Obviously I need something > else yet. I seem to have it running as an A axis. However homeing is now considerable labor as I have to totally strip the ER chuck in order the get clearance to home the beast. This way it has to pass over the A to home X and Y The idea here is to mount a 2" solid cbn disk 50 thou thick, as high in the chuck as I can get it, meaning the motor clamps have to be loosened and the motor slid up 3/4", running a g2 arc in G19 mode, and between the g2 and the A motion in synch, sharpen an HSS lathe tool, hopefully with a tiny radius on the tip. But I'm tuckered for the night so tomorrow is test day. A very cautious test as the solid cbn disks are both fragile and costly at around $110/copy. gcode attached if somebody else wants to try it. Be my guest. Feedback welcomed. Thank you. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
