Arjun 300 Mirror

The Arjun 300 Mirror is an FDM 3D printer from Sri Vignan Technologies with a 300 x 300 x 300 mm build volume.

Calibration

• Verify the machine envelope, thermal readiness, and mechanical baseline before the first extrusion
• Action: Confirm that the printer is installed on a stable, level surface with enough clearance for the full 300 × 300 × 300 mm workspace, the door or access panels, cable movement, and maintenance access around the powder-coated sheet metal chassis. Power the machine on and inspect whether the display, bed heater, axis motors, and extrusion path initialize cleanly.

Common defects

• Missing verified auto-leveling specification
• Symptom: First layers vary across the bed, especially on large parts that span the full 300 × 300 mm footprint.
• Cause: The printer listing does not explicitly confirm automatic bed leveling, so the user may be relying on manual tramming or an undocumented leveling system.
• Solution: Manually verify bed flatness, tram the gantry, and run a first-layer test across multiple points before production prints.
