Re: Step Motors with Feedback From Sargon DRO ?

These are indeed glass scales. I think this type of encoder is very
common as Sargon is "the" cheap encoder brand. According to the
manual, the outputs are quadrature. Each axis only has five lines so
I could use the silly scope to figure out what is what. I was
thinking all I have to do is put a breakout connector before it goes
into the digital readout. Maybe throw in some TTL buffers just for
laughs. So do I just plug the encoder signal back into the EMC ?
How do I tell EMC that I am using a stepper motor instead of a servo
motor ? Or does it not matter since I am using freqmod ?

P.S. The feedrates you suggested seem to be working out.
