Re: missed keystrokes problem, back with a vengeance.
I wonder why there's so much noise. Are you using something like a
light dimmer for speed control? And what kind of noise, continuous or
spikes when events happen? If you turn on an AM radio in the vicinity
you'll probably hear your lathe noises, which might be helpful. I was
thinking lathe = induction motor with belts for gearing, but you're
probably got some nasty SCR or Thyristor causing trash. Are you doing
pwm of the lathe motor from the Pi? Optoisolators might help. Got a
schematic? I'm a ham and electronics technician with some machine
shop experience. Never attempted anything like this though.
