BIGTREETECH EBB36 GEN 2 Klipper Toolboard – CAN Bus & USB
The newest version of the EBB line, the EBB36 GEN 2 can utilize both USB and CAN for communication, support higher chamber temperatures (75c), include all necessary cables (drag chain / motion rated) and include much greater protection schemes to protect the board from damage.
Drastically simplify your wiring and unlock pro-level performance with the BIGTREETECH EBB36 (NEMA 14) GEN 2 Klipper Toolboard. This essential upgrade for Klipper firmware users replaces bulky cable chains with a single, lightweight connection, moving all toolhead control directly to the extruder motor.
The EBB GEN 2 boards are the powerhouse choice for Voron, VzBot, Ender, and custom 3D printer builds, delivering the speed, reliability, and robust features modern 3D printing demands.
Why Upgrade to the EBB GEN 2 Toolboard?
The GEN 2 boards represent a complete redesign focused on one goal: bulletproof reliability. These aren’t just incremental updates, they’re built to survive the mistakes that would kill other toolboards.
Protection Everywhere. Nearly every input and output features multiple layers of protection against the most common failure modes: reverse polarity, short circuits, ESD strikes, over-current, and over-voltage. Even the mounting holes are grounded to dissipate static buildup that could reset your MCU mid-print.
Switchable Communication. Choose between CAN bus and USB-C with a single jumper (no firmware changes needed). The included adapter board handles all the signal conditioning and protection, while the passthrough port automatically adjusts to match your selection.
High-Temperature Ready. Tested up to 75°C chamber temperatures for extended operation. Perfect for printing high-temp materials like ABS, ASA, and nylon in fully enclosed printers.
Premium Cable Included. Every board ships with a shielded, drag-chain rated cable featuring proper strain relief. No more buying cables separately or dealing with broken wires.
Key Features
Circuit protection on almost every input and output to prevent damage through unintentional connection mistakes.
Switch between CAN and USB connectivity using a single jumper, and the passthrough port automatically adjusts to the new setting.
Signal boosters to ensure rock solid USB connectivity.
Tested up to 75°C chamber temperatures for long-term performance (a fan is recommended when operating above 60°C chamber temperature).
3-pin tacho fan for hotend fan failure detection.
Voltage selection (5V/24V) available for all fans.
I²C port for connection to environmental or Eddy sensors.
Thermistor dedicated to motor driver temperature sensing.
Three PWM-controllable fan outputs with short-circuit and thermal protection.
Relocated reset and boot buttons for convenient access.
Main control chip: ARM Cortex-M0+ STM32G0B1CBT6, 64MHz.
Grounded mounting holes for ESD dissipation.
