I recently noticed a temperature error of the heating bed of my Taz5, which prevents me from printing correctly. I usually print PLA, where I set the temperature of the heating bed to 60°C - the LCD screen shows that the heating bed is heating up, and once it stops (when the LCD screen shows 60°C on the bottom), the heating bed does not actually have the 60°C. It only has heated to about 35°C - I measure it with a pyrometer. (
My conclusion was that the temperature sensor of the heating bed does not measure correctly (anymore), so I bought a new heating bed, plugged it in, set the temperature to 60°C and I still have the same problem! The screen says that it has heated up to 60°C, but the heating bed is way to cold to print on. Thats 80$ wasted.
I can now only conclude that something on the printer motherboard has stopped working, but before I replace that, I wondered if maybe someone knows a solution for my problem. Thanks
