I decided it was time to dirty up my machine so ran a drawing thru Estlcam into Repetier Host. Moved all 3 axes to where I wanted (0,0,0), put power to the board and router and hit print. X and Y are doing as expected, Z remains at 0. The little box in Estlcam shows the 0.5mm toolpath depth I set but no joy. I think I’ve looked at all the usual suspects I can think of so ???
Edited to add when I did the crown the Z lifted pen from paper between shapes, when I try to run a program now, X and Y behave as expected but Z remains at 0. Z moves as expected under manual control.
