Welcome to the SeeMeCNC Community

Everything was working so well recently, but I switched to a new pritt stick like glue yesterday that I thought was the one every else used (goes invisible after drying) and seemingly the Taulman Bridge didnt stick (or came undone during the 5hr print). Woke up to the rank smell of burnt nylon fumes (Printer is in my garage which next to the house).

Not only did it come unstuck, the nylon somehow forced itself up backwards all through every nook and cranny (even into the fans) of the head. Given the melting point of the nylon is no doubt higher than the melting point of the black plastic (ABS?) Rostock use (or the wiring..) Im thinking this is not recoverable at all?

It's probably a good time to upgrade to Trick Laser Arms and get yourself a E3D v6 or Prometheus hotend. If you're going to be printing specialty filaments, you want a hotend that can handle the temps necessary. I'm surprised you are printing nylon with the stock hotend. Maybe I'm misinformed but I thought you needed a pretty high temp to print nylon successfuly?

Yeah I was planning an E3D anyhow.. though the stock hot end is ok till 250c and you can print Bridge from 235 (241 ideally) no problem. You cant even specify over 247c on the stock firmware and the stock PSU cant get over 230c with a 70c bed....

I havent had any issues and have been printing mostly nylon to date (only have Nylon and PLA).

I've only printed ABS, PLA, and PETG. I don't dare go above 235 on the stock hotend in case it should overshoot by a lot for some reason. I have a Corsair PSU so it can get it as hot as I need providing the firmware will let it. I have a Prometheus V2 hiding in the wings so I will upgrade at some point but hopefully not for the same reason that you now need to.

I call it the snowball fail.

I think mine stopped extruding for a bit and then resumed when it was too high to stick to anything. This happened before I lowered my retract speed and distance, so I caused my own temporary clog.

Wow... All the fail balls here are amazing!

Nylon is a bad one to have fail like that. Upgrade hot-end time....

that looks like the blob kodachrome
thankfully i didnt have a major fail like those

How/why did the cooling fans become unattached?
