Otherwise, I don't have a clue as to what is on the printer, whether it has a booloader, etc. End quote - Which screen captures? The ones from the slicing software? I assumed Marlin was the base for the printer in general and selected that from the slicing software setup menu. Quote -from screen capture you made earlier its clearly running marlin FW. Marlin 2.0 are ready configured and installed in both boards. i worked with RAMPS board on my Bethan machine, and now 2 RAMPS for my CNC and a giant printer (i call it Cartesan). trying this path on that anet board should not hurt, at worst is rejected arduino IDE request to upload FW. Melzi also is not an arduino board, but compatible and works with arduino IDE without a programmer. my Melzi board doesnt have any except for stepper drivers.

End quote - mosfets are working as hard switches (not linear mode), barely need a heatsink. RAMPS is just as bad - cheap boards, bad layout, no heatsinking. all the mechanics are there, easy and cheap.
