Othermill v2 by Other Machine Co (later Bantam Tools). Compact, precise desktop CNC designed for milling PCBs, plus jewelry, plastics, wax, and soft metals. Originally ~$2,200 new, now discontinued.
Tested and working: powers on, all axes jog smoothly, spindle runs clean. Includes a few end mills, blank FR-1 PCB stock, and double-sided tape to get started.
