Yesterday, my TAZ4 just stopped extruding. (This is with ABS, only thing I’ve run in the machine.)
I was printing some parts and somewhere along the way the printer stopped extruding. It thought it was but it wasn’t.
I tried to manually extrude and the gear turned but no filament came out. The temp says the extruder is at 230.
I pulled out the filament and it looks like the hobbled bolt had carved into it. I cut that piece out and tried to route new filament but it won’t cause any filament to come out the bottom.
It looks like I can push the filament to about the bottom of the wooden piece but no further. When I pull it back up again the tip is melted.
So, I tried removing the nozzle as per the instructions in the manual: heat to 160, turn off, pliers on heater, use 13mm wrench to turn. I couldn’t grip the heater so I removed the extruder assy and tried again. The Nozzle broke off the aluminum tube.
While I wait to hear back from their product support group, why didn’t the nozzle just unscrew like it was supposed to? Almost looks like there is melted teflon tape, or something like that, burnt around the threads. And what could have caused it to jam/clog in the first place, in the middle of a print?
I really love this printer but I hope I don’t have to do this every 5 weeks…
