Re: TMC2100 - Stepper whining

Ok, after some tweaking they now run at 1V Vref in StealthShop Mode and i´m unable to overcome the holding force by hand. Also printing with 80mm/s now works without layershifting.

I first tried them as they were shipped (in stealthchop mode) and had problems with layer shifting (but they were silent). After soldering the CFG bridges in and running them in reco...
