Note that I am using the Re-Arm board from Panucatt.

Have you done an autotune?

I found the autotune on Smoothie (running on a Re-Arm) to be far better than either Marlin or Repetier, with only very small changes needed after running the autotune.

Also be aware that if you’ve sent an M500 then the PID parameters are read from the override file, not the config file. I can tell you my parameters if you like, but they’re not likely to be much use to you as you’ve probably got a different setup to me.

Hi Nebbian,
Thanks so much, the issue seems to be coming from 20A power supply, after switched the problem is not happening. I will check some more and let you know.
