@_Djrema Hi, honored to have you here although my project ended early as a proof of concept only.

Slicers and controller firmware are just beginning to work with more than one nozzle, so it will take a while to see a working printer.
Another reason why I started the project is, the copy/mirror mode which was interesting at first. But since I own resin printers and learned their ability to mass produce parts, they are much more intriguing to me now.

Mirror mode for bigger parts would be a reason to build a #-printer, but the build-cost will explode.
