Re: [CAD_CAM_EDM_DRO] Re: Encoder circuits for parallel port hookup?

HI Abby:

Yes, if its mechanical then debounce can be the problem. Normally, encoders
are not debounced as it will
cause lost pulses. A small cap acrosss the line can help as well as a 10K
resistor to ground on each line.
Thanks,
