Hello, Im new in the forum. My name is Sebastián Figueroa, from SCL.

I currently have some “serious” issues with the Creality Ender 2, using the Cura slicer software. The results are shown.

Any recomendations will be appreciated:

Hi,
I have no experience with the Ender but by the looks of it you need to change your retraction settings as the values would appear to be too low.

Hello!

Are you sure that it is because of slicer? I use another slicer and not experienced in Cura, but a bit similar result I had when tried to print with a wet plastic.

For example, if the spool of PLA or P-Carbon are opened and not used in short time, the printing result could be awful. So the filament need to be dryed.

It is just a guess…

It appears that the troubles in your 3D printed object are due to extrusion multiplier or slow setting of the slicing software.
To prevent this, check that you have selected the correct extrusion multiplier. Also, you can decrease the flow settings of the printer’s software to get good results.

What material, temps and print speeds?

My first thought is it is too hot and maybe a little over extrusion. Maybe a little adjust on retraction but retraction is really a fine tuning.

The material is PLA, the Temp is 205°C and the speed is 80mm/s

Thanks so much for you all responses, I think I have the solution, as you said, its the speed now in 70mm/s. The problem was that I printted multiple objects at once, without making adjustments. This video shows how to adjust Cura for Multiple 3D objects at once: 3D Printing Multiple Objects At Once - YouTube

Thanks again to you all.

Sebastian
