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

Recommended Posts

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."

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
