Just finished building and all looking very hopeful on the commissioning front EXCEPT I can't get the bed to warm up at all :(
If I send an M105 code in a monitor window I get: ok T:27.7 B:-39.7 I am presuming the t is for hot end temp and the b is for bed temp? I therefore guessed this mean't my bed thermistor was not connected (dodgy crimp or similar) but rechecked and finally soldered the connection to be sure. I've got no error messages showing and I can move the head in all three axis, heat up and cool down hot end no problem, just nothing happening on the bed. I get the same message with or without the thermistor or ribbon cable connected and am now out of ideas,other than sourcing a new thermistor or finding some way to (very temporarily) override the thermistor so I can check that the ribbon cable works and the bed will (some day) heat up - can anyone out there help please?
