If you're not printing with a Palette, please skip this step.
1) Identify the small tube that came with your Palette 2 (it will be 50 cm long).
2) Identify the pointed side (shown in photo below) and feed it up into the extruder on the back of the printer.
3) Press it up firmly into the extruder until it locked into the eyelet in the bottom of the black extruder housing. Note that you should avoid removing this tube now that it is installed. Removing and re-installing the tube can damage the tube’s ending. When you need to access the filament in the tube, remove the end of the tube in Palette such that this end of the tube remains attached to the printers filament feeder.

UM S3, S5
Note: To help filament feed smoothly from the Teflon tube into the drive gears on the printer, it is best to straighten out the filament before loading it in. Using your fingers, bend 3-5cm at the end of the filament against the curve of the filament in order to straighten it.
