William, thanks for sticking around my friend! I love your humor. Hopefully I can save some of our newbie CNC brothers and sisters from throwing in the towel! I know we've all felt that way at one time or another, keep up the good work brother!
I’m grateful for these contents you’re posting. Thanks for taking your time to help us to become good at this skill set. Thanks for always responding to my questions even if they are silly to others, I really appreciate it and it helps me out a lot too.
You totally nailed it for me Garrett. My Bulkman 2.2KW Water cooled was running backwards. I wired it up per a youtube tutorial and this is my second spindle. First one exploded as soon as it touched the wood. This time at least I kept feeds and speeds super slow with MDF
Blaine, it happens to the best of us. Complex electrical components feel like magic sometimes, especially if they are three phase like a spindle. Glad you got it sorted!
Hi! Probaly I have seen the same video, since looks like my spindle spins in backward (counterclockwise) directoin when I set M3 (clockwise) rotation command. Could you please share the right wiring ( I also have the Bulkman 2.2KW Water cooled spindle)? My current wiring is U for 1 pin, V for 2 pin, W for 3 pin
@@VSongu are you still needing this? I have been moving and the CNC is still in a box but I can get the controller out and post a picture of the wiring if u need it still.
Great videos! I've been researching cnc machines for the last couple months and it was quite overwhelming at first, but your in depth videos really helped. I finally just ordered a Longmill, can't wait to get it and start making!
Nice video Garrett. My Shark HD520 came with a water-cooled spindle rebate. But before I got the spindle, I was using a DeWalt 618 router as my cutter. I had no issues with the projects I ran with the DeWalt router. After I received my spindle from Next Wave, I installed the spindle and have everything configured according to instructions and was all set to carve out a 2’ wide yard ornament Thanksgiving turkey from plywood. I put in my 1/8 inch down cut EM to make some shallow interior cuts and noticed big time tear out leaving long strings along the tool path. Smoke from the bit. Loud screeching coming from the bit. I asked myself why in hell is the wood tearing upward when I’m using a downcut bit? It occurred to me that maybe the bit is turning backwards. I didn’t know which way it was supposed to turn. I got my trusty DeWalt router out and turned it on for a second to see which way it turned and it was turning as you looked from the top down clockwise. I turned my cnc spindle back on and sure enough, it was turning counter clockwise. I called Next Wave customer service and told them what was going on and they said they had gotten a batch of reverse wired spindles and sent me a detailed email of how to fix it. I just had to reverse two wires in the vfd controller box. It was aggravating but easy enough to fix. Every time I have had question for Next Wave, they’ve been very responsive. I’m glad you posted this video. It should help people troubleshoot some of these problems themselves. 👍
Im happy to hear that you figured it out in the end Douglas. Those VFD powered spindles can be tricky to wire up! Its always good to have a trusty DeWalt on standby incase you need it isnt it?
Thank you Garrett. Recently purchased Carbide 3D Shapeoko 5 Pro with VFD Spindle. I was buring through everything and after watching this video I went out to check and sure enough spindle was spinning counterclockwise. Contacted Carbide 3D support and they shipped out new spindle the next day. Thanks again.
As always very informative and accurate. I used to work on a Homag venture 2, and you could actually set clockwise or counterclockwise for every different tool, on the tool library.
Mitsos, thanks I'm glad you enjoyed it! That sounds awesome, I'm jealous I wish I could set that in mine! That would be super helpful for those bits I was talking about in this video!
Hey Dan. I would use a down bit almost all the time except when I'm cutting all the way thru. In that case, I would use a compression bit (like this → bit.ly/3O8yKvO). Btw, how did you find this video helpful?
Thank you for all the videos you make. Very helpful and informative. great appreciated. One question. Why does the Longmill only have a 90 day warranty> Everybody else does a year. Thats a big difference. That is whats holding me up on the Longmill purchase.
Garrett, you're an absolute legend. My self-built cnc was turning anti-clockwise and I would have tried 10 other things before that setting. Thanks for saving my CNC. Subscribed!
Dull cutting tools can cause tear out, burning or numerous other problems. Using carbide tooling will have your cutting tools last longer. Carbide is simply harder and will stand up longer in abrasive woods and other materials. Taking too heavy a depth cut, especially when cutting a slot cut at too high a feed rate can cause the tool to choke. It can just not evacuate the material fast enough to continue the cut. The material can pack up in the tool flutes and prevent cutting. That can mean burning, tool breakage and piece damage. A spindle rotating the wrong direction for the cutting tool being used will never work. When viewing your spindle from the top, the spindle should be rotating clockwise. I have a CNC Shark. My spindle router rotates the correct way. One of the nice things about the Shark, is it turns the spindle or router on and off for you. However if it is making the spindle turn the wrong direction, obviously that is not good. However in the settings on the pendant, there is a reverse polarity feature. Reverse the polarity and problem solved. I don't know why some routers need to have the polarity reversed, but that should fix it.
CNC Programmer, wow thanks for such an in depth response. You made some really good points about causing the tool to choke. I'm glad you didn't have this experience of the spindle going backwards on your Shark! Thanks for sharing the change polarity feature, I'm sure this will help a lot of our CNC brothers and sisters out!
But I clearly clicked on a vector just like you clicking on the rectangle or the square and you see it's highlighted but it gives you that message. Of course in your video you did forget to click on it at first. I'm using aspire
Thanks for another great video. Garrett this came to mind as you were speaking ....if you are using a router on your CNC, what is the norm run time a project should be? Because if you have a project with a run time of 2 hrs for example (as calculated by the software) and you need to change bits along the way, the router is generating heat for a prolonged time. Do ya stop , decrease the number of passes, or take long breaks between projects? Because this eventually will breakdown the router, possibly break the bit and make it difficult to change the router bits due to heat or something else. When is enough is enough to stop the router to cool down? What is your take on this? Thanks
That is a great question Max. Project length doesn't really matter for the most part as long as you are cutting within recommended feeds and speeds for the router bit and getting good chip evacuation, you will not see any heat buildup in the end mill that it is not designed for. Stepper motors that are attached to the CNC can run almost continually for days on end if you ask them and still work perfect. It's when you start to overload the CNC and ask it to perform cuts that are beyond the scope of its design is when you start having problems. Two hours though? No problem! Cut away my friend!
Hey Garrett, quick question I’ve been running a porter cable 27,000rpm router with an ssd relay to my mainboard i was wondering why my spindle wont run effectively below 24,000rpm im trying to get down to atleast 20,000 but it jumps. My spindle is running clockwise aswell i just cant seem to control the speed I’ve been running faster feeds but still burn marks any idea?
llluckyent.9133, I'm not too sure on this one my friend. It's a little tricky to troubleshoot over comments. I recommend reaching out to your machine manufacturer on this one. They should be able to give you a little better guidance on this one!
I'm facing an annoying problem in which the router bit is leaving an impression of the tool path it has taken. I have tried everything I can but nothing seems to work. How can I fix this?
I really wonder how do you cut with feed=35 inch/min and speed=22000 rpm when use 1/8 Downcut with 2 flute (derived from your pdf), with the same parameters and the bit I get strong burning?
@@IDCWoodcraft Garrett, thank you for your kind response! Yes, my spindle should spin in the right direction, otherwise an end mill would break immediately as soon as it touches wood. I have tried to execute essentially more aggressive penetration with this 1/8" bit utilising Cutting feed = 70 inch/min, Speed=18000 rpm, Feed per tooth 0.002 inch/tooth, and it looks decent but my bit has broken prematurely after several metres.
can you help diagnose a problem? I cant leave a picture but its fairly easy to explain....... When Im using an endmill I cant see any chatter in the workpiece, but when Im using a big 90 degree V bit it "appears" the bit is moving up and down, which is really easy to tell when using V bits as Im sure you already know..lol. When im using the V bit and I miled a bunch of circles and it only occurs in one small part of the circle, maybe about 30 degrees of it and allways in the same spot.

Great to hear JR, glad that it got fixed for you at the end of the day. Maybe it was a bad lot? And they just kept sending you parts from the same lot.

Man I set up my cnc router and thought everything was good to go. I start cutting holes in my spoil board. when I cut them there was burning and the smell was bad of course, but i fought thru it adjusting feeds and speeds.

To be fair Garrett, I posted a gig on one of your tutorials, I am now going to go through list, find the ones I watched and post some kudos. This one I learned from and it might of been the one that led me to buying your bits.

Michael, thanks brother! I'm glad things are smooth sailing for you. I have fingers crossed that it will stay that way and if not you'll know what to do my friend!
I wish I watched this video sooner. My Makita router overheated again and now is pulsating in and out at slow and higher speeds. My guess now after watching this video is that my bits are dull, which makes sense since I have not sharpened or bought any new ones since I started using my cnc a year ago. You mentioned that you cant really sharpen a spiral bit, but what about a ballnose bit, or would that also fall into a spiral bit category?
JCraftvfx, so glad to hear this video helped you brother. You are correct about the ball nose bit and sharpening. It typically is not economical to sharpen bits after you use them.
@@IDCWoodcraft Could a core box ballnose bit be used instead of a spiral ballnose bit? A bit that I could actually potentially sharpen since its got straight edges.

You mentioned that you cant really sharpen a spiral bit, but what about a ballnose bit, or would that also fall into a spiral bit category?
JCraftvfx, so glad to hear this video helped you brother. You are correct about the ball nose bit and sharpening. It typically is not economical to sharpen bits after you use them.
@@IDCWoodcraft Could a core box ballnose bit be used instead of a spiral ballnose bit? A bit that I could actually potentially sharpen since its got straight edges.
Perfect. Well explained. Thanks
