I'm building a new machine that attempts to take advantage of the strength of the larger series 15 extrusions and a test of their linear slide bearings. The gantry is built up of two 3030 3x3x36" extrusions stacked that are joined together with a number of joining plates and the 1/2" side plates. The side plates of the gantry each rest on a fully supported 20mm linear bearing, which is bolted to the lower support frame.
Motivation will be through 425inoz series 23 stepper motors powered at 36v, 2 steppers per power supply. The 1.5kw water cooled spindle will be ran 3 ph. 220v via a VFD.
I'd appreciate any suggestions.
