per unit the motor jerking whats the problem i could not put feed rate less than steps per unit
Would prefer u explain as u show us the real machine position...thanx
I am new in cnc machine. I have a 3040 china cnc with bobcad software and running in mach3. My problem is that my G-code looks ok in the measurements block in the bobcad animation, but when transferred to mach3, it ends up scaling down my mold. Does somebody know why? I Will appreciate any posible answer. Thanks in advance. Oscar
Hi I have a question, I star running a program and runs a few parts with no problem, suddenly my Z starting go down from - .010 to -.050 on every pass, can you help me.
Thanks.
Hola, he visto tu video para programar el home all limits varias veces, y con lo facil que te resulta programarlo y yo que no soy capaz. El problema no es que no loexpliques bien que seguro que si, el problema es que no entiendo ingles y por eso no soy capaz de programarlo, Haber si se le ocurre la idea a you tube de poner una aplicacion para traducir la voz a otro idioma. Muchas gracias.
I AM NEW TO CNC MACHINES BUT AM KEEN TO LEARN , I HAVE A MACK3 PLASMA TABLE HOME BUILT, BUT IN MILL DEMO RUN IT TELLING ME THAT IT WANTS A E STOP
BUT IT DOES'NT HAVE ON WIRED, SO IT WONT WORK ,SO I SET IT TO PLAS CUT AND IT WORKED SO I DON'T KNOW WHAT WENT WRONG, ANY HELP WOULD BE HELPFUL
Help Needed,
my mach3 gives me VB failure
what do i do wrong?
greets Hans
+Hans van de Zande Did your error happen after adding new vb code or did it randomly happen? Or is it after a new install of mach3?
If it's after new scrips being added there is a error in the scripts are newly added delete them all start over!,
If it happened randomly try reinstalling Mach3!,
If it happened after you installed mach3 and first go an error the windows or linux your using is having an error it's self and needs to be fixed!
Check to see if your Pc has the updated VB 2008-2010on your pc around time of the error, If so you can remove the update in windows update section!
You can home anywhere on the table in our shop the home is upper right
Hi, how can I make both machine co-ordinate and work offset all zero? ( x,y,z axes)
+ismail k For machine coordinate zero, you simply press reference all. To zero work offsets, you go to the Offsets Alt5 tab, click on "Save Work Offsets", then input zeros on the desired work offset, then press save.
This type of thing Is handled when you create the tool path in your CAM software not MACH 3 see your safe Z height setting in you CAM software
HI Paul, I bought this machine 4AXIS 3040 CNC Router USB Engraver 0.8KW Engraving Drilling Milling Machine 800W. The problem is: I load the g code then the machine carves for a minute suddenly stops and does not go anywhere , would help me please
Did you find problem?I HAVE THE SAME ISSUE
Sounds like you dont have a full version of mach 3. It will run either 1000 or 5000 lines of code in demo mode. Hope that helps
Move the router manually to a Z value above the highest point on your work, then press the "Reference All" button in Mach3, then re-zero everything and instead of going down into the table when your G-Code tells the machine to go to home, it will go to that point above your work.
@@abriestrauss5580, It has nothing to do with a full version of Mach3 or not. It has to do with the G-Code sending the tool to home and the configuration of Mach3 setting home to somewhere below the work table.
when it stops at line 500, you have a demo version..what ever you do, it will not pass after 500 and stop..so better buy the full version.
I meant to say, don't have other axis' wired yet.
Hi sir am Vijay from India. I have mach3 controlled CNC Lathe.But mach3 software doesn't support # G71-Turning cycle. I need #G71 or custom macros for that code function.Can you arrange that marco i will ready to purchase that.. Kindly give me the positive response.
we're is strart clip 1
I was on Machsupport D-O-T com and he set up the Z home to most positive. Jeeeez : (
My Cnc Machine..Operate With Wrong Size...smaller Than Original Size In File...
I Try To Calibrate the Axis.. But Calibrate Change Motor Tuning Value..
I use mm Native Units...so I calibrate With mm...But After Calibrate...Motor Have Slow
Move..Very Slow....
what's the Problem Caused..My Machine Operate At Wrong Size..?
Please Help me..
Next to dro is scale set to 1.000
Here is what I did to make the cut same as the plotted actual size.
1. get a pencil and insert it to the chuck (find ways to make it snap like a bit) don't run the spindle of course
2. now to you need the trial and error...on your CAM-cad just draw a 90 degree line with a length of your choice. (i did 100mm)
3 generate toolpath engrave just barely touching the material Zero in on the junction of the 90 degree angle line and start it from there..(material i used is just a piece plain A4 size
4. load the g-code (noting all of those X-Y-Z axis motor tuning especially the steps (mine with stepper 1.8 degree, 200 steps per rev ..2mm pitch lead screw --this is the standard,
NOTE: if u have input the 200 steps on the motor tuning..it will plot very small, tried that) from 200 go down to 28 steps inputted then test..)
if the line plotted measured 100mm then you got the steps correct, if not or just let us say 95mm when measured then try the 29 steps so on and so forth)..until the plotted line gets the 100mm measured length.
acceleration and velocity settings is how the motor wil turn fast or slow and so play with it, not all stepper can run the same speed with same settings. there are NEMA17 that can run 200 acceleration, others cannot. So with an unknown stepper like mine which by the way I am using UNIPOLAR steppers from old photo copiers. I just played those settings until i got the right one for my steppers, and they work perfectly.
EN ESPAÑOL ? GRACIAS
How do I contact you, I have the same problem
Hi Andy all support for MACH 3 is through there website
.machsupport (dot) com
My home switch doesn’t even turn on when I press the hot key to
Active high or low homing switch settings could be your problem ?
Hì Sir
Please help
After I setup and program to run . But the motor running very slow.
I look in to feed rate is 100 %
And when I jog is running normal.
Please advise
Thanks
Tony N setup steps per number
Thank Sir
Homing switch active please fix then home...error coming what is problem
I'm guessing you'll need to edit your G-Code.
OK, He says to home neg but none of his selections are showing that. They are all have red x.?. Also, is there any way to jog AND see the toolpath at the same time? It docks it right where the toolpath is? I am wasting so much time on this it is getting on my nerves.
