Still in the planning stages.
What count encoders will KFLOP/SNAP AMP use or are the most optimal? I have RENCO encoders on the ends of my Electro Craft DC Brush Servos. I know one of them is 1000 resolution.

Hi Marty,
Generally the higher the resolution the better until the 1 MHz limit is exceeded which is rare.
Are those 1000 pulses or 1000 quadrature counts? There is usually a factor of 4 difference.
Even if they are pulses, 3000 RPM would generate:
3000 / 60 x 4 x 1000 = 0.2 MHz

Tom, go to the files section under Marty’s Encoder. I uploaded
the spec sheet there. My model number is:
RHS21D-P1-1000-1/2-5-CA18-LD-M1-0-P

Yes those are 1000 cycle (4000 counts) per rev and should work fine to 3000 RPM and beyond.
