Reducing microstepping for rigidity

[Tokoloshe (Philipp)]

@etotheipi

Given that microstepping results in dramatically lower torque

Short answer: No. This is a common misconception.

Long answer:

Carving bamboo at 100mm/sec! Another dinner plate on the portable MPCNC

That chart is completely misleading or misunderstood. A whole step sends 100% of the max current through loop A, and 0% to loop B. A half step does that same thing when it is on a full step. But at the half steps, it sends 70% of the max current through loop A and 70% through loop B (actually using more than the max current total). A quarter step does that same thing at full and half steps. But it sends 38% to one loop and 92% to the other. At 1/16th stepping, the first microstep away from …
