Calibration

  • Start with a full mechanical squareness check before any slicer tuning.

Action: Power off the printer, loosen nothing unless necessary, and inspect the frame for any obvious shipping shift, especially around the Z towers, X gantry, bed carriage, and the dual-Z synchronization belt. Verify that both Z lead screws rotate freely and that the X gantry sits level across the full width of the printer.

Common defects

1. Ambiguous firmware and feature set across Rock 3 / Rock 3 Pro variants

Symptoms: Users may see conflicting claims about bed type, power supply rating, or feature availability depending on vendor listing or video source. The materials supplied here are not fully consistent on PSU wattage, and some descriptions blend Rock 3 and Rock 3 Pro terminology.
