Why does my Ender 5 Pro bed stops heating 10 °C below the set point After a long battle with SKR Mini v2, TFT35 and BLTouch and creating the right firmware. I thought I was through it all and ready to start printing again after finally being able to set the Z offset and auto level the bed. My printer has other thoughts. Now my bed temperature will only heat up to 10 °C below the set point temperature and after a few minutes it starts beeping and says this on the screen &quot;Heating Failed: Bed Printer Halted, Please Reset&quot;. As an example, set it to 60 °C, it will get up to 50 °C normally and stop at 50 °C.
Anyone gone through this? I'm sure there is some setting in the firmware that I have missed up. I'm hoping someone can educate me on my mistake.
Searching the error message &quot;Heating Failed: Bed Printer Halted, Please Reset&quot; seems to indicate that the bed heater is timing out from not reaching temperature.

If you measure the voltage applied to the bed heater before the error message, does the voltage stay at Max.; i.e. 12V for a 12V bed heater?  Or, does the voltage stay constant?

If you raise the target bed temperature, does is still error out at stop at 50 °C?

Since you only indicate changing firmware, we would assume the bed heater is the same as when previously working.  Is this true?

Is the resistance of the bed heater a few ohms and not megaohms?
