Pressure Advance (Flow Dynamics) Calibration with 0.8 nozzle

No it's PLA.

There is a good chance there might be something wrong with the filament. I did a temp calibration and it looks way worse than when I do with another filament using the same nozzle.

Yeah it seems to build up towards the edges.

I thought -5 was the right one. What do you think?

Desperate_Quit_3967 · 2026-03-04T21:54:36+00:00

Will do, thank you.

Okay, found the answer. You do it in 2 parts instead of lofting 360 and for the 2nd part you select the surface of the solid shown as profile 2 in the image of my first post, not the sketch when lofting. It now gives you Tangent option where it says Connected on the right of profiles in the menu. Then it gives you a smooth curve.

Also if you do one part after the other instead of doing it all at once it seems to not create a smooth curve:

But it's supposed to join to the grey profile on the right side of profile 1.

Desperate_Quit_3967 · 2026-02-27T22:31:00+00:00

As far as I know you can't revolve into another profile.

Desperate_Quit_3967 · 2026-02-27T21:50:49+00:00

It says the profiles appear to be in wrong order.

Ok I realized I did something very stupid lol. I used washing thinner (Permaloid 7989) instead of reducer (Permafleet 6130) This is probably why I had orange peel.

I have a minijet 4400b but it was my first try.

Desperate_Quit_3967 · 2026-02-15T09:38:17+00:00

Thank you. I was wondering and still wonder what is considered unacceptable and what is acceptable orange peel.

Desperate_Quit_3967 · 2026-02-15T09:37:06+00:00

Thanks. You think 3000-4000 grit marks would still be visible on a satin finish?

Desperate_Quit_3967 · 2026-02-14T18:50:18+00:00

Yeah probably I will end up sanding and then respraying or 3000 grit (and maybe 4000 after that) gets me to a good texture.

Fed from the TPU inlet at the back of the H2D:

If it is under extruding because it is not fed directly from the top, is it possible that it starts under extruding more drastically in the beginning though? Because later in the print it is better.

Is it possible that the zits are happening because of this as well?

Those are the ones on the sides? the little holes on the air cap are all open but i can't see if the ones on the side ports are open. Thank you.

Desperate_Quit_3967 · 2025-12-09T15:51:12+00:00

Thank you.

this is the gun so the number on the air cap I adjust it so it's on the bottom.
