FAILED! Fix the New Hictop, Tenlong Titan Extruder Upgrade before it happens to you too! D3 Pro Hero

After several successful prints using the new Hictop Titan upgraded extruders on my D3 Pro IDEX printer, I had a major fail where the whole heater block & nozzle assembly dropped down. It got pushed out by the filament and was rubbing against the build plate when I checked the printer mid-print. It was no longer extruding because the build plate was blocking the filament from exiting the nozzle. This is how I fixed it. The main issue is that the screws that hold the heater block throat in the heat sink are not tight enough. The heat/cool cycles may have loosened them up more, and they became loose enough that the throat slipped out of the heat sink. Check to make sure that yours are tight before printing! The Hictop D3 Titan extruder is available on Amazon: https://amzn.to/3gzPZoN The Hictop (Tenlog) D3 Pro Printer is also available here: https://amzn.to/2WAfSNW I have been very impressed by the value and performance of this printer at this price point, although I would only recommend it to experienced 3D printing users. Filaments I Use: I've been using the Taulman 910 Nylon Alloy filament. It retains the best properties of nylon (it's strength, chemical resistance, heat deflection, etc) while adding rigidity. It is much more rigid than plain nylon. I also like their black color. I buy mine from Amazon: (1KG Black - https://amzn.to/3eESRQ4 ) (1lb Black - https://amzn.to/3hgkbps ) It's also available in a natural nylon color, https://amzn.to/30uBKLF but this doesn't look as good as the black. NinjaFlex 1.75mm for the stock extruder, but I prefer printing NinjaFlex and other flexible TPU materials in 3mm, and I explain why in this video, and how to convert:    • Best Ninjaflex TPU Printing With This Simp...   NinjaFlex 1.75mm [Black 1kg - https://amzn.to/2RBjgVQ] [White 1kg - https://amzn.to/32H4h37] NinjaFlex 3.00mm [Black 1kg - https://amzn.to/33C0ZNH] [White 1kg - https://amzn.to/3iJfNQQ] Aquatek X1 Water-Soluble Support by 3DXtech - https://www.3dxtech.com/aquatek-x1-ad... This is a game-changer in terms of printing materials like NinjaFlex where you can't use the same material for support because it sticks too well to itself and is impossible to remove.
