Can anyone help me with my non working spindle rpm indicator (dro39),
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.
