Heat Bed stuck on

[johnfink]

Geeetech i3 / GT2560 Rev A

Any help appreciated,


I made a silly mistake and added insulation under the bed - fiberglass and foil - seemed that I shorted the bed heating by the pop and subsequent failure of the bed to heat.

I found bad fuse and changed - now the bed won't stop heating!

Thermistor is working - it will read room temp when off and climb when the printer is powered despite indicated setpoint of 0. Will also rise and fall when I touch the tip of thermistor with my finger and take it away.

Motors are still moving,

Is there some way to reset the printer that I don't know about? I tried hardware reset, reupload firmware, but no luck.


Thanks.
