Z axis for roller rotation engraving

Is it possible to use the Z axis for a roller base for engraving glass cups and such?

What controller and firmware are you running?

Oooooooo, good question. GRBL is all I know but I have as far as circuit board it has a third slot labeled z axis soooo… I have the info written down at home and can get to that when I get home later

In your case you would probably swap the Y axis cable for the rotary cable.

I will give that a shot. Thanks for the heads up
