I just bought the metal for a new 20" x 36" build. I am looking at using 1" solid, hardened rails from McMaster and matching ball bearing trucks. Will these be thick enough to support the gantry over the 36" length?
What would be the recomended size for the 20" axis?
The frame will be the usual 80/20 with 1/2" thick x 5" high endplates. The gantry will be 1/2 plate and 80/20. The Z will be milled from billet.
If I need to go to supported rails I will or will use thicker round rail if it is cheaper.
Does anyone recomend a good source for a C3 or better ball screw and nut assembly they would be the correct size for this build?
I will be using my Haas VF-2ss to make the parts on. Picking out the correct screws rails and bearings is the only issue to work out.
Thanks in advance for any info.
