Description Reviews

Big Dipper is a combination of duet3 mini5 + and Mini 2 +. Its main control and pin allocation are completely consistent with mini5 +, and the firmware of mini5 + can be used directly. At the same time, the power supply and IO protection have been upgraded to a certain extent to make it safer. The switching between WiFi version and Ethernet version can be realized by replacing the module. WiFi supports external antenna.

Based on the good ecology of RRF firmware and the on-board 7-axis stepper controllers (7x TMC2209), the board can be easily configured for a variety of models, such as Voron series, multi z-axis models, dual x models, CNC, etc.
