Know before you buy
The TMC2660 drivers are designed for high-precision motion control and are significantly quieter than standard drivers. They support up to 256 microstepping, which results in smoother motor movement and reduced vibration during 3D printing.
Yes. The board features an integrated web interface that allows you to control your printer, monitor progress, and update firmware directly from a web browser on your computer, tablet, or smartphone.
Yes, the board is versatile enough to support both 3D printers and CNC machines. Its robust 32-bit processing and high-current capacity make it capable of handling the specific motion and power requirements of both platforms.
The Duet 2 WiFi is highly expandable and can support up to 7 extruders. This makes it a strong choice for complex setups requiring multiple materials or specialized tool-changing configurations.
The board includes the necessary Molex-compatible plugs and ferrules to get you started. However, you will still need to provide your own wiring and ensure you have the appropriate crimping tools for a secure installation.
The bed heater channel is rated for 18A. This high-current capacity allows for faster heating times and reliable performance, even with larger or more demanding heated beds.
