Help! Steppers losing steps and making a racket under slow feed..

Changing the pulse with from 0 to 5us wont make a difference as it defaults to 5us if you put 0 (I think, might be wrong).

.

No it should sat at what ever you put in. A low setting can cause problems for some drivers as they don't have time to read the pulse.

Where it affects machines the most is on spindle speed.

What concerns me is the statement "Just checked and only the X axis had the pulse width set to 0, and it was running fine, have set it to 5 now.. z and y were already set at 5"
You cannot have different values for different axis, what is set for one is set across the board - unless the latest version - which we don't use is different, perhaps I need to check.
