Exchange filament in Fusion3 F410 mid-print

If your print job runs out of filament mid-print the printer will pause and wait for your input. You will see the message "ERR: Filament Feed" on the LCD.

Begin by lifting up the front cover of the extruder housing to reveal the white tube in the rear of the extruder. This is where filament enters and exits the printer.

Hit the red X in top left of the LCD message window to exit that error message. Then press Tweak.

Press "Swap Filament." This will begin an automated process where the printer will first heat up to temperature.

Once up to the proper temperature the printer will back the remaining several feet of filament out of the printer's Bowden (white plastic) tube. It will dangle outside of the extruder. Once the motor stops you can grab this filament and discard it.

STOP: If filament DID NOT come out of the extruder DO NOT continue. In this case filament is stuck in the Bowden tube and you will need a Maker-E Assistant to help you. Proceeding with the rest of this guide without assistance will cause damage to the printer and result in revocation of your printing certification.

Do not yet press OK on the LCD window that says "Insert New Filament & Press OK." You must wait to complete the next steps before pressing OK.

Locate a roll of filament you would like to use to continue your print. Filament is located in the blue cabinets below the Fusion3 printers.

Be sure to choose the correct filament type! Failure to chose filament type properly can cause prints to fail, damage to the printer, and revocation of your printing certification!

Place filament roll on the white plastic rod inside of the Fusoin3 filament bay. Be sure that the end of the filament will unspool when pointing up. See the second image here for reference. You can recycle empty cardboard filament rolls. Empty plastic filament rolls can go in the trash.

Insert the end of the new filament roll through the copper rivet at the front of the extruder, guide the filament into the white tube at the rear of the extruder, and push filament through until it stops.

Close the lid of the exrtuder housing. Now rotate the orange knob on the right side of the extruder in a clockwise direction.

Rotate the knob until about 1 inch of filament appears inside of the white plastic tube at the rear of the extruder. The tube is semi-opaque so it is a little difficult to see the filament.

Make sure that you follow this step, or else there is a chance that the filament won't catch and you will be unable to start your print. If you bring more than about 1 inch of filament into the white Bowden tube you may damage the printer!

With the filament properly loaded in the extruder (1 inch visible in the white Bowden tube) you may now press OK on the LCD window below the message, "Insert New Filament & Press OK."

The hot end will heat up to temperature. Once the set point is reached the filament will rapidly feed into the length of the Bowden tube. Once it nears the hotend it will slow and gradually extrude from the nozzle.

Let the extrusion complete. When extrusion is completely finished, carefully reach in and grab the pile of filament that was extruded at the rear of the print surface.

Be careful not to touch the hotend of the printer! It is extremely hot and can burn your hand!

The LCD will display "Swap Filament Complete!" Press the red X in the top left of the window. Then press the Back button

Finally, hit the Resume button on the "Printing" window of the LCD.

The hotend will now heat back up to print temperature. Once it is at the set temperature the bed will rise slightly and your print will resume where it paused.
