There has been talk of @Vince.Fab making a bolt-on kit for the Nomad I think?
I think I’m going to try it though. I’ll just go with ballscrews for now I think and only put linear rails on the Z-axis.
I think linear rails for the X and Y axes would work but I think you’d want to add some more material, not just use the backboard. The backboard is only ~6mm thick and has to replace some of the rigidity of the 20mm steel rods.
I’m really conflicted about the Nomad 3 though. On the one hand, it’ll be great that it exists but on the other hand it really sucks that there’s no upgrade path.
