OneFinity Machinist (Gen 1)
~$2,500-2,800 (historical)
Pricing last checked February 2026
Our Take
The original OneFinity Machinist (and Woodworker) disrupted the hobbyist CNC market by offering ball screws and steel construction at a price point where competitors used belts or lead screws. When it launched, it was shocking: "Ball screws for $2,500? Really?" The Gen 1 machines had some growing pains (particularly with the Buildbotics controller), which hurt the early reputation. However, the core mechanical design was solid. Many users upgraded to Masso controllers and have excellent machines. The Gen 1 OneFinity proved the demand for rigid, precision machines at accessible prices. If buying used, verify controller type and condition; a Masso-equipped Gen 1 can still be a great value.

What the Community Says
Mixed but trending positive in hindsight. Early adopters faced controller frustrations. "Great hardware, mediocre controller" summed up Gen 1. Users who upgraded to Masso love their machines. The mechanical design gets consistent praise: "Built like a tank." Ball screws at this price changed expectations across the industry. Many Gen 1 owners upgraded to Gen 2 but kept their originals running. Generally: "Had potential that required some user intervention to unlock."
