And that is how I've composed the hal files here, even for the one simple software stepper running the teeny hf mill. But do I have all the intermediary stuff in the correct order? I think I do, but no way to certify that I have. And that may be impinging on the speed I can move, or on following errors. The hf mill has no spindle encoder, so I can't thread on it, and its 200 watt motor doesn't have the power anyway. Where it really stars is doing edm, Its done several parts for the Sheldon doing edm to cut slots for compression fittings. Works well but really dirty using k2 for dielectric fluid but actually works well using distilled water too, cutting faster with the water I believe. I have a 400 watt motor that came off TLM when I put the 1hp motor on it, and someday I'll strip that box off the top, and make a 3 speed belt drive using the 400 watt motor, which will make room for an encoder. Someday. Need to find my round tuit again. :) I did order a 1x2 foot sheet of .500 thick alu, ostensibly to make a new apron for the Sheldon, moving the Z nut an inch to the right and relocating new gain pushbuttons for the jog dials to make them more comfortable to push. That will make good stock for a 3 speed belt shifting drive. But I'm still waiting for the new master-rt with the fixed function keys. ??? Andy said the buildbot was done 10 minutes after my previous post on that most of a week ago, but synaptic hasn't offered it as an update to the x86 machines yet. The pi & Sheldon, with a slightly older version, works well. Thanks all. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
