Quad Extruders?
-
I'm sorry if this has been addressed already, but I didn't see it when I just tried searching. I've added a chimera and 4 bowden extruders to my printer and had originally planned on using the original Duet with the expansion board. When this latest generation came out, I was told that it could be expanded without the need for adding a second board. But I've not been able to find anything concretely stating this online. If anyone can clarify this for me, it would be much appreciated. I'm trying to build a highly capable high capacity FDM printer to go along with a smaller capacity, high detail DLP printer build. Previously, I thought the Duet w/ expansion board was the best of the best for quad extruders. Now this new board looks even more incredible. Especially so if it doesn't require the expansion board - as that's what has prevented me from being able to finish it already (I simply didn't have the budget to be able to swing it). Any and all help is greatly appreciated.

When this latest generation came out
What boards are you referring to? The current generation of Duet WiFi/Ethernet boards can drive, for example, 3 axes and 2 extruders.
To go beyond that you need to add a Duex2/5 board - I use the 5 since it is the most versatile.

@52brandon The pins are available on the expansion header. They do make a breakout board for connecting external stepper drivers to the Duet2. See: https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams
The pins are available also on the Duet 0.85, but the wiring info has been removed from the documentation wiki. The 085 has a different pin setup for the expansion header.
