starting to put my base together from 50x100 Misumi milled face profile, Y axis is 1100mm,
can anyone give me feed back on the pro's and cons of either mounting the rails on top of the profile or mounting on the sides (cheeks)
on top makes alignment between rails a little easier but not that side mount is impossible.
on top will raise my gantry by a bit,

what is the preferred method ?
