Title: Juddering X Axis even without running
Post by: polycut on September 24, 2015, 10:46:08 AM
Hi

My machine has started to judder back and forth when I enable my drives by pressing Reset on the Mach3 screen.

It is similar to the autotune process that is used by CS-LABS Plugin Controller for CSMIO IP/A.

The axis is only moving back and forth approximately 100 pulses of the 10000 pulse per motor rev. I can jog the axis while this is happening, but the juddering continues.

After a minute the juddering settles down and things seem OK, until I then move the axis again and juddering starts once more.

It wasn't doing this before, but I have been playing the settings a lot!

I think it may be a tuning or mach3 config problem but has anyone got ideas on where to look first?

Many thanks
Mark

That sounds like a servo tuning issue, either in the drive itself or in the IP-A plugin.
The only other thing I can think of, that it could be, is an encoder issue.
