If I could figure out how to install my surpluse $800 encoder I would but the way the machine is designed it's not easy. Faving done quadrature encoder work back in the late 80's with a Z80 processor and then later on with separate chips that are quadrature detectors the reality is the edge is

Yes, and an easier way to verify is to think the 60 RPM = 1 Rev. per second. So you need 60 slots per rev to give 60 Hz at 1 rev per second. But why bother making the math easy for a computer? Use however many slots gives the best data for the PID controller. That said, 60 is enough unless you
