Strange texture

Hello!


I Finally managed to finish my 3d printer, after calibrating the bed, these are some of my first printings in PLA:

they show a strange pattern with the infill and i dont know of to solve it, I tried using different parameters, but nothings seems to improve the quality

Can you give any hints to solve this problem?

Thank you


PLA 200ºC 60% infill.


PLA 200ºC 100% infill.

Does it seem to extrude OK in open air? Raise the hotend up of the bed as far as you can and see if you get a nice smooth line extruding out of it.

This kind of looks like too low extrusion but also looks a bit blobby. Maybe it's not extruding properly due to low quality filament or wrong temperature.

It looks like you are not extruding enough.
Have you calibrated your lenght of extrusion of the filament?
Have you set the right diameter in your slicer for the filament?

Extruder
At first i thougt this was the so called retraction.... until I set to print a large square, then the extruder did that while doing a straigt line. I'll try a slower printing speed so I dont get overpressure on the extruder and/or raise temp to 210-220 so it can extrude faster...but tomorrow hah it's late for today

thanks for your help
