Delta Roller

My first printer was a Voxel OX from Open Builds. Its been running for two years and I have been thinking about a large delta build. For stability I wanted no plastic parts in the frame. I have followed other builds and for this size printer most are using materials custom cut on a CNC or water jet. I could not justify a $20 13" x 13" x.125 build plate being custom cut for $150. My top and bottom plates together cost $40 and would have cost another $200 to have them professionally cut. So the basis of my build is to cut all of my materials myself and use drill jigs to give me the necessary accuracy for this build. My tools include a 12" radial arm saw, a 10" table saw, a jig saw and a scroll saw, along with a drill press and misc. hand tools. Right now I am in assembly having cut my plates and just received the v-slot materials. The total out of pocket costs for the frame material excluding freight is less than $200.
