@BoozeKashi - I have a few tricks up my sleeve, one is a 1.75mm rod (same size as the filament.)
So basically, you need to replace the PTFE inside the hot end, you should find hundreds of photos of that online. I just remove the bottom plate (3 screws on the bottom of the print head), the plate comes off, vice grips for getting the nozzle out, then use my little 1.75mm rod to push the PTFE out from the top where the filament line screws into (yes you need to unscrew this.)
Once out, replace with 3mm OD 2mm ID PTFE line, make sure the line is very round before inserting, then just cut to size and install a new nozzle (0.4mm) - I keep those on hand now.
@proclaim - I’m very happy to hear that. I will say, my 3 printers, dispite their issues, still remain my favorite, in fact, I’m about to sell my Flashforge farm and buy a couple more. Now that I know all the little kinks, it’s been really nice to use them. I do wish the software was more reliable with it’s network communications, I wish it was a raspberry pi 2 inside, then a usb network dongle might solve some issues, - it’s still amazing through what you guys did with the ESP8266.
