I recently finished building a MendelMax 1.5 3D printer and I got it working really well, then the hotend melted.
I got a new Magma hotend to replace the old J-Head IV that worked, so far the Magma hotend has been unable to print because the extruder keeps trying to push plastic through but the hotend seems to be full, jamming it up and making the hobbed bolt carve into the filament. I have been stuck on this for weeks without and breakthroughs and I'm completely out of ideas.
I have also tried using a Budaschnozzle unfortunately, that had the same issue as the Magma hotend and jammed up.
I'm using 1.75mm ABS plastic and my extruder is a

I'm getting really annoyed by this issue and would love to have it fixed and printing again.
Thanks!
P.S I'm going to post this on the RepRap forums and RepRap subbreddit to get the most help, thanks!
