We've recently purchased a Smithy 622 mini-mill, and i'm currently working on getting it setup with Mach and a 13" touchscreen. X,Y,Z all configured fine, motion is very nice and repeatable.
I've gone through the mach quick start tutorial, and the larger support document, and i havn't quite gotten the spindle under control. Any help appreciated.
controller board is a PMDX-110 (combination 132&106)
LPT pins for spindle:
pin 14 > spindle motor direction signal from PC
pin 16 > spindle speed as PWM signal from PC
Mach setup stuffs:::::
When i hit the toggle spindle button in mach, the spindle turns on and hits full speed (3500rpm), hit the toggle spindle button again, and the spindle will reverse direction full speed (3500rpm). it won't toggle off.
I'm sure it's something simple, i just haven't been able to figure it out. Any help appreciated!
