How we checked
bobscnc.com's own product and shop pages returned HTTP 403/timeout on every fetch attempt during verification. Specs are sourced from MellowPine's review, which reproduces BobsCNC's original spec sheet: 24x24x3.3in work area, laser-cut Baltic birch plywood chassis, Arduino Uno + GRBL 1.1 control board, up to 100in/min cutting feed with 200in/min (5,080mm/min) jog speed, and 0.002-0.004in repeatability. The machine ships without a router; it is commonly paired with a Makita RT0701C (1.25HP, 10,000-30,000 RPM), so spindle power (W) is left blank since no fixed spindle is bundled or sold by BobsCNC.
