First time autotuning… Questions
-
The default bed temperature limit is 110C. You can increase it using the M143 command.
The warning message is telling you that if there was a fault and the heater got left on at full power, it would get very hot. You might want to consider adding a thermal cutout, and/or turn the power supply voltage down a little (and then
returnretune both heaters). -

Could you elaborate a little more…

Sorry, I made a typo and it got auto corrected to 'return' instead of 'retune'.

No worries… thanks for clarifying.
