Critical Failure Modes

It is very important never to leave your Palette unattended. There is a very small chance that a critical failure may occur, for which you need to be present in order to safely stop Palette’s operation.

Please be aware of the following critical failure modes:

1. Filament jam past outgoing drive: Occasionally, filament may not properly splice. If this happens, there is a small chance that the filaments will get jammed next to each other, in the Teflon tube right after the outgoing drive module.
   
   If this jam occurs it will cause the buffer to shrink, until there is no more buffer left for the printer to pull filament from. If this happens, your printer may begin to skip. Your printer may tip over. Your Palette may be pulled off of the structure it is resting on, or a number of other failures may occur. Upon identifying a filament jam, please power down your Palette and consult the troubleshooting section of this manual.
   
2. If your filament becomes tangled, it will no longer be pulled into Palette. If this happens, Palette may pull your filament from its holding system. Depending on the setup of your filament holding, Palette may also pull itself off of the surface it is on. Because of this, it is critical to ensure your filament is not tangled before operations.
   
   Upon identifying a filament tangle, please power down your Palette and fix the filament tangle before beginning your next print.
   
3. In very rare circumstances, Palette’s heater may malfunction. Precautions have been taken to identify malfunctions in the heating systems and upon discovery, safely shut the system down. In rare case, a glitch may occur where these safety systems fail. Such a glitch has not occurred during any testing, but that does not mean it is outside the realm of possibility.
   
   Upon identifying a heater malfunction, please power down your Palette and consult the troubleshooting section of this manual.

For all of the reasons above, you must never leave your Palette unattended. You assume full liability for any event that occurs if a Palette is left unattended.
