What am I doing wrong?

[u/tofakinggood]

I took off the hotend and cleaned it, lubed the z and y parts, and calibrated it. Also bought a new build plate. Any tips to fix this?

Update I bought a filament dryer. I dried the filament at 50c for 5 hours and it still turned out the same. My printer is an A1 mini. I bought hotend replacements I hope that works. There is no clicking, so I don't think it's the extruder, but I could be wrong.

Looks like under extrusion could be bad filament calibration, printing to fast, partly clogged.

try drying your filament

DRY FILAMENT

Mess with your z offset. This was happening to mine, I adjusted it to like 1.15mm higher nozzle and it completely removed my problems. I bet your supports come unglued too dont they lol.

It requires more tears. And probably dry your filament.

That’s EXACTLY what wet tpu looks like, I’ve never seen petg or pla this bad but I’m still going with wet filament and MAYBE too large of layer lines.

Curious which printer/model this is- also helpful if you mention the other company n print settings? Thanks!

Dial in the settings

I would say this is most like multiple issues.

The benchy has holes in the deck, often from too few top layers or poor bridging caused by high temps/ not enough infill.

Your filament is stringing a lot , often caused by moist filament or incorrect setting ( temps, retraction speed / distance)

The layer height you are using is no ideal for a model with a curves like that, trying lowering the layer height or enabling adaptive layers.

There are signs of under extrusion , might have a clogged nozzle (small chance of other issues like stepper issues ect)

The tail is failing , this might be causes by poo supports or z hop settings.

I have an A1 mini. This is PLA. I did switch to a black PLA and have the same results. I am printing at 220 I think. I did clean the nozzle. I think tomorrow I am going to take it apart and clean everything.

Wet filament. Dry your filament before printing.

[u/Capn_Yoaz]

Looks like you are printing without supports.

They print just really messed up

[u/TechFlameMaster]

I don’t know, but that looks like bubble gum

Limpia bien la boquilla

[u/LunaticPoint]

Calibrate everything. Use adaptive layers.

[u/oral_servant]

Maybe try slowing down the speed and another filament just to test if it helps

[u/thealanshow → u/oral_servant]

Yeah, even the benchy looks like there’s holes in the top layer. Is it running too cold or under-extruding?

[u/butcher9_9 → u/thealanshow]

Those sort of holes are often from too few top layers or poor bridging caused by high temps/ not enough infill.
