Am planning on sticking to timing belts as much as possible but downside is reduction is not easy hence more reliance on microstepping
The a4983 stepper driver has 3 logic inputs to choose from full to 1/16 step' so I've wired spst switches to a 20 key encoder and I thus switch from 1/16 to half step for slew
Torque needs to be tested
The mcu approach would be better as acceleration and deceleration can be incorporated
Will post progress
I bought a digital compass so hopefully polar alignment should be close enough
Mount is a home built fork for a newt
