Unless I redesign my charge pump detector for a fast switching output, which it does not now have, and I was forced to build some hardware to get around that, which FWIW, is working fine, I do not have another project simmering on the "back burner". However, that could change in the next week, so I'll "stay tuned." The board would of course need to grow room for something to use as a Schmidt trigger in that event, or better yet a small relay to make a hard contact. One of them is triggering a 40 amp SSR, and the diagnosis is that the slow on off times of an RC circuit, were not triggering both directions of the SSR simultaneously, so I was tripping a 25 amp breaker with the inrush of a 6 amp load. So now a 50 ohm 200 watt R in series with the transformer primaries for the first 5 seconds allows the filters to be pre-charged well enough that a 20 amp breaker stays up when its turned on. A software timed soft start for the spindle power supply. Too many microfarads in its bridge and capacitor filtering didn't help the excessive inrush either. Hindsight is always 20-05 I've been told. :) OTOH, one of the things I am controling with a charge pump detector is a vacuum cleaner to suck up the cutting debris when the spindle is running, if I so wish. FWIW, I write 95% of the gcode I run. Next is probably going to be a tool changer so I can automate the use of at least 3 or 4 tools during a given job. I saw something I can probably make for that in a hossmachine video on u-tube. But it will need to be done on a swing mount that can be brought in above whatever might be projecting past it up to 5 or 6" above the table. One job is carving the pockets in a 44" strip of Mahogany for 3 of the Rockler Lid-Stay hinges, uses 3 tools with 4 tool changes I have to do by hand. Its up to me to re-position the stick for each hinge too. I suppose I could cut a passage window for the workpiece but I'd druther it just swung out of the way as long as it doesn't interfere with homeing the machine at any time. More "study" required obviously. And possibly the acquisition of more alu stock. 1/2" or so 7078T6, machines almost like cast iron but harder on the tools unless running in an oil bath to seal the oxygen out of the cut. > Regards, > Thanks Igor2.
