Hi All,
Doing some more research, I reworked the belt layout based on how duet firmware can support an IDEX setup in corexy format, which seems to be corexyu. I've added the belt connection points to the extruders in the CAD design. I've also made it more clear on the diagram how the belts route. Can someone please confirm this will work as designed?
