    Afternoon all,

    Been building my company's new BigBoxPro (Hybrid), and am having a bit of a strange issue.

    Having wired everything up, I've come to the "power on check" bit of the build manual. I'm just a bit alarmed, because everything has been wired in as per the manual, but I'm getting a "MAXTEMP" error (not the "MINTEMP BED" error described). I've fitted the Volcano hotend - not that that should make any difference.

    Any ideas? I'm loath to progress and risk damaging the equipment.

    Thanks in advance!

    Double check the position of the connectors between the PT100 amps and the Rumba board. Are you absolutely sure they are on the right pins ?

    I think so! I've been triple checking against the pictures in the Wiki.

    Can't tell for sure in the photo but the 3 pin connector looks to be round the wrong way on the amp board. Can you check that end.

    Not sure that'll do it a lot of good, if you put that connector round the wrong way then the amp board is getting reverse polarity supply. One of the pins has a '1' next to it, that's +5V which is Red on that cable.

    if you look on the boar it should say the order near one of the screw holes.

    +5V is Red
    Signal is Yellow
    0V is Black
