Know before you buy
No, the Duet 2 WiFi features an integrated web server and WiFi module, allowing you to control your printer directly through a web browser without needing an external computer or Raspberry Pi.
Yes, the board is fully compatible with CNC machines. Its 32-bit processor and high-current stepper drivers provide the precision and power required for both FDM 3D printing and CNC milling applications.
The main board supports two extruders out of the box. However, it is designed for expandability and can support up to seven extruders total if you add external expansion boards.
Yes, the TMC2660 drivers are known for their whisper-quiet operation. They significantly reduce motor noise compared to standard 8-bit controllers, making them an excellent choice for printers kept in living spaces or offices.
The PanelDue is optional. While it provides a convenient physical interface for controlling your printer, you can manage all settings and print jobs entirely through the onboard web interface.
The bed heater channel is rated for up to 18A. This is sufficient for most standard heated beds, but ensure your power supply and wiring are rated to handle the load safely.
