    Wheels or rollers for 40x40 mm t-slot extrusion?

    I can get huge amounts of 40x40 mm t-slot extrusion for less than $3 a foot, but things like bolt on rails and wheels all seem to be made for smaller extrusion.

    I want to build a very rigid frame of this stuff, using both the end connectors and angle brackets at each joint.

    I've seen a Solidoodle 2 in action and wasn't impressed by its little bit of platform wobble which caused ripples around the layer edges. I want to have the build platform supported on two sides.

    Rigidity, no movement except the parts that are supposed to move, that's what I want to have in a 3D printer.

    I recently built a motorized camera dolly with material from OpenBuilds. The extrusion is smaller than the 40X40 you are talking about, but does come in different configurations up to 20X80. I have plans of using more of it in future builds.

    Can you use regular 40mm slide blocks like usually seen on CNC routers? 40mm Linear Motion Systems: VXB Bearing : Page # 1/1

    No. This is exactly like the little 15mm square t-slot extrusion that things like MakerSlide are made to bolt to, except it's 40mm.
