Thanks for all the help everyone.
First I'll respond where I can:
Aren't these the same drives as are having issues here? viewtopic.php?f=60&t=6477
Yes they are, but like Marty said, they have been working fine for me. I don't have any trouble at all until I turn on the spindle.
Hi, I am having issues with my g214's moving on there own when I start cnc12. Have you had this problem? What revision version are your drives? Thanks
I don't have any trouble with them moving on their own when I start cnc12. I don't know what they revision they are, but I only bought them about a month ago.
@drdennis thanks for sharing the video, I'll definitely watch it....and probably see if I can coax my buddy who's an electrical engineer to come out and help me once I've fixed a few of the issues others have pointed out that I know aren't done correctly.
Do you have a closeup of the yellow wire going into and out of the VFD? IS it shielded? Specs?
It's just 13-gauge romex, solid core, not shielded. There's a really good chance that's the problem. It could also be because I bought a cheap chinese VFD, I've heard they cause EMI headaches.
From what you guys have said overall I think I need to take a step back. yesterday I reattached the original spindle control box ground because I had a hunch that grounding that would also ground some of the shielding on the router. It helped, but the z axis moves on spindle startup, spindle shutdown and the z home kept changing while it was running a program.
For now, I'm going to take a breath and slow down a little bit. I was really hoping to make a few christmas gifts on it but I need to let go of that and take good care of this machine that I was unbelievably lucky to get at a price I could afford.
I'll monitor this thread and answer any questions but I'm going to take a step back, go back to my original build thread and start by documenting my build clearly. Then I'm going to buy good, shielded wire and rewire everything.
