Overview
The BTT Scylla V1 can be connected to any of the CAN-FD expansion boards produced by Duet3D (or cloned by Fysetc) as well as another STM32H743 or STM32H723 board running in expansion board mode. This includes, but is not limited to:
- Duet 3 6HC (in expansion board mode - M954)
- Duet 3 6XD (in expansion board mode - M954)
- Duet 3 Mini 5+ (in expansion board mode - M954)
- Fysetc Big Dipper (in expansion board mode - M954)
- Another STM32H723 board (in expansion board mode - M954)
- Another STM32H743 board (in expansion board mode - M954)
- Duet 3 1XD
- Duet 3 3HC
- Duet 3 1HCL
- Duet 3 1LC
- Duet 3 Distribution Board
- Sammy-C21
How to connect the board
CAN-FD only requires 2 wires to be connected between each board, CAN-H and CAN-L.
We recommend using stranded twisted wire pairs, such as those found in ethernet patch cables.
Using the Duet 3 1LC toolboard as example (and the image below), the red wire on the CAN-FD cable is the CAN-H wire and the black is the CAN-L wire. They should be connected to the two connections on the CAN-FD screw connector on the BTT Scylla V1. CAN-H is connected to CAN-H and CAN-L is connected to CAN-L.
Although the BTT Scylla V1 also provides ground on the same screw terminals, we recommend wiring the toolboard directly to the PSU.
Please ensure that you have the jumper installed as shown below if you are using this board as a mainboard or if it is the last expansion board on the CANbus.
