I’m having issues with my test cuts. I’m using the post processor I found on this site, which seems to work well with the exception of the z-axis. Whenever the z position drops below zero (essentially to start cutting) the motor stops working. The repetier software shows that the router made the movement but it doesn’t actually happen. If the movements are above zero it will work fine. I don’t know if its a repetier problem or a gcode problem. Does anyone have any ideas on what my problem is?
