Hello. I have recently been given a E 3d BOGBOX duel head extruder printer. I have been told the printer has never worked from day one since it was purchased and assembled. i hve played around with it some and have gone over the set up for the Rumba board again. So i now have the screen showing me an interface with a "Bed overheat" alarm. and since the person I got this from has been through 4 boards trying to get this to work I have decided to purchase an Duet wifi board and and a 7" screen to go with it. My problem now is i am new to 3D printing and was wondering if anyone has any good tips on to accomplish this rebuild. plus setting up the new board and screen as well. thanks

ok very good board in and is printing, poorly right now but printing.
here is my files to the E3D Big Box with single head print for now. my config.g file. this works on my unaltered E3D big box printer with the Duel wifi board.
