CoreXY IDEX?

[nhfoley]

Hey -

I'd like to build a "CoreXYUV" machine: two independent CoreXY gantries which share the XY plane. I have the mechanical and electrical design resolved, now making sure I can set it up in firmware.

Reading through the steps of this article on setting up a Cartesian IDEX machine, it seems like I could just follow these instructions while adding a few extra V commands where needed?

Has anyone done this and/or does anyone foresee reasons that it won't work?

Thanks!

@nhfoley
Compared to a single gantry/toolchanger system your frame will have a much bigger footprint. Building it with same rigidity is the only challenge I see.
All other aspects are manageable.
We will see those multitool printers more often in the future, when firmware is ready to print two or more gcode-streams at the same time.
@dc42 is it planned to allow all of them to work on the same part, too?

@nhfoley several users have made CoreXY IDEX machines running RRF. RRF has two predefined kinematics for them already: CoreXYU and CoreXYUV. Any other Core IDEX kinematics is also supported, because as long as the motion of each axis is a linear function of the positions of one or more motors, you just need to set the correct movement matrix in the M669 command.

@dc42 Seems like this is less of a fringe concept than I feared. I will push forward. Thanks for the industry-leading control system, as always!
