Powerful BigTreeTech Motherboard Re-Imagined

BX’s new 32bit, 400MHz chip, is capable of more complex printing, and offers safety features like drive reverse plug protection, heating overload protection and real-time monitoring of power supply voltage to extend the durability and longevity.

Lightest Direct Extruder

The world's lightest (219g) all metal direct extruder with Ra0.4 smoothness is built to reduce inertia and clogging to its minimum for accuracy improvement. The 7:1 torque transmission ratio ensure excellent printing performance.

Double Precision Stepper Motor

Instead of a standard 1.8° stepper motor, BX uses a 0.9° motor with twice the precision. This significantly improves fineness and accuracy in terms of print quality.

Open Source & High Expandability

BX’s firmware code is open-sourced, and new firmware code updates regularly on GitHub. BX is reserving driver slots for more functional expanding.
