So I am a little lost here on fixing up this printer and my vocab on specific parts to the tool head are a little rudimentary.

I received an Ender 5 pro for free that has some issues that I am trying to fix, most of them I have fixed from basic wiring connections, power supplying, and other belt issues that I know to fix from my own K1SE that I own.

However, I have been lost for the past 2 days trying to figure out what to swap out and fix on the tool head. I removed most of the mounting pieces since they were melted from being overheated while right next to the hot end, and I'd prefer that they be metal housing surrounding. I have found the Ylrr Hot End on Ebay but I'm worried about ensuring mounting of the other fans from other 3d printed cooling parts that I can print with the K1SE.

I have looked and found some mounting for extra cooling fans that are 3d printed, but most of them are mounted already onto other metal housings that either already came with the printer or are to Micro Swiss parts. Of parts for cooling the tool head, I have on hand another of the box style fans that I believe is a axial fan, and 2 more of the circular fans, which I believe to be radial fans.

For the actual hot end, I have a replacement one that is newer, but clogged from their assorted parts that I was given, but I do not have any silicone cover that appears to be on similar hot ends.

The base plate/tool head mount is what I'd like to keep on and not order a new one as my budget is pretty small, especially since most of them I see come with the extruder (the motor section that moves the filament?) while I have found that mounted below on the side with aftermarket metal parts that I noticed. Most of the tool head portions for these assemblies that I've looked at both buying or printing have different mounting than what this base plate/tool head mount has.

This is my current extent on troubleshooting this portion of the printer, I am looking for direction on where to look further for fixing and identifying things, and maybe some help in what parts to order.

I really only plan on putting PLA and TPU for prints at about 210-230 *C.

When im printing a banchy i get to a point at around 50% of the print and my extrudor starts doing this and them my print turns out like this(check comment)

Can anyone help i v been strugling with this for about 4/5 days XD

I stripped out the printer hardware and kept only the basics. X, Y, Z power and endstops, lcd and board fan were the only original connections kept. The board was switched to bigtreetech skr mini v3 running marlin. Lazer module is a Aenbulsm air assisted lazer module. Lazer module power is hardwired to PSU. Control wire is can connect to bl touch port or pixel port. Super simple and easy to create firmware for.

When I leave the spool on the machine after a print and I come back later my filament is always broken, it usually snaps in a similar location or in two like this. This sometimes happens after only leaving it for less than a day, in a few hours it just breaks without the machine (ender 5) even running. This filament is sunlu but it happens with other ones too. Any ideas?

Seems the only way I can get my Ender 5 pro to bypass this error is to cover the fan with the piece of paper as shown in the photo so it can get to temps when trying to print petg. No issues at all running pla with the slightly lower temps. It seems to be more so of an issue at the hot end rather then the bed.
So far I’ve pulled off the thermistor, cleaned up the little mess and added a little thermal compound. I’ve done pid tuning which had me change the numbers slightly but no change at all. Any advice would be greatly appreciated
