Avoid This PETG Mistake On A Benchy

This big 3d printing mistake happened while I was trying to print the perfect PETG Benchy and it was not obvious why it happened. At first, I printed a successful Benchy but then the next one turned out like the one in the thumbnail (with some minor setting changes). This is every 3d printing beginner's nightmare because the changes I made were small? I went back to the exact same slicer settings and the same disaster happened. Let me take you through my troubleshooting process of how I solved this problem and gained an extra braincell!

Hi, my name is Daniel and I like to make stuff. My journey on Youtube began with creating things around the home with my 3D printer. I'm mainly focused on making functional items because I am relatively cheap and don't like to buy overpriced goods. Also, making my own things means that I can customize the item to my specific need. I hope that my channel inspires you to Just Make It!

That is indeed a beautiful Benchy. Well done!

Daniel, where did you get a dual sided part cooling fan? Is that something you printed? If so, can you post the .STL ?

Hey Daniel, thanks for sharing! Also just read in the comments that you designed that 2 part cooling piece nice!! I remember it was an upgrade people did for the adventurer 3, Also some adventurer 3 users actually managed to install a e3d full metal hot end on their machines but I can't figure out any information regarding the adv4... It's one upgrade I would love to do.

Just to let everybody know, FlashForge suggests you not turn off your printer while the Heat Break Cooling fan is running. Let the fan run till it shuts off automatically at 50C, otherwise filament ABOVE the hot end (the stuff cooled by the Heat Break Fan) will melt from heat in the hot end, creating a clog that's hard to clear. If that happens, heating the nozzle to max temperature will not help clear this, since the clog is above the hot nozzle and continuously cooled by the Heat Break fan.

If you have a clog, what I've done is (and perhaps an alternative to what Daniel showed): 1st unload your filament, then disconnect the Bowden tube from the extruder, preheating the Nozzle to max temperature, then push the Nozzle Cleaning Tool (large PIN) down as far as it will go. It doesn't go all the way out the other end, the diameter of that Cleaning Pin is wider than the nozzle diameter.

If it works you'll see a blob shoot out through the nozzle. Then remove the Cleaning Tool, because its hot now remove it quickly, to prevent the hot PIN from melting/damaging the PTFE tube that's inside the nozzle. Hope that's clear.
