ah ok,
It sounds like the coordinate systems in essence are the same, they
just have a different origin, for all the other parts, it's just the
same thing, just translated and/or rotated for another part?

Yes, you should be able to select the axis that is to have
its offset changed and then enter what that coordinate
should be set to.

The step-gen won't make steps until it sees the new target. So running

yup, that's why I noticed too. I thought "touch off" would be more
like "this is (0, 0, 0)" and just hit that button once...
I guess I got lucky a few times.

I think peters solution would work just fine. You have acceleration time.
It isn't like the stepper is going to be instantly moving at to speed.
The leadshine seems to have this built in. After it doesn't see any steps
it lowers power. Once it sees steps - it raises it back up. Unknown to

Hello,
this is probably a rookie question, but sometime when I do a "Touch
Off", the Z-position indeed becomes 0, but the X and Y are not. Then
in teh axis program, it will still go to the "first" spot where it needs
to start milling, and in the drawing it fllows the correct
lines/patte
And this does things that the engineers at K&T could only dream of...
