The hardware it's the same as the Prusa 3d printer.

Arduino Mega + Ramps 1.4 + Marlin firmware.

Due to the size of the machine I had to use stepper motors larger than the Nema 17 for which the Ramps 1.4 plate (large format Nema 24) was designed. For this reason I have had to replace the drivers of the stepper motors with more powerful ones.
