Arjun Pro 300

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

Calibration

• Establish the printer’s “known-good” mechanical baseline before any slicing experiment.

Action: Power the machine on, home all axes, then inspect X, Y, and Z motion for smooth travel without catching, grinding, or belt chatter. If the machine uses linear guides, wipe the rails lightly, verify carriage preload is even, and confirm there is no visible play when you apply gentle hand pressure to the toolhead.

Common defects

• Defect: Unverified feature mismatch across the 300-series source family.

Symptoms: Users may assume the Arjun Pro 300 has the exact same hotend, bed, motion system, or leveling hardware as a related 300-class printer, but the provided sources only verify those features on neighboring models rather than on the named printer itself.
