I get this printer very cheap as the seller this it was the board broken , after of some search I find that the 5v power line in to the board had a sort ,I have just repair it and was working like a charm.
Due to closed source firmware that was very problematic and of course that I can’t use any filaments I wanted I converted this printer in to open source with Arduino mega-ramps board.
Here’s is some photos of the mod and some more upgrades..
