Posted · Wiring order on UM2 Heated Bed

Hi there

please could I get some advice?

I have reassembled my UM2  after a repair and have managed to put back most

connections so it turns on,  using another UM2 (extended) as reference when rewiring

But 1 wiring difference between the printer models  UM2 heated bed wires are  blue and brown

                                                                                      UM2 Extended both wires are grey

does it matter which way round blue and brown wires go when connected to the green heated bed terminal ?

if so which colored wire goes next to the X step connector?

Many thanks in advance (really don't want to blow up motherboard)

    Hi birdy100,

    It does not matter as the whole heath bed is floating. I.E. None of the two connector terminals for the heath bed are connected to ground.

    Same is true for the PT100 temp sensor on the heath bed, where the two black wires are connected.

    Thanks.

    Torgeir.
