Building Started and so have the modifications. (as per the post above, I wish I had a way to machine metal at the moment) (I really really wish I didn’t have the need and urge to modify my SO3, but if I am going to keep it and make it a capable machine there is one thing I need to address). This has been a real turn off - since I really want a plug n play solution that just works. (Without spending another 10K - Nomad maybe?).
As I began to assemble the base (BTW where are the assembly instructions Carbide 3d), I noticed that the bent steel supports, while nice and sturdy are not straight and the lack of cross members make things worse and even would allow the MDF base board to sag.
Once I assemble the base and placed on my 8020 frame it was evident that the frame was warped and that this would be the #1 cause for all other accuracy issues I would experience.
While it is true that we should ALWAYS plane of working surface to tram the machine, you really DO need a base that is flat and squared. This is something I leaned some time ago from my AVID CNC machine and other manufacturing methods.
PS: Carbide 3D - maybe there is an HD frame or some sort - the current frame is not what this machine wants.

I explored several options to fix this and decided that the best approach would be to make my own 8020 frame and risers that would not only make the base squared, but also make it solid. (8020 frames are extremely rigid). Also by using compatible extrusion I can hard mount it to my bench. (we will see on that).
I was inspired by another thread here, where the OP is seeking more spindle clearance.
I am thankful to have a 3D printer so for now I am making some prototypes rapidly (see what I did there?) I will post when the part is done and test fitted.
