Hi guys,

Hello, can you check how your bowden lengths are set? You can do it by pressing reset button and then holding the knob. You will enter factory reset menu by this and there is "Bowden length" as last item in menu. Confirm by pressing button and you will see bowden lengths.
If you want to exit factory reset menu, just press reset button once more.
Re: Firmware 3.1.0-RC2 for Prusa i3 MK2/S/MMU
Hi, just want to know what is the normal bowden length off MMU ?
On factory menu, bowden length are write 385mm for each one but mine aren't this length.
I was probably one of the first to receive MMU kit and mine bowden seems to be more equal to 370 mm (not exactly measured because I didn't remove them). Does someone know the length og first MMU batch ?
For this reason (I suppose it's linked), I must have decreased my retraction to 2.4 to avoid under extrusion. 😀
