Struggling with quality

Thanks. Linear advance? Is that the same as pressure advance? I use Bambu studio.

Yea the flow going up shocked me a bit, especially that high, I did read some people saying the bambu profile is a bit on the lean side for flow but!

I think first time round the scars were due to adhesion, a gentle lift meaning the filament got ploughed through by the nozzle and left the scars on each corner.

Second time round I read that it could have been pillowing? Where the speed helped heat get trapped inside the gyroid the layer is laid on top and causes a gentle lift of top surface and again appears to be over extrusion or rough patches. The slower speed and the more top layers helped to control this.

To be honest you could go down such a rabbit hole with this, I like perfection, but in all honesty this needs to be functional, and it is! So I could leave it, but I want it to look good!

Yeah. Brain fart and couldn’t remember what it was called. I knew that was close and ran with it lol.

That will do it for sure. Get you a Kdevi plate. Solved those issues for me for sure.

I understand this completely. As long as the parts fit together correctly and the chair rolls…its good!

I somehow resemble that remark…:rofl: My OCD - has me running down rabbit holes all the time. I had to do a few things around the house or I’d end up in a shed with my printers. lol

What PETG are you using here?

I had to dial in the flow for the Creality Hyper because it quite a bit different than the Bambu or Sunlu.

This is probably around 4-5 hours of me tinkering with this with input from @NWCC

Man I feel like such a newb surrounded by the people here.

In my town I am like the 3D guru :rofl: since the word got out that I make these… everyone asks ME questions…:joy:

And that is how its supposed to work. You learn from those that came before you, and you teach the ones that come after you!

This is actually Bambu PETG. So I kind of assumed there profile would be good, as its been fine for pla for me.

However a bit of AI input reveals there’s a fair few discussions stating that the profile is a fair bit out alot of the time

Was this tpu testing?

That’s next on my list :sob:

PETG Basic or HF?

I’ve only run their HF so far and it prints beautifully with stock settings.

I spent the afternoon calibrating two machines for both PETG and PLA. Talk about a lot of tests. One of the machines is a Prusa. Orca sure makes it easier to calibrate. Everything is right there including a good tutorial.
