New Build, CoreXY IDEX



  • I am starting to build a new printer and would like to know if RepRapFirmware will configure it to run as I hope.
    Specs

    • 460 x 420 x 650 build area
    • CoreXY configuration
    • 2 independent head
    • 2 x 2-in1 Nozzles (4 extruder drives)
    • 3 independent Z axis
    • Duet3 controller with expansion and a Pi

    My plan/Intent/Hope is to have the following

    • Fully auto levelling (3 x Z servos and level switch on the primary head)
    • 4 filaments loaded (either as 4 colour/material or as primary and reserve)
      (when in reserve Mode, the system will automatically switch to a new reel when one finishes. Because of the size of the prints I plan, I don't want to stop when a roll runs out.)
    • Option to build a single large symmetrical print with one head (or both if viable) printing central areas and both printing outer areas concurrently as well as the ability to select dual print or mirror printing.
    • additionally all standard features including a 4 zone heated bed and heated enclosure.

    My question is whether the firmware can handle this or do I need to compromise on my design?

    Thank you for your feedback.

    The only tricky part in that list is this bit:

    4 filaments loaded (either as 4 colour/material or as primary and reserve)

    (when in reserve Mode, the system will automatically switch to a new reel when one finishes. Because of the size of the prints I plan, I don't want to stop when a roll runs out.)

    That can in principle be done using a simple filament present switch (at present, not with one of the Duet3D filament monitors) using a M581 trigger to run a macro when out-of-filament is signalled, assuming you can get the mechanics of changing filament working reliably enough.

    All the rest is straightforward. The IDEX CoreXY kinematics can be CoreXYU, CoreXYUV, CoreXY+MarkForged, or any other kinematics for which the motion of each axis/carriage is a linear combination of the motion of the motors.



  • Thank you
