How to connect a PT100 or PT1000 to a BTT Kraken
Overview
The has support for two x 2 wire and 4 wire PT100 and PT1000.
Board Setup
The has a series of dip switches that must be set when using 2 and 4 wire PT100 and PT1000.
The dip switches should be set as shown in the table below.
Config.g changes
PT100
To use the PT100 on your hotend, use the following code in config.g If you are in a country where the mains frequency is 50Hz, change the F60 to F50 (if you don’t know, look here)
M308 S1 P"PC_9" Y"rtd-max31865" F60 R430
Warning: Make sure you include the R430 as the BTT Kraken uses a different reference resistor than expected
