Duet 2 Wifi expansion
-
Hi, I have a Duet 2 Wifi board on my custom 3D printer and now I would like to add some extra motors (I am already using all drivers). What is the cheapest option to avoid buying a new board since this works very well and I'm happy with it. So far I found there is a mini expansion board, but it only works for Duet 3:
https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Expansion_Mini_2+However, the manual says "It may be possible to use it with other mainboards, but this is not supported". Does anyone have any experience with connecting this to a Duet 2 Wifi board or is it complete nonsense?
Many thanks!

@TheMikke duex2 and duex5 are the only expansion boards that work that have additional onboard drivers. there is one for external drivers but then you need those too

@TheMikke Unfortunately, RRF for the Duet 2 WiFi doesn't have the ability to talk to the TMC2209 drivers via the UART interface, and the Mini 2+ doesn't have an option to set the motor current using a potentiometer.
If you don't want to use a DueX5 (the DueX2 isn't produced any more), which is the easiest way to add 5 extra steppers, see here for external driver options: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting_external
