BTT 3m CAN Bus Cable

Original BigTreeTech CAN bus cable for clean Klipper toolhead wiring. This 3m BTT CAN cable is the plug-and-route harness used with BTT CAN toolhead setups, especially StealthBurner-style EBB SB2209/SB2240 installs.

Why use this over building a harness from scratch?

• Pre-terminated BTT CAN cable: sold by BigTreeTech as the “Only CAN Cable” option for the EBB SB2209/SB2240 CAN/USB StealthBurner product family.
• 3m length: enough reach for most enclosed Voron-style motion paths without splicing short leads.
• Cleaner toolhead wiring: routes CAN communication and toolhead power through one dedicated cable path instead of a large bundle of individual wires.

Fitment and pairing

Use this with a CAN toolhead board such as the BTT EBB SB2240 CAN V1.0 and a host-side CAN adapter such as the U2C CAN Interface Board. If you prefer cutting and terminating your own umbilical, compare it with Igus Chainflex® CF113-007-D sold by the foot.

Gotchas

• This is the cable only; it does not include a toolhead board, U2C adapter, CAN terminator, or printer-side mount hardware.
• Confirm your board-side connector and pinout before powering the toolhead. CAN wiring mistakes can damage electronics.
• For EBB36/EBB42 or non-StealthBurner layouts, check connector compatibility before assuming it is drop-in.
