I was printing an enormous space marine of 17cm high, about the edge of what the k8200 can print. The estimated print time was 10:41 hours. This wasnt even close as the real time was about 16 hours. The entire day the printer preformed admirably. A flawless print. But 30 fckn minutes before the end. Something terrible had happened.
The black block of ABS which guides the PLA into the extruder sprocket had come lose and the PLA came lose of the sprocket, resulting in printing air instead of PLA. It is the third time that this happened to me. I used scotch tape to prevent this from happening… but it failed…
Tommorow I will design a new feeder part, which cant possible come lose. This mechanical failure is nothing more than a huge design flaw. And I am mad as hell that this had to happen to me after 15:25 hours of flawless printing.
After I designed and printed this new part. I will sandpaper the top of the object, measure the height and print the remaining part to glue it on, though I can and will fix my space marine, it still sux…
I dont have an E3D extruder, looked into it, not worth the effort IMO. I only need a new filament receiver, I dont have to guide the wire from sprocket to extruder, I just have to be sure the wire gets grabbed by the sprocket.

I print this mod and I’m very happy with it. It goes very well with flex filament too. thingiverse.com/thing:744255
GlloQ made one also for 1.75mm extruder
I also print a full extruder system with this : thingiverse.com/thing:203292, you just have to repair the extruder parts with netfab basic and all will be ok.
Hope this can help u

I mean the little black part which guides the filament into the extruder gear. It is the first part where you filament goes through.[/quote]
I took that part away, it’s not necessary. A good hobbed bolt can do the (guiding) job.
I bought this one: tinyurl.com/ztgea8m
