Calibration

• Verify the machine state before any calibration print
• Action: Power on the printer, let the hotend and bed remain cold for a minute, and inspect the motion system by hand for smooth travel on X, Y, and both Z screws. Confirm the belts are properly tensioned, the carriage is not rubbing, the build plate is seated correctly, and the spool path is unobstructed.
