How to reduce microstepping?
So I am using Repetier Firmware 0.91 with Ramps 1.4 and DRV8825 motor drivers. I was using 1/32 microstepping up to now and had a value of 160 for the x and y steps per mm (using 20 tooth GT2 pulleys, 2mm pitch, 1,8° motor).
For various reasons I want to switch to 1/16 microstepping now. I reconfigured the jumpers (single jumper on MS3) and modified the steps per mm to 80 (formula is here)
However, now the axis moves just 50% of the requested value (ex. 50mm instead of 100).
What am I doing wrong? Should I modify anything else in the FW besides the steps per mm?
