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)
