Hi my name s Alessandro and im trying to build a prusa i2, i have finished the structure and the problems are of software.
I used 3 different firmwares: Marlin, MarlinKimbra and Sprinter.In all of them there is the same problem: the motors doesn t work.
For me the problems could be 2:
1) on the software i wrote that i have 1 extruder and 2 thermistors (extruder + bed), but on pronterface appears an other extruder and his temperature is 0°. Probably the motors doesn t work for that.
2)the power supply (12V,400W) isn t right for my prusa i2. Maybe there isn t enough current.
Thank you so much for the answers!
P.S.
When i try (on pronterface) to move the motors they do not even make noise.
I HOPE that i wrote in the right section of the forum and in correct english.
