Reddit reviews HICTOP Cartridge Heater 24V 40W for Creality Ender 3 3 Pro Ender 5 CR-10S Pro 3D Printer Prusa Mendel （Pack of 3）

I had the same issue.

It's actually really easy to take apart and get to the extruder if you want to check everything.

Unscrew the fans and let them dangle to the side, then you unscrew the parts that are holding the extruder in there. After that you should be able to wiggle the whole thing out.

But honestly, just by looking at your picture, it doesn't look like you have heat creep, or plastic issues. So I doubt it's going to be an issue with the heat break, block, or anything like that. So probably just the heater cartridge.

I was just in your shoes, and successfully spliced a new heater cartridge onto my old wires.

Basically snip off the old wire about 6-8 inches down, strip the wire coating, and splice on a new heater cartridge.

This is the bundle of heater cartridges I got from Amazon. They work perfectly with my MK3. The cartridge itself is slightly longer than the base, but still works without issues.

Also to make splicing easier and faster I got these and they have been working really great.

Okay,

Would this cartridge be okay for my prusa mk2s?

Thanks for the help, I got worried that I would have to disassemble the whole extruder part or have to do some sketchy welding^^
