hey people, im not really sure whats going on here, i just upgraded my extruder, have powered back on and changed the config under extruder, gone to do a test print and i get this error message
i cant really make heads or tails out of the log either but nothing is different other than the extruder motor and gears. i cant see how they can be connected so im at a loss
i tried changing the fan to a newer one… double checked the jumper on the canboard and at least to me, everything is right on a hardware side
have also tried using an older config just to rule that out.

It’s your START_PRINT macro, your part cooling fan isn’t called “Fan”

	{% endif %}
	
	SET_FAN_SPEED **FAN=Fan** SPEED=1
	SET_FAN_SPEED FAN=Hotend SPEED=1
	SET_DISPLAY_TEXT MSG="Hotend: 150c"
	M109 S150
	SET_DISPLAY_TEXT MSG="QGL"
	STATUS_LEVELING
	quad_gantry_level
	G28 Z

Use M106 instead and it should work “M106 S1”
