Inexpensive CNC Plasma Table

Last crawled date: 4 years, 3 months ago
This build is designed around steel and phenolic resin (high end lab countertop material) scrap/drops and commonly available (US) parts and fasteners. Tubes were cut on a band saw, flats on a CNC plasma table, rails on a CNC router table, holes bored in drill press, and welds with an old-school buzz box. Target is 24x24" or larger work area, no machining, no 3D printed parts, fast enough to cut very thin material at 30-40 amps, for less than $200 (not including electronics).
Motion on stainless steel dual row RM2-2RS V bearings. GT2 belts will be upgraded ASAP and only appear because intended reinforced belts will not bend backwards over the idlers.
Wood in any photos was for alignment purposes. Current STEP export in zip file. All clearances will be applied in CAM or manually and are not present in the CAD file. CAD export to Parasolid binary (included) was converted to STEP. CAD in SpaceClaim and CAM in SolidCAM, ProNest, and Aspire.
