    NEW 2X2 gantry build

    here's my new build. cut area is 26" x 26" x 4.5". I used the Xylotex stepper and driver system. I'm using Mach 3 to run it.

    The swept back design of the uprights is common on CNC routers. it is a way to reduce overall table size while maintaining full motion. If the sides were just veritcal the furthest back the x-axis could be place would be above the rear linear bearing, forcing the spindle further forward. So to maintain full table use the cutting surface would have to be longer.

    Gordon, I designed this router to make it into a kit. I used as much 8020 as the design would allow. The sides I made. The thought behind offsetting the sides was to center the router on the bearings to maximize table travel, and also try to offset the weight. No calculation was done but I'm sure a center of gravity could found. I designed this on Solid Works and will try to post some plans. As far as accuracy I've done some test parts and it seems to be within .002. The steppers and drivers came from Xylotex. The controller software is Mach3. Most of the other parts were found on Ebay. Here are some pics of a couple of test parts.Attachment 222300Attachment 222300Attachment 222302

    Nice machine.

    I like the clean simple layout of the components.

    Nice job. Simple and effective. I like what you did having the lower X-axis linear bearing on the rear side.
