Your Input would really be appreciated.
My current gantry uses electrical din rails with roller bearings for X movement. I am looking to replace them with either SBR15 (or other recommended size) rails and corresponding blocks, or linear rails and their corresponding blocks. Regardless of which is the best, the chosen ones will be mounted vertically on the face of the gantry. The gantry itself is a square birch plywood box; the span is 48” wide. The router that the chosen rails will support is a DW611 mounted using 3/4” birch plywood, i.e., Not heavy as lead, but not exactly light either. Biggest concern is stress on the bearings from either block type. I am attaching a pic of my current gantry setup.
With your recommendations, I would appreciate your thoughts on size or heft of the rail and blocks. Enjoy my CNC, but need to get some play out of it.
Thank you in advance.
