Hi,this is not documented but it's a fact. Pololu's DRV8825 are coming definitely with the CW increase; GeeeTec and other Chinese clones increase CCW. Of course the Chinese clones don't come with documentation ...But you can read about the different behaviour in the Arduino forum (https://forum.arduino.cc).Another source:https://www.amazon.co.uk/StepStick-DRV8825-Stepper...Scroll down to the review part, where a buyer writes:"Good, cheap stepper drivers. Just make sure you calibrate them correctly. Counter Clockwise increases voltage. Clockwise decreases voltage."
Quote:"Contrary to normal potentiometer usage, the ones on DRV8825 are lowered by turning clock-wise"This is not correct. It very much depends on what type of drv8825 you bought. It might be ok with clones (like the ones from GeeeTech), but if you are using an original drv8825 made by Pololu, then the current will be raised clockwise.
