Hi Phil,

Have you considered attaching some sort of a split collar clamp to the headstock? You could use it to lock shaft rotation while you tighten and loosen your accessories.

Mukanico,

I have - only last night after my post!  :thumbup:

It will have to clamp over my slots but that shouldn't be a problem.

What speed are you getting out of your hybrid stepper?

Cheers.

Phil.

"Great" minds think alike :thumbup:

For the moment I'm running the motor at 1500rpm when indexing (15rpm at the 4th axis output). But I haven't really tried to find its limit. For my needs, this speed is sufficient...

Cheers
