Problems with Lichuan Ethercat servo drive

havenofish , That is mm. It happens on Y and Z. I'm not playing with the Xx gantry axis at this point.

Darium, It is within the amplifier as far as I can see. LinuxCNC is sending the correct target position, and the machine is actually where it says it is, but it MAINTAINS a random (small) offset I can jog it around with the pendant and the offset stays the same. I can manually force the servo back and forth a bit, and it returns to the same incorrect position.

" I can manually force the servo back and forth a bit, and it returns to the same incorrect position."

ok, that's weird. hmm. time to contact lichuan and see how good their support is?

I changed all the gains to see if one would have an effect on the offset error. Nothing. I've put a light integration loop in the cia402.conf file. That solves the problem. I don't like it. I would appreciate hearing from anyone running these amps. If you have this issue or not. Thanks.

Interesting.

I've sent an email. We'll see. If anyone has a contact, please let me know.

my only contact is the sales lady
