Changed consumables, and still have this weird chatter.
Any suggestions would be appreciated
Clean your rails, and lead screws. Check the bearings in the blocks on the Y rails.
Check to see if the torch mount is tight, not able to wiggle it around in the Z axis racket.
Check your couplers to make sure nothing is slipping.
Check all the connections going into the control box (motors)
I see you have this listed under Software? Was there something that made you think it was Software related?
My tired brain not putting it into the right category
If its only on changes of direction, its a mechanical problem. Something is loose and allowing the torch to move when it changes direction.
