hello, I have a new thermistor, it is the same as the previous one, except that it has a higher maximum temperature, the previous thermistor was 260° and the new one is 350°, NTC100K. If I replace it with this new one, do I have to change anything else apart from the max_temp value on printer.cfg?

NTC100K is a complete group of termistors. so it dont have to be the identical one.

i dont know any ntc with a max temp of 260°. 260° is normally just the max temp, when your hotend has a PTFE inliner. this PTFE inliner can only work unitl 260°.

the max temp of your hotend, is in the extruder section of your config:

[extruder]
max_extrude_only_distance = 100.0
step_pin = PB4
dir_pin = PB3
enable_pin = !PC3
microsteps = 16
rotation_distance = 7.6632
nozzle_diameter = 0.400
filament_diameter = 1.750
heater_pin = PA1
sensor_type = EPCOS 100K B57560G104F
sensor_pin = PC5
control = pid
pid_kp = 27.142
pid_ki = 1.371
pid_kd = 134.351
min_temp = 0
max_temp = 260

So what parameters should I change to make everything work?

Depends, if this is really the same thermistor or not
