Print Head not heating (3 replies)

Hey,

I've had this working before, until I snapped the thermistor when re-soldering it a few weeks ago. I've now bought a new thermistor, but after soldering it all back together the print head now seems to not heat up.

Pretty sure the thermistor isn't working properly wither though as a soldering iron doesn't make the temp change....

I've put the multimeter over the board pins with the heater turned on & I'm not getting a reading. I've also tried it after using wires with croc clips on the end to make sure it isn't my soldering... still no juice.

Any ideas why the print head wouldn't heat??

Thanks
