Hi,
I received my new A30M this week, after a proper setting up following geeetech docs, videos ect. I tried to print (trought repetier host)a simple calibration cube in two colours without success. I think is a matter of Extruder steps/mm calibration. however, I noticed that in the firmware only E0 steps can be modified.
So, now i'm wondering how or if its possible to calibrate also E1.

Thanks in advance for any hint.

Hello, if you want to calibrate the extruder, you can use the smartto firmware modification tool, as follows:
