P3Steel Electronics and wiring
The recommended electronics for the P3Steel is the ubiquitous Arduino Mega 2560 + RAMPS 1.4 combination, used in exactly the same way as in many other Prusa i3 derived 3D printers, but any controller complying to RIS 1a (we want heated bed support) will work.
The Arduino Mega 2560 + RAMPS 1.4 + A4988 drivers + 80mm fan as used in the P3Steel make for a neat stack and this combination is very well documented in this wiki:
