This is almost exactly what I’ve been planning to do! And for the exact same reasons! I’m assuming your planning on bringing the two heads closer together in a late version to reduce errors?
Yeah, it would be nice to get them a little closer to reduce the bed size lost. I’m not sure how it reduces error though. I do have plenty of Y distance so I may try to figure out how to orient the hot ends front to back. I will throe up a video of it printing.
It’ll reduce error because it minimises the height difference between the two tips that is caused by slop in the bearings/carriage/mountings.
Look forward to seeing the video!
