Thanks for the advice Jaz.
I have got the z axis to jog up and down perfect now,although I don’t know what was wrong with it.
Some of the connections weren’t looking the best so Idecided to re-wire the motors.
At this point I have managed to blow a driver by mixing thewires up (what a donkey).
I don’t have a multi meter so haven’t checked the voltage onthe step pin yet, but will do this tomorrow.
When I tested the system before I blew it up, it wouldengrave fine, when I tried to pocket or profile it just slammed straightthrough the work piece.
When I click on go to home the x and y are where they shouldbe but the z wants to be lower. Any thoughts on why this is happening?
Also does anybody know how to get the magic smoke back intothe chip on the driver board?
