RE: [CAD_CAM_EDM_DRO] Re: Stepper driver question (slightly O.T.)

Before I would go to all this trouble I would check the roller's mechanics. Set
a dial indicator on end of the shaft to see if it's wandering back and forth, or
check the diameter of the roller for wear. Too much pressure on the roller can
cause the laminate to squeeze out inducing thrust loads and premature radial
wear on the bearings and shafts. Check the roller alignment adjustments to see
if they have any play in them.

But don't stop there check the opposing roller or platen roller as well. You
might be seeing the effects of another roller failing and compensating for it
with the first roller. If this is an old machine you may be reaching end of life
or in need of major overhaul.

Why would I do this? If you put this automatic adjustment where none existed
before and something is mechanically wrong then you're just postponing the
inevitable catastrophic failure that would perhaps totally trash the machine or
worse injure someone.
