Got the wires - made a mistake and didn't measure pin pitch on both ends. Turns out only motor needed 2mm, control board needed 2.54mm. Made one up with a 4-pin crimp housing from Pololu.com (just a pin-friction for now, need a JST type housing for long term use) so we're off & running.
Now seeing a "mintemp" error, while we can use an IR thermoneter and see that things are definitely hot. Waiting for it to cool down and see if we have a bad thermistor.
This is ours, the Electron 3D i3 with the X-axis pieces in yellow instead of black

(not the auto bed leveling tho)
Hmm, measuring the thermistor, it jumps all over the place, vs the bed thermistor which returns a pretty solid reading. Could I have a bad thermistor? If so, is is replaceable? I don't see how one would remove it to install a new one. Do its wires feed in thru the thermistor nozzle? It feels like it just sits loose in an opening.
