Ultimately, your stepper motor is unsuccessful in driving the filament through the extruder. A couple potential reasons: extruder temperature isn't high enough. This could either be operator error from not setting the temperature correctly or your machine is getting a false reading. Typically, for ABS/PLA, you can get away with a low extruding temperature ...

The photograph and your description indicate that the drive gear is eating the filament because the filament has stopped moving. The least likely problem would be that something is jammed at the spool or between the spool and the entry to the drive mechanism. The more likely problem is that your nozzle is clogged. It is simple to determine if that is the ...

It looks like a problem with feeding filament. It could be good to know if you did try such big printouts before but even if - from your picture it looks like on far end there is too less filament but on near end it's too much of it (because of 110%). And near the big circle it looks better even on far end. And there are "waves" close to big circle. How is ...

Cura is exceptionally bad at printing details comparable in size to the configured line width. Lower your wall line width to something like half the wall thickness (i.e. 0.225 mm) and see if that works. With a standard 0.4 mm nozzle I've had success printing tiny details with 0.2 mm line width or smaller. For example: And here's your model printed at 0.225 ...

The Ultimaker 2+ is a single extruder 3D printer. Without changing the PLA spool and PVA spool continuously during the print you practically cannot make water soluble supports on the Ultimaker 2+ which can be done on the Ultimaker 3. Note that PVA (from experience) is strange material to print, the filament is very hygroscopic and will form bubbles during ...

For the Ultimaker 2 flow is typically handled on the printer. You could make a feature request at github to let Flow be enabled for Ultimaker 2 printers. As for your problem: that sounds more like a dimensional accuracy problem to me. I suggest setting Horizontal Expansion to -0.15mm.

I had the same issue. It can happen for number of reasons. One of them is too low print temperature as stepper cant push the filament through. Also you could have partially blocked nozzle or if you print with PLA and have left it out for a while its diameter can enlarge and get stuck in the bowden tube.

PLA and ABS are hard plastics. They are not water-soluble. If you print with these materials, just snap printed support materials off and clean the interface layer with a knife and sanding. To remove the support, it is best to use strong tweezers or a pair of pliers to grip and then apply some force. Generally, I use needle pliers, but occasionally I also ...

It looks like your nozzle is jammed, since the filament is being chewed. You can fix this by heating the extruder up to around 220 C ( or just about 15 degrees above the recommended printing temp for your filament), then attempting to push some filament through the extruder. If this doesn't work, use a small wire and push it through the nozzle a few times, ...

I had a clogged filament. I heated up to 240 C, and pushed a wire up through the nozzle. It took some effort, and much patience is expected. I left the wire inside, as it helped soften the PLA. Then I pushed the filament by hand from top. After some efforts, the needle moved, indicating the movement of the PLA clog. Once the PLA starts pushing the clogged ...

So, problem was too low printing temperature. It was 200c. For PLA I have it was too low. Now I'm confused, for PLA the temperature range for printing is given from 180-210 (It is even written on particular coil). Does it mean that even printing in this range I should adjust temperature for each of plastics I have? Update: I have researched a bit about ...
