CNC Shop is designed around deterministic results and transparent technical references. Important equations, assumptions, source boundaries, and unsupported conditions are made visible rather than hidden behind an AI response.
The app works offline and requires no account. It contains no ads, analytics, telemetry, or cloud-sync requirement.
Technical reference content is controller-, software-, and source-specific where applicable. CNC Shop intentionally does not guess when reliable source information is unavailable.
CNC Shop is an independently developed JD Tech & Solutions product. References to manufacturers, controllers, standards, or software products identify technical applicability only and do not imply sponsorship, affiliation, certification, or endorsement.
Always verify your specific machine, controller, installed options, probing software, tooling, workholding, offsets, and approved shop procedures before applying programming or machining information on equipment.
