Experiment with upping the Material flow rate in your slicer (in your case Cura). Try something like 300%. Stand watch and see what happens. </p>

I just print a baymax that came with the SD from the printer. and it print great. I think the problem is with the configuration from Cura

this is more than a year and half later: but always check the line *above* flow to be the right diameter! I had one time CURA resetting from 1.75 to 2.85mm after an update.

<p>That looks like horrible underextrusion. Either the extruder steps/mm are way off, but more likely is that your nozzle is clogged (because I wouldn't expect the steps/mm to be this far off). It's also possible that the temperature you're printing at is inappropriate for the filament you're using. Also, make sure that the fan that is cooling the heatsink of the extruder is always on. If not, filament may soften in places it's not supposed to and jam.</p>

<p>Try heating the extruder up and pushing the filament through by hand. You'll probably feel a lot of resistance and the filament won't come out smoothly. You could try doing a couple of <a href="http://bukobot.com/nozzle-cleaning" rel="noreferrer">cold pulls</a>, that is, put a piece of filament in while the hotend is hot, then let it cool down and attempt to extract the filament at the lowest possible temperature. This may pull debris or particles blocking the nozzle out.</p>

<p>If this doesn't help, there are various other ways of clearing a clog from the nozzle. One popular technique is disassembling the entire hotend and burning out all the debris from the nozzle with a blowtorch. Another is using a special drill bit to clear out the nozzle but this has a high risk of damaging it.</p>

I use a strand from a wire to clear the nozzle if I need it. But the cold pull is preferred.

Hi, I printed a baymax that came with the SD card from the printer (I update the post), and it printed really well. I think the problem is the cura configuration. Is there any how to get the configuration from the baymax file?

Could you edit the title of your question to be slightly more descriptive of the problem? "Problems" is too generic.

You should include a bit more information in your question, like what settings you are printing at, what material, etc...

Don't use the GCode on the memory card. Setup your Cura correctly and try with new filament.
