I built my first CNC machine (gantry style) recently and had a blast. It is great for wood and small cuts in aluminum. Now want to build something more rigid dedicated to aluminum, I'm sure you've heard this story before...
My next build is likely going to be a C style mill with a pretty small work envelope to try to achieve max rigidity.
After watching this video (ignore the title for a moment, seems to have some good advice for driving rail systems and alignment)

This has me thinking a lot about dual rail setups where one rail floats.
I've ordered some 20mm profile rails and I wanted to ask if anyone has paired one profile rail with one supported rail as the "floating" rail. This gives my old sbr16 rails a home and simplifies alignment.
