    I have got to the final stages of powering on and the readout is telling me that I have a maxtemp error, and would like some advise on how to solve this.

    I have a sneaking suspicion that the problem came in when wiring the printer because there's a difference between how you are instructed to wire up the print head and what is in the large and small groups of cables coming out near the rumba board.

    The cables in the groups are as follows:
    Small Group
    2x left heater cable ---- HE0
    1x left Pt100 ---- furthest board from USB
    1x left fan ---- Fan1
    1x micro switch ---- x-

    Large Group
    2x right heater cable ---- HE1
    1x right Pt100 ---- not plugged in
    1x large fan ---- fan0
    1x motor ---- 4th motor port from the left
    1x IR sensor ---- z-

    Notes on the board:
    Currently the right fan is not plugged in because I didn't want to cut the connector off only to find i'd cut the wrong one. Wanted to do a test prior to doing this.

    It looks like the 3-wire connectors going into the PT100 amplifier boards are the wrong way around. Try flipping them around. The connections are marked on the boards.
