[mava70]

Hello i have a prusa i3 b with gt2560 broken I would like to know if I can buy a standard mega 2560 + ramps 1.4 flash prusa b 2560 firmware and swap cables : it work witout software/hardware modification? I don't like that much this gt2560 too many problems.

i'm afraid that you need to buy cables for ramps1.4+maga 2560 because some of GT2560 cable do not fit to ramps 1.4.you also need a lcd adapter.
As for firmware,just burn the firmware for ramps 1.4

Hi Eric,

thank you, by watching picture it seems only power cable and fan cable is different. isn't it? Are Termistors compatibile?
