BigTreeTech EBB42 CAN V1.2 for Klipper Expansion

If you’ve caught the modding bug like us, you can’t resist the opportunity to figure out how things work, so that you can make them work better. Makers eager to upgrade their printers quickly realise the potential of a powerful CAN bus connection, which you can use to install Klipper onto your 3D printer. Klipper, a popular open-source firmware, has revolutionized the 3D printing world with its ability to offload complex calculations to a single-board computer like the Raspberry Pi, enhancing print speeds and quality. With Klipper’s rising popularity, Makers have found ways of expanding their mainboards with this firmware using breakout boards and CAN-bus modules. The BigTreeTech EBB42 CAN V1.2 serves as a crucial component in this upgrade process, acting as a nozzle adapter board designed specifically to drive a full-sized Nema 17 or 42 stepper motor for the extruder.

Best Features of the EBB42 CAN V1.2 Nozzle Adapter Board

The EBB42 CAN V1.2 nozzle adapter board is designed with a slew of features that streamline installation for your 3D printer mainboards, like the Octopus Pro. The EBB42 is made to pair with a BTT U2C V2.1 expansion board and a Raspberry Pi to complete your Klipper installation.

• Built-in BOOT and RESET buttons – Firmware updates via DFU mode are simplified.
• Added protection circuits – Onboard protections safeguard against overheating and current leakage, ensuring the longevity of the main control chip.
• Flexible Thermistor Configuration – Selectable pull-up resistor values for the thermistor accommodate various configurations, while anti-reverse connection protection prevents accidental damage during DIY projects. This offers compatibility with PT1000 and other setups.
• Onboard MAX31865 – The EBB42 enables versatile PT100/PT1000 support, enhancing compatibility.
• Multiple Communication Options – Additionally, the EBB42 CAN V1.2 supports communication via USB or CAN, offering flexibility in connectivity options.

Please Note: The BigTreeTech EBB42 CAN V1.2 is a nozzle adapter board for 42 stepper motor extruders, but if you need an adapter board for a 36 stepper motor, then be sure to check out our BigTreeTech EBB36 CAN V1.2.

As one of the rising stars in the world of 3D Printer Component Research and Development, BigTreeTech have certainly hit the ground running, entering the market in 2015 and spending their early stages primarily learning, researching, testing and developing, before producing some truly impressive results. From simple but effective upgrades to standard parts, all the way through to completely custom parts that no other brand offered at the time, BigTreeTech now have an incredibly diverse range, with almost no area of 3D Printing being left out.

Some of BigTreeTech’s most notable additions to the world of 3D Printing include the SKR Motherboard Range for numerous different 3D Printer models, the awesome TFT Touch Display Range with fancy features like dual-mode operation, as well as their very impressive Stepper Driver Range that cater to all tastes and preferences under the sun. And of course, to top it all off, BigTreeTech also have a sister company named BIQU, and we must admit that they have been producing some pretty impressive (and low price) 3D Printers, with the BIQU B1 possibly becoming a new rival to the Ender 3.

Of course, it’s easy to see that BigTreeTech are modern masters of 3D Printing R&D, and while we do still have a lot of different parts that we want to test out from them, so far we’ve been extremely happy with what they’re capable of producing – all while fitting into same kind of hobbyist budget that they used to operate on as Makers and Tinkerers themselves.
