Non working spindle rpm indicator

[Sven_D]

Can anyone help me with my non working spindle rpm indicator (dro39), I am using a G100 with latest plugin and Mach3 v3.039.
I have a hall effect sensor going to input 1 on g100 and the input led is flashing as it should,
the index led on the diagnostic screen blinks every now and then.
I have index enabled in ports and pins and have tried active low and high,
just finished a full reload of mach3 hoping it may solve the problem, but no change.

Are you sure mach3 supports it when using the G100? I don't believe it supports threading, so it may not support the index pulse either.

Hi Gerry
Who knows what mach 3 supports with g100, info is a bit hard to get, do any other g100 users out there have rpm working?.
I wonder if I could sneak the index signal in through the printer port and bypass g100?
