General Mach Discussion / true spindle speed
« on: October 22, 2010, 09:33:01 AM »
Hi,
I am trying to confic a small lathe to mach3 and can not get the true spindle speed/tach to register any value.
Using a C3 index card connected to pin#15, both LEDs lit
Using a single slot index wheel (do not have dimensions here but was configured per the mach user guide)
Index line in ports and pins checked; port 1, pin 15
Active low checked/unchecked with no difference
Spindle start and speed control are manual
What am I missing ???
Thanks for any help,
Pat
