I am really stumped on this one.
I was having extruding issues the filament would extrude right up until the melt zone and then right as I get to the melt zone it just chews into the hobbed bolt
prusa i2 on ramps 1.4 with a mkiv-b jhead printing abs at 200-230c
oddly this happened right after I got a new roll of white abs filament from ebay.
I was able to print about 3 parts with it and everything was going nicely. then that's when the jamming happened.
I have been using same jhead a few months no issues. I pulled it all apart to find a clogged up wore out ptfe liner so I replaced that soaked the j head overnight in abs replaced the resistor with a 40w ceramic heater
im getting exact temp readings as far as I can tell but for some reason I just cant get this to extrude. I even tried pushing the filament through it so im not sure what my issue is bout to drive me crazy cause ive been wanting to do some printing for a week now
