Alright so it may not make sense. but i think i know why my under extrusion is happening.

Filament is leaking in the hotend and its causing it to leave gaps in the print. so i need your help to figure out how to stop it so i can get back to 3D printing in no time!

It sounds like you may be experiencing a clog in your hotend, which is causing the filament to leak and lead to under extrusion. To address this issue, you can try the following troubleshooting steps:

  1. Heat up the hotend to the printing temperature for the filament you are using.
  2. Use a filament cleaning tool to manually push the filament through the hotend, removing any obstructions or debris.
  3. Perform a cold pull (also known as atomic pull) to clean out any remaining residue or clogs in the hotend.
  4. Check your retraction settings in your slicer software to ensure they are properly calibrated to prevent filament leaking during printing.

By following these steps, you should be able to address the filament leaking issue and reduce under extrusion in your prints.

Inserting The PTFE Tube into PTFE-Lined Hotends with perfect seal!
When swapping nozzles / cleaning your Hotend assembly on a PTFE-Lined Hotend such as one that might come with a Creality Ender 3, TronXY XY-2Pro and others where the PTFE Tube goes all the way down to the nozzle(see ?thegap), you should watch out so you get a perfect seal between the PTFE-Tube and the nozzle.

Step 1: Cut your PTFE-Tube FLAT!, Cut it flat using something like a PTFE-Cutter tool (one can be printed, look it up on your favorite 3d model site) or use a razor knife and very gently and carefully cut down the tube, flat, without squishing it.

Step 2: Heat up your Hotend. Unscrew the nozzle a bit(1mm of unscrewing is enough already!) Side-Tip: while doing this, make sure your Nozzle is never! directly in contact with the heatblock even when screwed all the way in, there should always be a small gap between nozzle and Heatblock.

Step 3: Insert PTFE-Tube all the way in, push it in from the top, attach the bowden coupling clip (usually a small, blue clip that clicks around your coupler.

Step 4: Screw nozzle back in.

Done! You have now changed your PTFE-Tube successfully!
