In response to question from @JavierHernandez-bj5hz asking where the Quad head design will be CoreXYUVAB

The current 2 head dual gantry implementation is already CoreXYUV, with AB added on for independent Z lifting.

When I move to 4 head IDEX I will be changing the kinematics of each Gantry over from CoreXY to Dual Markforged - So I guess it will be something like Double , Dual Markforged, Might be Better to call it Quad Markforged I suppose/

In terms of AXIS it will have Z0, X1,Z1,Y,X2,Z2, U1,Z3,V,U2,Z4.
Which in RRF will be XYZUVABCDEF.

Then just to add to the complication - the next phase after IDEX is 'occasionally moving bed' - which will add a additional larger Y axis movement capability - so will then be
Z0, X1,Z1,Y,X2,Z2, U1,Z3,V,U2,Z4, Y2

, Which in RRF will be XYZUVABCDEFG

Thanks David, I called it TotalPnP QuadMarkForged. I not design a 3D printer,actually I design desktop SMT (PCBA) machines. And I have some interesting ideas with this.

So, would duplicating the Dual Markforged IDEX kinematics be enough?

What do you think about using GT2 50T timing pulley instance 20T timing pulley in motors? I have been using it like this in both Y and X for years with Nema17 60mm in cartesian machine and it has worked well for me. You lose a little torque but you gain some speed, and since they are 60mm there is still enough torque to work well.
