Filament gears not moving

Try to reroot the toolheadport with M1029, have a look here:

A350 3D module not detected, even after new purchase of module

Ah, stupid me, did not read the doc properly. If you go to the page I linked earlier, it is pretty clear. Here’s how it really goes: Start Luban, connect to printer Switch to the “Workspace” section of Luban In the Console section where there’s “Send command”, type M1029 E2 (case matters, captial M, capital E) and hit enter Send M500 command to save setting Power-cycle the machine → Now the setting should stick and the port re-mapping is effective. It will stay until you repeat the procedure…

Unfortunately it seems you will need a new controller…
