I have been printing with my Mini for while. In the last couple days, proven files were curling up off the base while printing and a few prints even slipped off the bed while printing.
After investigating what might be going on I noticed that the temperature on the bed/build plate wasn’t changing and wasn’t following the target temperature in the g-code-- so the bed would remain at ambient. Needless to say I am unable to print successfully with my Mini now.
Any suggestions on where to look next?
BTW, I noticed another thread on this forum for a mini, and the problem was root caused in that case to an open in a wire in the wiring harness to the bed…
