Interesting.... but I don't understand why you would want to move all that mass around and not just put the heads in a bigger frame ?
Cut op the object and send those (separate) objects to the cura engine. Makes it a lot easier to debug things.

It's definitely true that you don't want to move the mass, but the concept of this project is about comibining multiple printers, so that the printing time decreases. Therefor it wouldn't be efficient to make a bigger printer, that would take more time to print each section instead of dubbeling the production by added extra printers.
Cut op the object and send those (separate) objects to the cura engine. Makes it a lot easier to debug things.
Right now we are thinking of a way to slice the object into parts, genarate G-code for it and then putting the different G-codes together in the right order. We are probably going to have to write a plugin that sorts these different G-codes.
But to create more strenght to the object, we want to have a little overlaps between the different layers, to make a masonry like structure.
By turning the pattern each layer this should suffice, but makes creating the G-code more complicated. I don't know if this is done before, but we're not that skilled in programming/combining G-code, so if anyone has some good ideas: they are more than welcome!
You only need a little bit of overlap; Just about the same as you have with 'normal' wall/ infill overlap (about 15%). If you ensure that the walls between the objects are not straight but have a shape with some noise, you can improve the bind between the objects.

Is your x axis straight and stiff enough for the weight of the two printers? (Is that 80mm linear rail?) You might want to run a Z-probe at various points along the axis. With the flipped over configuration you unfortunately can't do software leveling of the individual heads.

Yes and no...
The overlap will 'weld' the object together, with pla it works really well, but the adhesion between layers and also between parts is many times not as strong as the layer. Especially with other materials [ABS, PC] or fiber inserted materials [markforged] you would like to see a more integrated layering strategy.

[this is the 3rd time I challenge students from TUDelft to print larger by combining multiple fast/accurate XY frames with a slow XYZ frame to speed up production, but keep de resolution. Ther whole project is only 6(!!) weeks. See also the project form 2 years ago: http://kamermaker2013.weblog.tudelft.nl/]

That looks like an interesting project
thanks for sharing, i hope this will work or else be useful for your studies and experience.
Please share as much as possible of your project there are a lot of people here with probably usefull knowledge for you
