That reduces the positional accuracy to 39 positions per rev, or to 9.2307692307692307692 degrees per step. For threading, that could begin to affect the quality of the threads I would think. Not tested of course. To maintain the scale, would that not also require resetting encoder.0.position-scale to 39.00 from its current 4x or 156.00 value? My teeny wheel has 39 slots. Thanks Andy.
