First Cut!

I made the first cuts with the CNC machine! This was in the form of two lines of holes 50mm apart on the pasteboard. Two things became apparent; One, the holes aren’t 50 mm apart, more like 53mm so I need to go back and check my settings and two, the z-axis sometimes doesn’t lift if driven to0 deep into the waste-board. Further investigation shows that the z-axis motor is turning but the lead-screw is not spinning and an audible squeak is heard. Looking at the motor coupler I can see that the worm-screw again has fallen out! Time for the coupler to go.
