Foam Cutter

Phlatprinter-inspired foam cutter machine for light-weight tools... needle-cutter, laser, pen/marker, drag-knife, etc. Constructed with inexpensive construction materials -- 3/4" EMT, window-screen frame, 5/16" machine nuts/bolts, etc. -- and printed parts similar to MPCNC. Sized for 30" x 20" DollarTree foam board (DTFB) commonly used in RC foam aircraft construction... other sizes can be accommodated with a suitable frame.

The X-axis is belt-driven with a compact carriage that features a lead-screw driven Z-axis. The Y-axis uses rack and pinion drive... slaved tractors that engage racks affixed to the edges of a frame that carries the material being cut.
