But the fastest way to get these pins exposed is probably to join the chorus. I sing contra-bass using an old, now leaky bucket to carry the tune in, you? :)
Anyway, I copied this back to the dev list so I've now got 2 votes for it. :) > Here is a description if you want to give it a try. > > NAME: > units > > PINS: > units.prog_in (bit out, TRUE if G20 is active) > units.prog_mm (bit out, TRUE if G21 is active) > units.update_rate (float in, update rate in seconds, defaults to > 0.05s if not set) > > USAGE: > Put the "units" python file somewhere on your $PATH and make it > executable.

Still thinking on that one... Good. I'm in the middle of replacing the timedelay module with a 1 shot in my jog code, 30 seconds isn't alway long enough to get the machine where you want it, and its too long to wait before doing the touch-offs, so I'm shooting for as long as the dial is being turned by using a retriggerable, and off 2 seconds after the dial has stopped moving. But getting 10" of weeds in the back yard under control had a slightly higher priority today so I'm not ready to test it yet. :( > I hope you all have a very Happy Easter, We'll try, but the effort won't be a high visibility effort, the Missus is still pushing a walker from breaking a hip in early February, and gaining a pound or two of steel in the fix. We aren't exactly spring chickens w/o digging out a stack of calendars 77 deep for her and 82 for me so we can define which spring. :) > Kurt Thanks Kurt.
