Re: Help! EMC problem when trying to use 4th axis to control laser

don't know anything about EMC but here are two tests to try:

1. Add a manual pause between moving A and cutting the arc, perhaps
replace laser with a pen for this test.

2. See if changing the amount A is "moved" by makes a difference.

Perhaps check that none of the axis are slaved to the A accidentally.
