Hi!
Please give a link to the firmware for the 3d printer MBot Cube Dual Extruder
I have problems with printing.

What sort of problems?

Extruder first layer normally prints, the second smears a lot of squeezes out the plastic.
In replicator G I did not find the parameter responsible for the speed of the supply of plastic.
