275 print temp producing Err: MAXTEMP
Received, built, and printed my first 3d object ever on a brand new Prusa MK3S+ on March 9 of this year. It is now producing issues when attempting to print at 275. The only modification to the machine is a .6mm hardened steel nozzle.
Trying to get the correct print temp for some PETG Carbon Fiber.
In the video at approximately the 0:59 mark, the extruder nozzle reads 278, it jumps to 296 and trips the MAXTEMP error, and then the nozzle reads 313
278c at 0:59-
296c at 1:00-
313c at 1:00-
Research indicates that this could be a bad thermistor, I checked the wires, everything is good, clean, and new. It's also rock solid under 275. I don't know why it would be a faulty part so soon.
Other research says thermal issues were fixed with the 3.12.x version firmware.
Let me know how best to proceed.

Here's the gcode dropped into a text file-

In order to rule out any of my settings, I reverted all settings to factory defaults except the printer settings where I inserted the temp tower gcode to change the temp from 275 to 260.

RE: 275 print temp producing Err: MAXTEMP
This morning I updated the firmware to 3.12.2 on the MK3S+ and it has been able to successfully print at 275 without the repeat errors of the previous runs with my own settings and Prusa's factory prusaslicer settings at a temp of 275 for PETG CF.
This is quite unfortunate given the fact that 3.12.2 causes the printer to behave erratically between prints.
