UM3 bed doesn't stay at 0 degrees, jumps up as high as 60 degrees.

I'm trying to print with Taulman Bridge Nylon. With my last print, I had the bed turned off/set to 0 degrees in Cura 2.5, with Elmer's Spray Glue, and I was getting the best bed adhesion after 8 failed prints.

But after a few hours into it, I found that the bed was heating up randomly, causing the the bed adhesion to fail and the print lifting off. When I hit "Abort Print," the display said the bed temp was a 60 degrees!

How did this happen? And how do I prevent this?

Side note, if it helps, the bed was never at actual 0, UM3 was reading it as about 35 degrees, but it was creating great adhesion as is. And if it wasn't for the heat jumping up, I think it would have finished the print just fine, so thats not necessarily a "problem."

You can look 'under the hood' with

/temperature.html

Use the ip-address of your printer.

You will see setpoint, actual value and control value of all heaters.
