Help to flash pcb as 3 in 1 out 3d printer

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

You will probably get more useful help on the RepRap Forum that is dedicated to 3D printing.


I'll look into that. Ty. Didn't know where to begin, but ty.
