Wow. Thanks for this idea. I'll try something like it.

Hi, I've noticed that on my Ultimaker 2 Extended when the extruder prints the blob before a job it is almost one inch above the build plate. Versus the blob being 7-8 mm above the build plate on the Ultimaker 3s. Is this something that can be adjusted? The long distance makes it difficult for the extruder to scrape off the blob along the plate before it starts printing. It can get caught up in the first layer/raft. See attached pics.

Thanks for your reply. Of course, as soon as I messaged about this, the problem has not reoccured. I have been cutting filament at angles and this is a fairly fresh reel. I just notice the filament has a natural bend coming off the reel and the bend stays through and out the tube so when the filament backs off after a job it can get stuck on the edge of the coupler. Sometimes I can steer in manually with a spatula or driver but this shouldn't be the norm. Again, the problem seems to have abated for now. I'll keep an eye on it. Thanks for the quick reply.

Update please? Has this post been approved by moderator?

I've noticed that at the end of a printing job on my Ultimaker 2 Extended the feeder is retracting the filament back too far. So the filament comes out of the top of the extruder. Because of the natural bend in the filament it's getting stuck on the top edge and the feeder gets hung up trying to push the filament back in when a new job starts. So I have to manually aim the filament back into the extruder before every job. This is a relatively new extruder (only a few printing hours, but the extruder nozzle is about a year old) Is there a way to adjust the end gcode in Cura so the filament doesn't back out of the extruder too far? I'm a gcode noob.
