@deckingman What exactly do you mean by (quote) " The problem is that the motor connected to the external driver doesn't behave properly". ?
I mean that when i try to change the microstepping through :
OLD : "M350 X16 Y16 Z16 E16:16 I1"
NEW : "M350 X16 Y16 Z16 E16:2 I1"
or steps per mm through :
OLD : M92 X80.00 Y80.00 Z80.00 E292.24:141.73
NEW : M92 X80.00 Y80.00 Z80.00 E292.24:500
the motor at E1 behaves in the same way that it used to as if the changes didn't take any effect.
Setting E292.24:141.73 or E292.24:500 makes no difference at all at the distance the motor travels for a movement of 100mm
