I am having this first layer issue.
I am not sure if its overextrusion or bed leveling…
But could be something else, what u guys think?
Could be the nozzle is too close to the bed, or over extrusion. I’d check the extrusion first.
I think it might be too close. If you look at the bottom of the picture the width of the line changes quite a bit. Also, it looks like each line is in a “U” shape, which to me would be the nozzle pushing out filament and having that filament kind of “U” around it.
It definitely resembles my experience with being too close to the print surface
What is your print speed? Could also be over-extrusion, or both.
Don’t forget to look at temperature. If you are printing too cool the filament doesn’t fuse to the adjoining lines as well, which could be part of what’s going on here.
And last-ditch, most slicers have a setting for first-layer extrusion that lets you deliberately over-extrude a little bit on the first layer, which is necessary with some filaments. You could play around with that setting to see if it fills in the gaps better.
You should always test to make sure you are not over extruding first, otherwise you will get stuck trying to fix it elsewhere. It is simple enough to check. Then you know you are starting from a good place.
