How do I update my firmware to be compatible with the High Temperature Thermistor?
450°C High Temperature Thermistor
The 450°C High Temperature Thermistor works natively with Marlin 2.0, Duet/RepRapFirmware, and Klipper.
Alternatively, you can find the Resistance-Temperature (RT) table on our
High Temperature Thermistor
page and do the upgrade yourself. This
instructional video
from our friend Chris Riley from Chris' Basement can also help demonstrate the process.
Marlin 2.0
Choose Thermistor #67 in Marlin 2.0.
RepRapFirmware
Choose "Slice Engineering High-Temperature Thermistor" in the RepRapFirmware configurator.
Klipper
Use the following code when configuring your "printer.cfg" file.
sensor_type: SliceEngineering 450
Refer to documentation at
Klipper3d.org PRIOR TO USE.
300°C High Temperature Thermistor
Marlin
If you are compiling Marlin for use with the 300 °C Thermistor, make sure to choose the "100K thermistor - ATC Semitec 104NT-4-R025H42G". This is thermistor #5 in Marlin.
Duet/RepRapFirmware
If you are using the 300 °C Thermistor with Duet/RepRapFirmware, you will need to create a custom thermistor preset using the configurator. Click the R25 value for the correct heater and there will be a pop-up. Open the thermistor preset drop-down menu and select custom. Here you will input the following temperatures and resistances to obtain the correct configuration parameters.
T1 = 25 R1 = 100000
T2 = 85 R2 = 9094
T3 = 300 R3 = 82.78
If you are not using the configurator and simply editing an existing configuration file, use the following values in your M305 or M308 command.
T100000 B4680 C6.455513e-8
Refer to documentation at
marlinfw.org or
configurator.reprapfirmware.org to configure your firmware PRIOR TO USE.
Klipper
Use the following code when configuring your "printer.cfg" file.
sensor_type: ATC Semitec 104GT-2
Refer to documentation at
Klipper3d.org PRIOR TO USE.
