This may seem like a pretty stupid question but this is my first time messing with the acramatic 2100 control on this machine and I can’t seem to figure out the routine for bringing the quill back into the retract position. Machine didn’t come with the operator manual so I’m just playing around trying to figure this control out. I pushed quill advance and it extended all the way out with the button led lit red. I pushed the quill retract button and nothing happens. Also hoping somebody could walk me through the homing procedure. First thing I did was over travel in x!
