So I'm thinking of doing this. Moving the 8020 y axis supports to the edge just outside of the router body. Then make a 2040 frame underneath that connects at the front and back supports. Place a few 2020 cross members. Spoil board goes on top of that. That should give me 80mm more z room than the default 61mm. Lead screw and 6020 for the z would need to be extended but that's easy. Everything bigger than 61mm would have to fit within the box defined by the 8020. If I wanted more space I could also by the bigger gantry plates. (which I could also do but I have a lot of the extrusion already.) Obvious problems with this?
