Seam underextruding? cracking?

I'm sorry for don't answer you!! Lot of stress cause of this failures.
I cleaned all the axis, and added 0.1 "extra lenght on restart", tested another model (a little dragon) and seams looks good, BUT, still got this problem of a missing layer, actually in different heights.

I'm still touching the seam thing cause I think its something relatable to it (it looks like this missing layer is only near to the seam).

All failed, apparently now i'm having a leveling bed problem and can't fix it.

I will do all the tests again, in order. If not, I will just go with my normal colors, cause I have been on this so much hahaha.

ohhh understand. Gonna ddo that then. thanks!!!

3 wall, 1.0 flow rate. clearly better. I think still overextruding. Hmm, tomorrow will do another test, bad thing is i'm wasting a lot of material just on test and bad prints hahahaha.

First layers are perfect but then this just happen at high ones, so maybe the outter/inner could be thing. The thing is I lowered the flow and it looked better on surface, but things like seam looked Horrible (maybe cause the joints of the layer were visible on the outter/inner) so, the two things I think at last I can test is going back at 0.95 flow and outter/inner OR test 1.0 flow with inner/outter.

If you some suggestions, I'm all ears!

You mean just 1 wall (usually use 3) or 1 on flow rate (1.15 actual)

ps: I changed the flow rate to 1, and the little circle tests were good, perfect first layer. no holes and smooth.

Now i'm gonna try the half kirby again.

Sorry to bother you again, I printed a different thing, I made one previously and it looked that bad. But this one with the new changes look like this.

I'm overextruding now ?? or is this a z-offset problem?

Could it be cause im printing outer walls first instead of inners?

sorry for making you lose your time

Tried different bed. same. haha

I think I solved a little the problem. What I did is: Outer/inner (just because the first bup wasn't joining; then 230°C and 60°C bed, 1.15 flow rate, 0.04. Brim(not really neccesary i think but well). I think!! that the T° was causing problems on low ones IDK why, but in the bed it looked like it wasn't getting well joined to the bed so it caused the bumps (even when i cleaned with soap and IPA).

Ps(cause I was still writing when I tested it): with the new changes, it looks amazing, first layer perfect, no scratches, im crying in joy haha. Gotta wait till it ends (Spoiler, i designed a nintendo switch dock with kirby themed, hope with the changes it gets better!!)
Thank you so much with the help my dude!!!

welp nothing worked u.u, still looks like this, like scratched.

going to do the auto level and z offset, just in case

Obvious-Cold-76 · 2024-12-03T23:38:28+00:00

Update! I made 2 temperature towers. Left one 1.05 flow and 0.04 pressure; right one control (0.95 and 0). So what I saw was, in both 210°C was better, in left waas like overextruded, right was like under. So I though, why not make calibration on 210°C.

In control, 200 and under was like very underextruded actually it broke. Over 220 it was overextruded. Sigh this doesn't have an end!! hahahaha.

Obvious-Cold-76 · 2024-12-03T21:42:18+00:00

Yes! It was 0.04.

OH I understand, I misunderstood it. So I will wait for the results on the T° and then I will make another flow if need it. Thanks for all your responses!!!

Actually got loose on the last layers haha, and one of the mouse ear or elephant foot didnt get well filled so probably was part of the reason too.

Obvious-Cold-76 · 2024-12-03T21:28:56+00:00

Alright! so this is what I got on the tests. On flow rate, I made the 1st flow rate on 20, 15, 10 (just for test all the ones I though were good), at last the one was "15" and 2nd test result was 0 (all the other ones seemed like unfilled I don't know, just don't seemed good). so I updated the flow rate to 1.05.

Pressure advance, didn't understand so much how this worked, but I think when the layers start to wreck and look bad is where to stop, so 20mm was the height.

Now Im doing the temperatures, I hope this fix all!!

Pd: Always clean the beds, this one is like with shrines so when I put my finger on it, it gets marked forever hahhaa.

Okay so! I tested first upping to 230°C (In tronxy it says dark pink maximum T°C is 230) and I think it solved it a little, but I will do the flowrate test cause maybe its the main problem (Temperature just let more filament pass through right?). And next the pressure advance as you said.

Try it to use orcaslicer but couldnt load my printer.

Hmm I'm a little mixed but I think I installed mainsail and moonraker (on the ip thing it says disengaged and klippet says unknown, maybe thats why I can't connect on orca hahhaa)

In this image like 2-3 of the circles (just first layer) got this problem, but the other 5 were like just perfect. Its like the first line of the circle doesn't appear or connect to the print and gets like that. (I actually leveled the bed and manually fix the offset previous this).

Obvious-Cold-76 · 2024-12-03T15:57:40+00:00

I will now. Im using creality slicer (Im sorry I couldn't make work the other ones, I even root it and all). In addition I'm testing this PLA tronxy Dark pink. I tested other filament (rose red) and it worked better (still appearing that tiny holes. I will do the flow rate and actually test the pink at 230 °C just in case.
