Hi guys, i made my own cnc table router some time ago and now im try to make some cuts but i have problem with my Z axis. I made some face cutting on 650x650mm in Camworks, the program is looking fine the simulation is showing everithyng is fine but when i put my g code in Mach3 im starting the setup i find the edges on the stock the machine starts the code, the Z axis is going on the place where it should be but it goes few mm in the negative direction (some -5-7mm into the stock) and than it retracts to the position where it supposed to start the first cut -1.75mm from the top of stock. that move is not shown in the simulation is that some feature from mach3 or what im i doing wrong?
