If you encounter low accuracy or leveling issues with the Kobra 2 printer during printing, it may be due to loose parts caused by transportation. This document will guide you through the process of re-calibrating the leveling.
When adjusting the hex eccentric spacers, make small adjustments.
Power on the printer and raise the Z-axis to the middle height. Use your hand to check if there is any slipping on the inner side of the Z-axis V-shaped pulleys. If there is slipping, use an open-end wrench to adjust the hex eccentric spacers on the inner side of the pulleys until the inner pulleys no longer slip.
Using your hand, shake the print head module from left to right to check for any looseness or excessive tightness. If there is any, use an open-end wrench to adjust the hex eccentric spacers on the lower pulley until the print head module moves smoothly without obvious looseness.
Using your hand, shake the heated bed from left to right to check for any looseness or excessive tightness. If there is any, use an open-end wrench to adjust the two hex eccentric spacers on the lower right pulley until the heated bed moves smoothly without obvious looseness.
Rotate the X/Y axis tensioner knobs clockwise to tighten them fully, and then rotate them counterclockwise one full turn.
On the main interface, click "Prepare" ➜ "Leveling" ➜ "Module calibration" ➜ "Position calibration." The machine will automatically probe and stop near the calibration module. Use the interface's distance units and X/Y axis movement directions to adjust the nozzle to the center position of the calibration module. Once done, click "Save Settings" and then perform the automatic leveling process again.
