I'm hearing a clicking sounds during retractions.
If you can hear the gears clicking against each other during printing (normally on retraction) this is most likely caused by backlash (the gears being able to move very slightly, independently of one and other). You can check for this by trying to move the large gear by hand, it will probably move freely over a very small angle.
Backlash is caused by poor gear alignment, a highly exaggerated example of this is shown in the picture. The fix is simple, loosen the 3 screws that hold the body to the motor and rotate the extruder such that the gears are fully meshed. You know they are fully meshed when the large gear is no longer able to move freely. Re-tighten the screws on the lid and the problem should be fixed.
If you are unable to get the gears to fully mesh by removing the screws on the lid, it may be necessary to loosen the screw behind the groove-mount and adjust the body position.

- Ensure the PTFE is installed in the Idler.
- Ensure that the steel pinion gear is not too far back towards the motor, allowing the idler to slide back and forth along the motor shaft.
Drive gear hard to turn when lid tightened
Be sure that the steel pinion gear is not above the height of the Acetal gear. If it is, the idler will pinch it when the lid is fitted.
It is possible to over tighten the lid screws on the Titan, over-tightening the lid screws can result in permanently damaging the bearings. In the first instance back off the screw slightly and see if the black gear is able to move more freely. If you notice the bearing is not able to rotate freely then you will need to purchase a replacement. If the bearing appears to be showing signs of rust or has disintegrated you may have a unit that was affected by bearing gate, in this case, contact firstname.lastname@example.org.
HotEnd is wobbly
This is normally because the PTFE guide has not been inserted. Please refer to the relevant section of the documentation and ensure that this part is fitted. If you are still having trouble, please contact support.
