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
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.
