Extrudertemp whacko.

[AndersE]

Since the new update i have been having problems with extrudertemp at startup of print.
Sometimes it just shoots to the roof (300c) .. and it starts to smoke a lot

I have jerked the wires to the thermistor but there does not seem to be any problem.
And when i get it to start printing there is no problem the print through.

I just happens sometimes when pressing "begin print"

Manual setting always work.

Or could it be that the thermistor is about to give up?

Sounds like a hardware or electronics issue.

Just go be sure, open up your gcode files in a text editor. Unless you see a command like "M104 S300" then it isn't the software's fault.
