Take apart hotend

[feare56]

My extruder is jammed or clogged and I am in need of taking it apart, I've tried everything without cracking it open. The problem is that I don't know how to take it apart. How would I take it apart?

What printer do you have ? Your seller doesn't give you a procedure ?
Here 's an example, should probably give you a good idea of where to go.

I have a prusa Mendel i2, I got it for trading one of my ps3's so I didn't buy the kit. The hotend looks like a square block with the nozzle attached to it

Any help? I am really hoping to get it to work soon

I don't have your model, but would either of these help?

unfortunately those didn't help. I have found what type of hot end it is, it is a J-Head Mk IV-B Hot End for 3mm filament if that helps. I so far haven't found a video that shows how to take it apart

I don't think you can take the J-Head Mk IV-B apart. The methods that worked for me when I had serious clogging in that specific hotend was the "atomic" method

or to heat the nozzle to max temperature and try to force filament through..

One of my friends suggested that but didn't say to lower to 90, I'll have to try it again like that
