BigTreeTech

With this motherboard from Bigtreetech you can easily upgrade your 3D printer.

The RRF E3 v1.1 is equipped with a USB connection and four motor driver interfaces: XM, YM, ZAM, ZBM, EM. You can easily expand the interface to include a filament detection function, a resume printing function, BLTouch for automatic bed leveling and RGB light. In addition, you can connect the automatic shutdown module so that your 3D printer turns off automatically after the print is completed.

The mainboard has a size of 103.75mm x 75.25mm and is compatible with the Ender 3, Ender 3 Pro, Ender 5 and CR10.

The BIGTREETECH Eddy Duo is an advanced, non-contact auto-bed levelling sensor designed to improve the precision and efficiency of your 3D printer. Thanks to advanced eddy current technology, the Eddy Duo detects microscopic irregularities on the print bed, allowing for fast and accurate height adjustments and optimal first layer adhesion.

Key Features:

• Fast and accurate levelling: Levels the print bed in just 20 seconds with 0.5 µm precision, resulting in a uniform first layer and improved print results.

• Versatile connectivity: Supports both USB and CAN bus communications, allowing it to be flexibly integrated into various printer configurations.

• Lightweight Design: Weighing only 6 grams, it minimises the load on the extruder and maintains the printer's movement speed and accuracy.

• Temperature Compensation: Integrates with Klipper's temperature compensation function to keep levelling accurate and prevent temperature drift.

• Easy Installation: Designed for easy mounting on standard Voron X carriages and compatible with various 3D printer models.

The Eddy Duo is specifically designed for Klipper-based 3D printers, offering seamless integration for users seeking superior print quality and ease of use.

The Eddy Coil from Bigtreetech is a cutting-edge, non-contact, high-speed leveling tool designed specifically for Klipper. Weighing in at just 6 grams, the Eddy Coil can level your print bed in as little as 20 seconds with an impressive 0.5µm precision. Utilising millisecond-level eddy currents, it detects minute irregularities on the print bed and adjusts the height accordingly to ensure perfect leveling. Advanced temperature compensation technology guarantees consistent and precise leveling even with temperature variations. Installation is a breeze, easily fitting on the TL-Q5MC/PL-08N location within minutes. Compatible with EBB36/42 CAN, it’s ideal for DIY enthusiasts and perfectly suited for H2 series extruders and the Ender-3.
