I had a print fail a while back and the filament covered the hot end. I attempted to replace the nozzle to fix the no filament issue but it looks like the unit has a cheap Chinese heater block that I have seen mentioned or It's a really old model which is nothing like the current ones with heat sinks. I am hoping to find a replacement heater that will work in place of this hot end. I suspect from looking at the design and the things I have read that I will likely need a different heater block. It might just connect the heat tube with the nozzle if both are bottomed out which was mentioned as not a good thing. The heat tube/break seems to be the reason I can't properly get the filament out as it is letting it melt too far up since it has the nut against the heater block and no radiator.
This has a picture of the print head mount. I suspect I have to change that out in order to handle the new styles of print heads.
Any suggestions are appreciated.
It should be a heat break but does not look like it was implemented that way the first picture shows the unit. It screws into/through the bottom of the carrier has a fan on it but no proper heatsink.
