Duex and expansion header breakout



  • Hi, is there any way of using the Duex5 and the expansion header breakout together? I bought both for a project and I noticed now that both boards use the same duet wifi's pins for being connected. Thank you.



  • I need to use: two Z steppers, two Y steppers, two X steppers (IDEX) and two bigger steppers with external drivers for the two extruders. I have duet WIFI; the expansion header breakout board and DUEX5. Do I have any way to connect it all?



  • two Z steppers, two Y steppers, two X steppers (IDEX)

    These go on the Duet Wifi.

    two bigger steppers with external drivers for the two extruders

    These go either on the Duex5 or through the repurposed LCD port.



  • @elmoret said in Duex and expansion header breakout:

    These go on the Duet Wifi.

    Thank you for your reply. The Duet wifi has only 5 stepper drivers, so I need one more to drive the 6 steppers of the X, Y and Z axis. I was planning to take the driver from duex 5.

    Talking about the second part of your answer... I didn't know the biggest stepper drivers can be connected to the LCD port. I will investigate that. Do I need to use the expansion header breakout then? Thank you



  • I need one more to drive the 6 steppers of the X, Y and Z axis.

    No, you do not. One of the drivers supports 2 motors, look at the board.

    I didn't know the biggest stepper drivers can be connected to the LCD port. I will investigate that. Do I need to use the expansion header breakout then?

    No.



  • @elmoret Thank you man! You saved my day! Greetings from Argentina



  • I made some research and I think I will use the expansion header breakout because if I use the LCD port to connect the drivers (MA860H) it gives me 3v and I need 5v.

    In resume, I will connect the 6 X, Y and Z nema 23 2.8A to the Duet wifi, using the E0 and E1 inputs. The two extruders nema 34 will be driven through the expansion header breakout board. And the Panel Due I bought will be connected through the LCD port.

    And I will not be using the Duex 5, so I will sell it or save it for another project.

    If I am missing something please let me know.

    Thank you for the help, I really appreciate it.
