How to connect a PT100 or PT1000 to a Fly-SB2040 Pro Max V3
Overview
The Fly-SB2040 Pro Max V3 toolboards have support for PT100 and PT1000 temperature sensors.
Hardware Setup
The use of PT100 and PT1000 temperature sensors is setup using the 8 dip switches on the Fly-SB2040 Pro Max V3.
Use the image below to setup the jumpers on the 8 dip switches according to the type of PT100 or PT1000 temperature sensors you are connecting.
Config.g changes
PT100
Important: The changes shown below that are to be made to config.g assume that the toolboard uses the default CAN address of 124. If you have changed the default CAN address, make sure you change the 124 to the correct address.
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"124.max31865cs" Y"rtd-max31865" F60 R430 W#
Warning: The # in W# is the number of wires your PT100 has, which is either 2, 3 or 4 and should be changed accordingly.
Warning: Make sure you include the R430 as the Fly-RRF-36 uses a different reference resistor than expected
PT1000
To use the PT1000 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"124.max31865cs" Y"rtd-max31865" F60 R4300 W#
Warning: The # in W# is the number of wires your PT1000 has, which is either 2, 3 or 4 and should be changed accordingly.
Warning: Make sure you include the R4300 as the BTT Octopus Pro v1.0 F429 Version uses a different reference resistor than expected
