Procedures

Step-by-step operations for the G1 pellet printer.

First boot and setup

First boot checklist — physical setup, WiFi, bed leveling, Z offset, Rotation Volume
Electrical connections and first boot — see First boot checklist
Initial calibration — see First boot checklist + Rotation Volume calibration
G1OS installation — flash G1OS onto the Raspberry Pi SD card
Migration to new Configurator — update GingerConfigs, initialize printer with serial number

Loading pellets — how to fill the hopper, mixing recycled material, pre-checks
Material change and purge — when to purge, light vs full purge, color change
Starting the dryer — temperature settings, loading pellets, what to do if it doesn’t start
Firmware restart — reload Klipper config without rebooting the Pi; also via console (FIRMWARE_RESTART)

Z offset and first layer
Rotation Volume calibration
Pressure Advance tuning — PA 0.3 / smooth_time 0.5 for 3mm nozzle; FGF-specific tuning
PID tuning — calibrate heater PID per zone via Mainsail console, run with fans on

Hopper cleaning — remove dust/fines/color residue, clean sensor, when to do it
Nozzle replacement — CHANGE_NOZZLE macro, PTFE tape (3 wraps), sizes 1/1.8/3/5/8 mm
Belt tensioning — see Belt and chain mechanical issues
Lubricating linear rails — when and how to oil rail carriages to prevent friction and layer shifts
Transporting the G1 — disassembly order, packing, what to recalibrate after reassembly (~1 hour)

SD card replacement — see G1OS installation
Temperature sensor reassembly (see Temperature sensor disconnected)
Barrel clog purging procedure
Heater cartridge replacement — remove motor, access barrel, slide out cartridge, PID tune after

Ginger Slicer overview — official slicer guide and workflow
Ginger Slicer first install — download, install, connect to printer, import OrcaSlicer profiles
Grasshopper slicer basics — non-planar G-code, Curve to Polyline, clearance rules
Creating a material profile — temperature, Rotation Volume, MVS, SmoothFlow, step-by-step
Mainsail dashboard basics — navigate g1os.local, Update Manager, heightmap, logs, reboot options
Klipper firmware update — update Klipper and all G1OS components via Update Manager
