I’ve been happily printing away on my TAZ for the last two weeks or so with no issues at all (other than needing to level the bed & reset the Z-home to get the height just right).
Over the weekend, I noticed that my heated bed can no longer get up to 110C. I’ve been able to get it up to temp in about 13 minutes until two days ago. I just tried it again this evening - going from a powered off 21C to 65C took it over 20 minutes and it seems to have stalled out around that temp based on the temperature reading in Pronterface.
If I put my hand above the glass plate of the bed, it feels like it’s much closer to 110C than 65C, but I don’t have an accurate way to check it. I did print with PLA & ABS though and this definitely feels more than 5C hotter than the 60C setting I was using for the PLA. The wiring to the heater and the thermistor look fine as far as I can tell.
Has anyone else experienced this issue? Any ideas of things to check to troubleshoot?
