No experience at that Todd. But I believe I have it working. A timedelay to give the spindle time to start moving. 200 milliseconds. A retriggerable oneshot looking at the encoder to detect movement. An and2 with the oneshots out-not is in0. True if not moving. The input in1 is the timedelay. True after the timedelay, which is started my motion.spindle-on. That and2 gives a logic one out when both are true. Thats fed to a not, and the not is fed to motion.enable. Start spindle with motor power off, or backgear in neutral, 200 ms later the machine on button goes off. And spits out a motion stopped error message. Click the machine on button after reaching around a mag based dial that sits on the head for handy use as the chuck is a 5" 4 jaw, hiding even the extended lever I put on the backgear, and put it in gear, hit r and it should run the program. In the instant operation, its making a replacement block for a junk compound of this Sheldon 11x36 I bought back in early June and am doing a cnc conversion to. That block of cast in the chuck is at least 20 lbs. A measureable percentage of the whole lathes weight as its only a 7x12. But its been rebuilt here and there and almost usable as a cnc lathe. Ball screws, tapered gibs, and a compound replacement block of cast iron to replace the weeping willow compound it came with. Still needs baby sitting from time to time, and this will reduce that. Thats probably a 20+ hour job as the block is found cast. A pour plug cut off a truck wheel casting at our local casting operation. Good source of cast for a hobbyist machinist, but darned near more than my back wants to carry in one piece. But next is a skinny-dip as I have an appointment with a medicine man at a hospital/clinic about 30 miles up the superslab at 1pm. I need to see his dance & maybe do a few steps of my own before he'll renew a prescription for gabapentin that keeps me going. My back is going away, lots of pain. I don't recommend getting old, avoid it if you can. :( Take care Todd. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
