z-axis height control wacky
Posted: Tue Apr 17, 2018 6:22 pm
I am trying to cut a 3D model. It is an eagle above two cross baseball bats. My z-axis is starts cutting correctly, then starts cutting too deep, then starts cutting too high. I have vissually checked the gcode and it is correct usng a gcode visualizer application.
I checked the ground to the z stepper motor and it is good. I am using a Shark HD Mako special edition. One section it starts cutting down instead of up. Then another section it started cutting too high. I can’t figure out what is going on. Just a week ago I carved a similiar model and it worked just fine. The z-axis is not working at all correctly, at time it is cutting too low, almost the negative shape of what it was suspose cut, then it. starts cutting way too high.
