Hi All,
"Anyone working on a lathe index for use with Mach would be well advised to design something that can accommodate a multi slot wheel of some kind."
Actualy you may need two disc's one for index and another used for monitoring the rpm of the the spindle. Where this is all going or end up is purely experimental and it only relates to PP use. Not much activity currently going on.
There is only a few of us randomly fooling with it and wish there were more.
I haven't tried using an encoder, in this case, just one of the channels, but maybe in the near future.
Have some 128's so that would be 256 counts on one channel and haven't tested to see how it may limit rpm readout.
You could stretch or devide the encoder pulses using op amps. Just another book to read as i haven't fooled with them in years. Depending on the encoder / 5 volt supply, you "may" need to ampify the signal to change the pin state from a high to low.
Only guessing, but, until the current code rewriting of Mach gets done, probably won't see any new SS plugin or much pressure on taking care of threading or Turn / lathe for that matter.
So don't hold your breath!
Transition periods of change seem to be llike an eternity!
