What I Learned While Upgrading To 2.2kw Water-Cooled Spindle

Hey Paul,

@paulmcevoy75

I haven’t heard of anyone having an issue with the z axis stepper? Is that a thing?

@paulmcevoy75

It doesn’t make a lot of sense to me because the the forces on the z axis from machining would seem to dwarf the load from simply holding it in the air?

there was the thread Upgrading stepper motor for 80mm Spindle in the forum some longer time ago, where most people did not really see the need to upgrade the Z stepper.

How hard is it to change out the z axis stepper?

Not difficult, you have to replace four screws by longer ones and loosen and tighten the screws of the coupler. But you got to attach the wires.
