A few points if you enable microstepping mode:-
- There’s a trade-off in resolution vs power, so more resolution means you get less power (torque).
- If you disable the motor (‘always power motors’ is off) then when the device is powered back on it will re-synchronise to the home position (full step position), so you will lose any microsteps that don’t coincide with the home position. This means you might get an accumulation of step errors, so just make sure you do a home sequence often (or keep motors powered).
- Obviously you need more steps to go the same distance, so the net speed will reduce. This doesn’t effect the encoder (which is the main reason speeds are what they are), so you should be able to increase the max speed to compensate.
I use 1/4 microstepping which gives me good results (but I’m using a different and more capable stepper driver).
