IDEX Quad Extruder and Y & Z-axis' External Driver
-
Hello All!
I need help. I'm designing a 3D printer and looking at the Duet3d controller board.
First:
The 3D printer I'm making will need make use of nema 23 motors for both the Y-axis (forward and backward) and Z-axis (up and down).
For each axis stated above, two stepper motors are needed all of which having current rating more than internal drivers can handle.Second:
It will have two independent X-carriages. each carriage will be a dual extruder system.
Though the designing stage is still not complete, I will need help.
Using more extruder means having to use the duex 2 or 5. But I need the 50pin expansion to route Pulse and Direction signal wires to the 4 external drivers for the Y-axis and Z-axis.Is there a way for me to do so?
Many Thanks in advanced!

It's not hard to find Nema 23 motors that the Duet can drive directly. Choose motors with a 2.4A to 3.0A current rating. Then you can use a Duet + DueX5 to do everything. I regularly test Duets with 2.8A Nema 23 motors.
If you want to use 4 external drivers and a total of 4 extruders, there are a few ways of doing it:
- Add your own circuitry to drive 2 extruder heater mosfets from 2 of the heater pins on the expansion connector
- Or use a DueX2 which gives you the 2 extra heater outputs. You can still connect external drivers to the 3 sets of control pads for the not-present drivers on the DueX2, and 2 drivers to the CONN_LCD connector.
