• Hi there,

    my name is Jens, I am from Germany and I am running a German RepRap X400 3D printer from year 2013.
    Before purchasing a Duet3D controller I would like to know if someone allready has done a version for the X400. I have upgrated this printer with an E3D Hemera extruder and I am thinking about also upgrating the controls.
    My X400 is actually running with Arduino Mega 2560 and RAMPS 1.4, it has a single NEMA17 for x and z axis, but 2 counterwise rotating NEMA17 for the y axis. Further on an SD card reader and a Hitachi LCD display. Especially the Y axis causes problems with vibrations, depending on stepper motor driver, steps, etc. So it seems to be an electrical problem and not a mechanical problem (sorry I am just a mechanical engineer, not knowing too much about electronics).
    If upgrating to the Duet, two separate stepper drivers for the y axis is a must have.
    I am looking forward for any hints or experiences!
    Thank you!

    Even if someone else hasn't done the conversion, you should still be able to get it working. It's just a matter of making the right connections and then informing the firmware of what you have connected.

    These pages may help you along


    And here is an example conversion done on an Ender 3.


    For getting the right configuration, you can use the web tool to get started. https://configtool.reprapfirmware.org/Start

  • Thanks for all information, Phaedrux. From reading all of this, a Duet Maestro would fullfill my demands. I also tried to create a configuration with the web tool, but there is just one Y axis driver available. Could be the "E1" driver output configured to a second Y axis driver? This is one of the most important things I want to do with the new controll, the X400 has 2 motors for the Y axis. See attached image!
    And no, I do not want to use the z driver output to connect the 2 motors to one stepper driver.

    @JeFro said in GRR X400:

    Yes, you will need to change that manually afterwards though by editing M584 in config.g. You'll add the driver # you want to use (E1) to the Y axis.
