Warning or Pause on heater failure detection
I have this Warning (I have to check my generated gcode) : "Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault"
So yes after 30 seconds in the print start, the heater is set to 1°C, I have to found why.
But I'm asking why just a warning, why don't a critical fail is not detected ?
And how can I force to stop or pause on such error ?
Please post your config.g and the gcode you're trying to print.
What does your heater graph look like?
Was the heater at temp or not?
It happen on all my prusaslicer generated gcodes, just after the start gcode, I didn't found any M104 S1 in the code.
I'll send the code tomorrow now, going to sleep right now.
But yes the gcode seems to send a heater temp to 1 just before print and the warning came later when it detect that the temp is to low to extrude, but it does not stop the print !
here the begining of one gcode file:

Try adding T0 to the start of your start gcode so that the first tool is activated. You can also add it to the end of config.g if it's not there already to have the tool activated at startup.
Also, M104 S210 ; set extruder temp sets the temp and does not wait. Use M109 instead if you want it to wait for the temp to be reached before proceeding.

It doesn't look right to me:
G10 S1; retract
@zerspaner_gerd you are certainly right, I will modify this (this is my gcodes than I uses on Marlin, I just went to Duet a few days ago...)
And btw T0 is not the solution, tested without luck.
Thanks guys, I'll post results when I could try
