Pre heat fail

I wanted to use my old printer as a heating surface for some science experiments, but when I press pre heat and enter a target temp, the current temperature is correct, but target temp shows 0.

Is there a fix?

    What kind of printer is it?  Some Marlin preheat features have a timeout.  Some don't.

     

    By the way, the printer is a great controlled heat box.  You can rise bread (i've done that), make yogurt, dry out filament, dry out dessicant, and many other things that need an accurate temperature.

     

    Cover the "experiment" with thick amounts of towels or blankets.

    It's a ctc i3, runs on reprap, and thanks for the advice!

    Have you tried turning it on by sending a gcode command?  You could also create a 1 line gcode file in Notepad  M104 Stt (where "ttt" would be your target temp) and print it.

    Maybe follow that with an M1 (or M0?) which should pause the print.  If it prints the gcode and gets to the end, some firmwares will turn everything off after they finish "printing".
