3 Axis CNC router

**JoeHarris** · 29-01-2018

Thanks Dean, I'll have a look and see. I don't think anything is loose or falling off!! Only one I'm not sure on is how tight the square shaped nuts on the BK bearing block should be and whether they are perfectly set up. I've done the best I can, but when jogging the machine rapidly in alternating directions on the X axis it does sometime make a noise and appears to momentarily stall. I'm not sure what that's about and it doesn't do it consistently but wondered if that could be connected to differing tension on the two ball screws? I did not get this when cutting or doing the calibration tests at the weekend. I'll try and video it so you can see what I mean...

Happens 50% of the time with these controller/drive combo and it's something I check for has matter routine. Can happen on any controller really but with the IP-M or S happens randomly depending on how drives setup. Esp if not used tuning software to check Rising edge setting in drive.

Edit: For anyone else reading this that doesn't have Cslabs controller but as similair problem then the same can apply.
The test and fix is the same. Or if the the drives have option to change the leading edge setting use this. Both work same.

I had exactly the same problem and I have leadshine drivers this fixed it.

Thanks saved lots of head scratching.

Joe did it fix yours?

I'm not sure! Need to do some more testing. After devoting a massive amount of time to building my machine, I got it working and then just felt burnt out with it all and pretty much stopped all together. I have decided I am going to get back to it, finish the job and start actually using my machine!!

I know the feeling. Best wishes. Yes, I still live and breath though it has been a good bit close a few times these last years. You deserve to enjoy the fruit of a huge amount of labor. So get to it and have fun making chips. Enjoy and good luck. Hopefully you will break fewer bits in the learning curve of feeds and Speeds.

Nice to see you back again Joe

I think I have found the culprit, there was (much to my annoyance) a loose grub screw on one of the y pulleys which I noticed whilst running Jazz’s pulse test. With this tightened down and thread locked all seems to be well... The test results can be seen here:

No problems Joe.

I seem to remember doing something similar with my bearing spacers as I dropped one on the floor never to be seen again!

Good to see you back at it Joe - hope you sort those spacers out without too much hassle :)

I'm still using this thread as an awesome source of information - I've got a couple of questions though:

Your electrical diagrams are awesome - can you point me towards the software you used?
Your cabinet looks pretty decently sized for the layout - could you share the dimensions? Would you go bigger/smaller if you did it again?

Thanks!
Andy

Hi Andy, I have an updated circuit diagram that I will upload as I had a few mistakes on the last one... take it with a pitch of salt though as I’m no expert!! I just used the cad software we use at work for the diagram, which is archicad. Not ideal but did the job ok!

The cabinet is a decent size, I got it second hand off eBay and it had a few bits in it and the rotary switch already installed. I’d defiantly go big if you have the space. I found mine to be about right. I’ll try and get some dims for you.
