Stepper noise with mesa on new install

Hmm, I just re-read the spec. Maybe 24 would have been a better choice. Easy test. I have a programable power supply.

If you get random "thumps" on all moving axis, that is possibly a latency issue.
One thing that may help is to set the DPLL sample time earlier, that is, change:

setp hm2_7i76e.0.dpll.01.timer-us -50

to

setp hm2_7i76e.0.dpll.01.timer-us -200
 

I saw that on another thread. Can you remind me where to set that? I assume it's the mesa tool but I don't recall its name.

Its in your hal file

Perfect! Smooth as glass. Is there a place for that in pncconf or do I need to re-edit the hal file for each change?

I'll have to look at the initial offset after Home. I'm thinking that may be a cockpit error on my part. All I'm doing is homing the machine and entering g0 x4... Perhaps I'm missing something. I'll look in the morning. Thanks for your help!
