Hi all,
I just got all the drives and motors for my Sieg X3 conversion and connected them up on the bench with micro step set to 4. The NEMA 23’s work fine. But the NEMA 34 seemed a lot slower compared to the 23’s. I bumped up the jog speed a little in LinuxCNC again 23’s worked as expected but as soon as I hit the jog button on the Z axis (NEM34) the dive faulted. I reviewed all of the wiring and settings and tried a higher micro step setting. Same result. Now the KL-8060drive seems to be dead. No lights at all and the motor is not locked. Check the power supply and all looks good there. 23’s still work fine. Based on reading here I check the motor for shorts to ground and did not find any. I don’t know what to do next. Are these drives that fragile? I sent an email to Automationtechinc for their advice but haven’t heard back yet. I don’t know if it was a bad drive or something I did. I would hate to get another drive and have the same thing happen.
These are the components used in the build:
