Hi,

I have a prusa i3, totally normal, y changed the arduino and update marling and recalibrate but I se something strange...

The marlin at default numbers goes right but when I push to 10mm it moves about 150mm 170mm.

I only cant make the correct moves if i change the default axis steps per unit at very very low numbers;

Original: 80,80,4000,600

My: 4.91, 6.216, 250.84, 50

Any idea? With this configuration the printer is so noisy

Your controller is something like a ramps

You configure the hardware micro stepping for the stepper drivers with 3 jumpers (most are hidden under the pololu modules)

You need to put 3 jumpers on to set 1/16th micro stepping for standard drivers.

This will also quieten down the printer.
