Actually looking at the design itself I have quite a few qestions concerning manufacturing and assembly. I understand that this is still in development but still.
My first job as an engineer 25 years ago was designing factory automation machinery eiter as a mechanical designer or later as an application engineer.
1. How are you going to get the profiles cut so that they really are going to assemble perpendicularly ? Are the ends going to be macnined ot is this going to be laser cut which should mosty take care of the issue ?
2. The guide rails for the linear bearing blocks are screwed directly onto the relatively thin-wall profile. A design practice I've often seen is that a piece of plate steel is intermittend-welded onto the profile and then milled over to get a very flat surface for assembling the rails.
3. The way it is designed right now you cannot get these 8 screws assembled, unless you laser cut or drill access holes for the screws to pass through. Even with access holes you'll be blind assembling these screws through an 80x80 profile and have to hit the thread in the "Querwelle" pretty accurately for the screw to get a hold of it. BTW I'd call this an "Achse" not a "Welle" because they are going to be mostly static. The Querwellen are free to pivot and shift, mosly without any restraint. This will be a PITA (Pain In The ...) to assemble if you don;t take proper precaution 😉
Also, util the screws ar mosthy tightened the profiles will shift in all sorts of directions, not making assembly any easier.
