Heat bed temp not working. How to reconnect wire?

Hello,

New to 3D printing. I just assembled the i3 mk2 kit and finally got it calibrated and working last week.

I did my first long print yesterday and left it going overnight. All looked good before I went to bed. I woke up this morning and the model was all over the place and broken. Basically it probably became dislodged from the bed mid-print.

Today, I went to reprint it and during the preheat I noticed the heat bed temperature wasn't reading. It would stay down at between 23-25 degrees even though I could tell it was much hotter. After inspecting the machine, I could see that the heatbed cable became dislodged from the gold foil tape underneath the heatbed(I think someone else referred to this cable as a thermistor in another post).

So my question is....can I reconnect this cable? Can I just unpeel that gold tape and reconnect it by taping it back up underneath? I haven't removed the tape yet to see what is underneath it, so I'm not sure if there is more I need to do to fix. Maybe soldering?

Is there something more specific I need to do to fix it? Do I need to replace the foil tape with a specific tape that I can get in stores? Any step by step info would be greatly appreciated.

Is there something I can do to prevent this from happening again?

There is very little information about this online it seems about this subject.

Thanks,

Mike

Hi.

You have to buy "Kapton Tape", and use it to re-stick your thermistor to the bed.

Then, before print any new piece, check, while heating the bed, that the readings are correct.

There is a square piece of silver tape in the kit, is that Kapton tape?

Same thing happened to me, the sensor is not connected to the heat plate. For some reason it came off.

Thanks
