X axis issues

Machine: K40, Nano board

Board: LaserBoard

Firmware: Smoothie

Problem/ Question: I’m having a couple of issues since installing the new board and running lightburn. None of these issues happened when running the stock nano board and K40 whisperer.

  1. On some files my X axis will slow and “chug” along to the point of almost stopping. When it does happen, it is repeatable and consistently happens in the same area of the engraving process.
  2. I am also having an issue with my X axis wanting to skip. It seems to happen more often when I am experiencing the issue I listed above. I’ve had it jump as much as an inch or as little as a few mm.

The only config change I have made is to up the current on the Z stepper to get the lightobject Z table to work.

Any help would be great. My google skills have failed me so far!
