Steps
POST /printer/gcode/script with {"script": "G28"} to run one or more newline-separated G-code commands; the call blocks until completion or error.
POST /printer/print/start?filename=<file> to begin printing a previously uploaded gcode file (path relative to the gcode folder).
POST /printer/print/pause, /printer/print/resume, and /printer/print/cancel to control an active job.
GET /printer/gcode/help to list registered extended G-code command descriptions before sending custom macros.
Known gotchas
Sending M112 (emergency stop) through /printer/gcode/script queues it after prior commands; use POST /printer/emergency_stop instead for an immediate halt.
The gcode/help list is not exhaustive — many built-in commands like G1 or G28 have no registered description.
