XL hot end wont get past 170 - still brand new
I'm confused. Got my Prusa XL setup, and got literally (3) prints out. Ran out of filament and had a minor issue with getting it to reload, as it claimed that there was still filament in the sensor. Left it for a few days, and finally got back to it. Set it to heat to PLA, and it never gets beyond 170. It bounces at 169-170 and stays there. At first I would think that this is a thermistor issue, but literally (3) prints and zero fails. Why would I have a fail like this already? I understand when we get into hundreds or thousands of hours of printing, but this!?!
Any clues appreciated.

Could it be the Printer settings, Custom Gcode>Start Gcode?
M104 T0 S{((filament_notes[0]=~/.*HT_MBL10.*/) ? (first_layer_temperature[0] - 10) : (filament_type[0] == "PC" or filament_type[0] == "PA") ? (first_layer_temperature[0] - 25) : (filament_type[0] == "FLEX") ? 210 : (filament_type[0]=~/.*PET.*/) ? 175 : 170)} ; set extruder temp for bed levelingM109 T0 R{((filament_notes[0]=~/.*HT_MBL10.*/) ? (first_layer_temperature[0] - 10) : (filament_type[0] == "PC" or filament_type[0] == "PA") ? (first_layer_temperature[0] - 25) : (filament_type[0] == "FLEX") ? 210 : (filament_type[0]=~/.*PET.*/) ? 175 : 170)} ; wait for temp
I believe that translates to Do a two stage heat up.
Heat to 170C, run Mesh Bed levelling, Then heat to normal first layer temperature and continue...
the Mini has been doing this for years...

Don't forget you have two sensors per filament - if the end of the filament overcooked during the run-out you might have a string left behind in the nextruder sensor.
Cheerio,

Nope. Not using GCODE. Just using the Front Display using "PREHEAT PLA"

I assume that there is a YouTube video or similar on how to check this? The Nextruder is a new concept to me, and looks like a magic-black-box.
