General Mach Discussion / mach 3 spindle rpm display
« on: October 19, 2013, 03:43:05 PM »
Hello all - I have Demo R3.043.066, Sherline mill setup, Sherline/Wettroth DRO and six-sector sensor, Homann DC-04 speed control (pulse width modulation) and spindle rpm sensor interface, CNC4PC breakout boards, Win7.

Power to the hardware DRO spindle sensor is from the Homann boards.

Spindle rpm sensor wiggles the input in mach with manual motion. After trying index and "multi" inputs, many ways, I cannot get any rpm display in Mach.  Varied the debounce, active high/low, pullup/pulldown resistors, everything I could think of. I tried masking the multi sector spindle disk to one sector.

I don't see how Mach knows if the index is single or multi per revolution.

I'm a newbie, probably it is me.
