Are you planning to publish the basic CAD? Using the t-slot extrusion as you have should make it easier to build a simple enclosure, somebody in the community might end up giving it a go.
The way the X and Y motor stick out makes it a bit footprint-inefficient, which could be resolved by adding a belt and flipping the motors 180º, but at that point it’s probably becoming a bit overdesigned for its primary use case.
Yes, the CAD is coming. Just wanting to further validate the complete machine and ensure the part designs have solidified enough before sharing.
The motors sticking out is an issue. One thought i had was due to our cable management, someone could easily design a small window-cutout for the X motor to stick through as it goes back and forth. It technically wouldn’t be within the enclosure, but could allow for the machien to be almost fully enclosed.
As for the Y’s… they could also have cutouts to allow the motors to stick through the rear wall. Of course for tiling operations, it’s good to have a horizontal swinging door that could come up whenever passing-through parts are required.
