### ⭐ Nowhere close to "original". Ruined my $35 cool plate...
*by K***D on July 9, 2025*

I removed the old hotend per the instructions on Anycubic's website. The install for this was easy and it seemed to match the dimensions and look of the original with no visible differences, at first. Once I installed it, I did a PID calibration on the printer as recommended by the manufacturer and fired up my first test print of a temp tower. After the first initial layer, the nozzle immediately began to glob out filament and make a huge mess of the next couple of layers until I manually stopped the print. I took it apart and removed the hotend and cleaned a ton of filament that was jammed in the nozzle. I reinstalled the hotend but what I didn't notice at the time is that the PTFE guide tube that had pushed itself out of the neck about 2mm. When I went to reinstall it, I did just as the first time and pushed up until it was flush and locked the lever back in position. It seemed to have tension when pulling down so I put things back together and fired up a second print. Same thing, temp tower. This time, it laid down the first layer nearly perfectly so I walked out the room. As I was walking away, I heard a loud grinding noise so I ran back in to see what was going on. The gap in the PTFE tube caused the neck to not sit flush and it was not fully locked in position so it had dropped down after the first layer and been dragged along my $35 build plate and dug huge holes and trails in it. I stopped the print, heated up the print head and removed it again and as I pulled it out of the print head, this time the PTFE guide tube fell completely out of the hotend and onto the floor along with a small piece of filament that was left inside. Now not only am I out a functional hotend but I lost a $35 build plate. I try not to leave bad reviews unless I have to and the second install was a bit of user error as I should have noticed, at the point, that the PTFE guide tube was not properly glued into the unit like the factory ones are but it certainly shouldn't fall out.
