Switching off on max temp

  • I want to configure my printer to be turned off when max temp is reached by any of my heaters. I know that there is an A parameter in M143 command but what is the difference between A1 and A2?

    Neither of them will switch off the whole machine instantly. However, option A0 will pause the print, then turn the machine off if there is no operator response within the time limit set by the M570 S parameter.
