What do you do if a filament is stuck in the tube?

What do you do if a filament is stuck in the tube?

Stick something long and thin down the tube and push the broken filament out. An easy way to do this is by using a piece of fresh (non-brittle) filament. Alternatively, you can use a long metal rod like a thin welding rod, or my favorite, a guitar string.

How do you fix filament jam?

If your nozzle is too close to the bed, you may need to relevel it or adjust the nozzle’s Z offset. Long-term: At the end of each print, while the hot end is still hot, push 20–30 mm of filament into the hot end to clear out the fluid plastic and then retract the filament until it is completely out of the hot end.

How do you keep a filament from sticking to the nozzle?

Filament has a better time sticking to the print bed when there is heat involved….

1. Fix the Nozzle Height.
2. Heat the Filament Properly.
3. Unclog the Nozzle.
4. Add Adhesion to the Surface.
5. Increase Bed Temperature.
6. Don’t Use Cooling for the First Layer.
7. Make Your Flow Rates More Consistent.

How do you get old filament out of 3D printers?

Removal of current filament

1. Step 1: Preheat your hot end based on the temperature guidelines of your current filament.
2. Step 2: Wait until the hot end heats up to the required temperature.
3. Step 3: Manually extrude a small portion of the filament.
4. Step 4: Push down the coupling to release the filament from the hot end.

What causes PETG to jam?

If your extruder temperature is too low during printing, the PETG filament will not flow and will have difficulty extruding. If the filament is softening in the hot end, the extruder will ‘chew out’ the filament, causing a nozzle jam.

Why is filament not coming out of nozzle?

This can happen if foreign debris is trapped inside the nozzle, when hot plastic sits inside the extruder too long, or if the thermal cooling for the extruder is not sufficient and the filament begins to soften outside of the desired melt zone.

How do I know if I have heat creep?

You can see evidence of heat creep when your 3D printed part looks only half-complete with a fuzzy top (like in the above image). You can also detect heat creep when you pull your filament out and there’s an air bubble.
