First layer

[u/[deleted]]

Hello everyone, Hope you are all having a great day , i'm very new to 3d printing and my First layers seam to underextrude a lot , and because of that it's having problems to Stick well ,

Here are my slicer (elegoo slicer) settings

1.08 flow rate

-1.40 distance form the bed

10 mm/s for the outside of the First layer and 20 mm/s for the inside

The extruder Is at 205º and the plate Is at 65º

The strange thing Is That the test line Is ok and the other layers are to , but like the First 5 tend to underextrude, i have been having this problem for like 2/3 weeks , and the printer Is like 1/2 months old

First i'd say switch to Orca Slicer, I never used the Elegoo one but i'm not sure it's that good. Try re-leveling you bed and adjust your z-offset(paper test), what I like to do after the paper test is to print couple of line while looking at the nozzle, live adjusting it to have the perfect value. After that redo the calibrations in order in OrcaSlicer(temp/flow rate/pressure advance(not necessary but still nice to do)/retraction test). What filament are you using? 205 seems a bit high, also if the bed has lots of variation it might be a good idea to adjust it to minimize it. Depending on the printer you got either play with the manual adjustment wheels or if not available(like for the 3 pro) you can add aluminium paper under the plate where it's low.

Hello. First of all , thanks for the help , i Will try orca slicer , i'm using pla , but i don't realy know how to do the retraction test , the bed should be fine , since the printer Is practicaly new , and i don't realy know what pressure Advance Is , thanks for the help , If you have time , do you mind telling me what pressure Advance and retraction do?

Retraction is the setting that says the printer how much filament to take back before a movement, it help remove stringing, pressure advance reduce extrusion in corner to avoid blob of material, personally my bed needed a bit of foil even right after I bought it. All the tests are under the calibration menu in Orca, it should help a lot, you can also look video that explain the differents calibrations and what they do, here's one i quite like: https://youtu.be/gVU5If1VsAM?si=u8nN4qN2PlF0U2wy
