Was about to get a toy- then I did some research...

20mm is the plan, but not sure yet about going full hiwin or not...

If you want the best machine then you must bite the bullet and go with Profiled linear rails. If not then you are wasting your time worrying about things like COG or plate thickness because Boyan is 100% correct that the machine is only as good as the weakest link and round rails will by far be the weakest link no matter which axis you put them on.!

It was because of you and Boyan I never used the SBR 25 rail I have and bought Hiwin's and clone hiwin's.

One day I might use them for a plasma cutter, I did buy new bearings for them they do feel "nice" but very glad I went with rail instead.

One really annoying thing about them the mounts are 46mm apart.
