with a 400 slots encoder and my 5tpi screws and no reduction on the
transmission it would give me 0.0005" ressolution right?
Is there a way to multiply the encoders couts?let's say x4,that
would give me a much better resolution.
I don't like the idea of using a belt reduction,to increase
resolution,since it might intruduce backlash.(I've zerobacklash
screws).
