T-rex problems.
Hey all.
I have been trying to print the big t-rex from prusa.
And I am having alot of problems. I have printed one piece so far.
And after this all the problems started.
It prints very well the first hour or so. and then it skips a whole layer prints 5-6layers and then the nozzle jams.
It has done this god knows how many times no. I have in my desk a whole pile of not finished bones.
I have tried to re calibrate the printer.
Tried to get the files one more time from thingivers and do the g-codes again. This actually seemed to make it a little further, but then did the exact same again.
The filament is trying to get in. But the gears just grinds on it, and it seems to not be able to keep up with the flow.
I am a little lost.
Hope someone can come with some inputs or webpages i can look at.
Best regards.

Re: T-rex problems.
I just printed the T-Rex model last week... went fine except for choosing the proper supports was a bit of a pain.
If the print is actually missing a full layer, a plugged nozzle is likely to blame. It also explains the filament grinding. I just went through a mess of this myself. Glow in the Dark, I'll never use it again. Half a roll free for the shipping costs. It took many attempts to clear the nozzle, and pretty sure there was debris inside the teflon in the heat break adding to my woes. Once I had the nozzle working reliably, still had a few hiccups; and they finally went away after blowing the snot out of the heat break with canned air.
The nozzle plugged, the extruder shredded the filament at the gears, dust and fragments went everywhere, including falling inside the heat break and even outside the teflon. Simply clearing the nozzle with cold pulls did nothing for the dust and debris in the cold side of the heat break. Removing the nozzle and using canned air to blow up into the hot end finally cleared the gunk. My theory is a piece of debris wouldn't move down the tube, but instead would wedge the filament somewhere up on the cold side.
