So I've been playing with the Ultimaker 2 Extended for a few weeks now and I feel like I've got a pretty good handle on how it works...or at least where to troubleshoot when it doesn't work. I've messed with the feeder tension, cleaned the bowden tube, done the Atomic Pull, etc. But I'm not sure what to do about this...
I was printing a file and at hour 4+ I noticed that it was not longer extruding (PLA). It wasn't making those horrible clicking sounds from the feeder, just zooming around and not printing. I cancelled the print and tried heating up the nozzle and moving the material through...nothing but the dreaded clicking noise from the feeder. Upon trying to 'change' the material, the feeder would not grab the material and back it out of the nozzle and bowden tube. So now it is stuck. It wont go forward and it wont go back. Any thoughts on how to deal with this little conundrum? Cut the filament below the feeder and try releasing the bowden tube and pulling it out that way?
Also, feeder problems are like the plague with this machine....any thoughts on minimizing these issues?
Thanks so much for your help and time!
