{"id":"gcode-g19-1","model_id":"G19.1","name":"LinuxCNC G19.1 Plane Select VW","summary":"G19.1 is a LinuxCNC G-code that selects the VW plane as the current machining plane. Plane selection determines the plane used by operations such as arc motion and canned cycles. The document states that the VW plane does not support arcs.","study_notes":["G19.1 selects the VW plane.","The UV, WU and VW planes do not support arcs.","The document recommends including a plane selection in the preamble of each G-code file.","The effects of plane selection are discussed in the G2/G3 arc section and the G81-G89 canned cycle section."],"safety_notes":[],"sources":[{"url":"https://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g17-g19.1","title":"G-Codes","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":3,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"instruction","spec":{"language":"gcode","code":"G19.1","group":"Plane Select","syntax":"G19.1 - VW","parameters":[],"dialect":"LinuxCNC","related":[],"standards":[]},"url":"https://machineschema.com/instruction/gcode-g19-1","license":"https://creativecommons.org/licenses/by/4.0/"}
