I know nothing, job snow.
I am frankenstein'ing a large format, 3 in 1 out 3d printer.
I'm using a pyramid a1 (300x300x400mm) frame and mechanicals, choice of 2 different pc boards that can handle 3 filament feeders plus dual z axis (6 total drivers). In addition to filament run-out, auto-leveling and power out resume, I wish to add wifi.
I can wire the pcb and mechanicals together, np, open marlin in Arduino, ok,.........l
