My marlin/arduino (1.0.6) setup is not accepting adjustments from the LCD (control > motion > Esteps/mm). I put it it, it registers on the screen, then nothing changes on the next print. Change the steps again on the LCD, then the next print does change but in the wrong direction. Change steps again, then nothing. Change steps again, and then it extrudes backwards.
However, change it in Configuration.h and upload, and it works every time. Been doing this from day one. Is this normal ?
