gMax 1.5 Plus

The gMax 1.5 Plus is an FDM 3D printer from gcreate with a 16 x 16 x 12 mm build volume.

Calibration

• Verify the machine state before any calibration print.

Action: Power on the printer, inspect the frame, and confirm that the gantry is square, belts are tensioned evenly, the build plate is clean, and the nozzle is free of cooked filament. If the printer has dual extruders, move both carriages by hand only when the machine is off and the steppers are unpowered.

Common defects

• Dual-extruder loading difficulty

Symptoms: Filament is hard to insert, especially on the right-side tool in the review footage; operators may need a screwdriver, flashlight, or extra hands to fully seat filament.

Likely cause: The filament path is physically awkward and sits far from the drive wheels, making the insertion angle unfavorable and the path less forgiving.
