firmware_resume_print
Resume 3D prints after power loss on OctoPrint/Marlin printers by restoring temperatures, Z position, and settings using M413 power-loss recovery protocol.
Instructions
Execute firmware-level print resume for OctoPrint+Marlin printers.
After a power loss or failure, this tool positions the printer at the
last known checkpoint and prepares it to resume printing. Uses Marlin
M413 power-loss recovery protocol: homes X/Y (never Z), re-heats bed
then hotend, sets Z position from checkpoint, primes the nozzle, and
restores fan/flow settings.
The printer will be positioned and ready after this call. Use
start_print with a re-sliced file (starting at the target layer) or
let the printer resume from its own recovery buffer.
Only works with OctoPrint printers running Marlin firmware. Moonraker/Klipper
printers should use Klipper's SAVE_VARIABLE system instead (not yet supported).
Args:
printer_name: Name of the printer to resume on.
job_id: The failed job's identifier (for checkpoint lookup).
z_height_mm: Z height to resume from (from checkpoint).
hotend_temp_c: Hotend temperature to restore.
bed_temp_c: Bed temperature to restore.
file_name: Original file name (for logging/tracking).
layer_number: Layer number to resume from (informational).
fan_speed_pct: Fan speed to restore (0-100).
flow_rate_pct: Flow rate multiplier to restore (default 100).
prime_length_mm: Filament to extrude for nozzle priming (mm).
z_clearance_mm: How far above the part to raise the nozzle (mm).
