Fan Voltage
The fan voltage can be set using jumpers to either 5v or 24v. See the Fan instructions for more information.
CAN Termination
The CAN termination can’t be removed from the PITB V2.0.
Initial Firmware Installation
The board that you will receive doesn’t have any firmware installed so when plugged into a computer, the board will show as an rpi drive.
Download the file called Duet3Firmware_PITBV2_0.uf2 from here.
To install the firmware, whilst holding the BOOTSEL button, plug the StrideMax Dual V2.0 into your PC and drag and drop the .uf2 file onto the rpi drive that appears. Once uploaded, remove the toolboard from the computer.
Follow the CAN Connection instructions to continue.
Updating the Toolboard Firmware
Using DWC, upload the latest firmware file to the system tab. Once uploaded, send M997 B124 and it will update (This assumes your board is the default CAN address 124, change the address in the command if necessary). The updating time (around a minute or two) is longer on RP2040 based boards so be patient.
