@Arkadiusz said in Can't turn off input shaping:
When my printer runs it makes very jittery arc movements and printer seems to ignore jerk and acceleration settings, I got it set to 1mm/min and it still moves very rapidly. Travel jerk is so strong makes motors skip steps.
I don't think that relates to input shaping. Assuming this is happening during a print, it sounds more like the slicer is emitting Gcodes for speed, acceleration and jerk, and overriding what you're setting in config.g. Check the Gcode for M201, M203, M204 and M566 commands, usually near the beginning.
You won't get good arc movement with low jerk settings, though. Usually something in the 5 to 15mm/s gives smooth arcs.
