Everything was going fine and now my z-axis seems to not want to retract during the print. I am using the dewalt and the kit from the site. In manual control the z-axis will go up and down, but while running the nc file it doesnt ever retract going further and further into the wood. Not sure what to do. I am going to try replacing the stepper driver for the z axis first.
Any suggestions or similar expiriences. Also my z-nut-lock is doing great. There is no slipping.
