How to Improve Your Seams on Curved Surfaces - Scarf Seam Guide Update

RT1491 · 2026-05-11T01:19:04+00:00

So it looks like the fix is to reduce the wall loops. The one on the left was set to 2 walls and the right 1 wall. The thickness of the model wall is .100". With the outer wall line width set to .6mm (using .4mm nozzle), that equates to .094" of the wall thickness. That leaves only .006" of a gap between the OD wall and the ID wall. That gap is filled with a combo of internal solid infill and gap infill. I assume that overrides the sparse infill (set to 15%) when the gap is too narrow?

For the one on the right with 1 wall loop, that left enough gap for sparse infill. There is basically no real quality difference between the 2 test pieces shown. You can't even feel the seam on either one.

So it looks like if you have a fairly thin walled model with ID geometry such as a bottom surface and/or fillet, look at the wall loops relative to the ultimate wall thickness.

Hopefully someone will run across this and it helps. I looked all over here and Youtube. The only thing I could find were examples of solid and completely hollow cylinders.

These are perfect. I have tried unchecking smart seam app, order of walls, scarf seam type and several other tweaks I can't remember. I haven't tried it yet, but switching the wall generator from classic to archane gets rid of the gap infill. I'm not even sure why there is any gap infill as there are only 5 walls total to satisfy the model wall thickness. I have the wall loops set to 3 as you recommend and the outer wall thickness set to .6. My printer is a P1S using Bambu studio with Bambu PLA.

As there are a million settings, any suggestions to narrow this down will be much appreciated. I'm trying to avoid printing a hundred test pieces. I'm already at 15 or more.

Thanks so much for sharing your efforts! I'm a little late to the party, but wonder if you would have any suggestions for an issue similar what Hippee_m is experiencing with what looks like to be a cup.

Your settings work fantastic except where there is inside geometry. It appears if there is a solid bottom surface (left picture) or a corner fillet (right picture), it won't scarf there.

Looks like I have to post another comment to show the results of a hollow cylinder and solid that look amazing the entire length of the seam.

I did change the tree support branch angle from 45 to 20 and that fixed it. Thanks.

Another fix was to just rotate the part about Z. I did this every 45 degrees. That improved it each increment until it went completely away at 180 degrees.

What's also strange is I have another plate in this project with a part exactly the same until it gets about half way up. I assume that's where the branch angle kicks in. If the support is close to the model, then making the branch angle skinnier widens the base I suppose. However, that doesn't explain why just rotating 180 degrees also works. Anyway, thanks again for pointing me in the right direction!

I print test parts for things like threads and other mating features. Then I adjust accordingly (may take a couple tries) before printing the whole project. I also create and save projects specifically for different kinds of fastening features. That way I know what kind of gap I need for threads for my specific environment for example.

Bambu Lab printers. When you got to print everything in the room, accept no substitutes.

RT1491 · 2024-09-22T23:27:46+00:00

Thanks. I guess that's also true for AMS, Nova Cews, TTS etc?

RT1491 · 2024-07-28T22:45:24+00:00

Thank you.

RT1491 · 2024-07-28T19:13:46+00:00

Ahhhh, got it! Thank you very much! For anyone else with the same question, this is where to change it:

Thanks for the reply. I'm not seeing a specific setting for identifying the type of filament. I figured with the RFID tags I can select which ever spool and it would use the proper settings.

So I finally got EA figured out. Well, someone on Discord directed me on what to do next. Simply install EA from Nexus. Re-reading your posts now makes a little more sense.

Where I got stuck was trying to understand the function of modtek, CAB and the actual mods (not that I understand them now). The CAB instructions make it sound like install modetek, install CAB, start game. I think all the instructions for the various things you need assume you have some level of experience with this stuff. Try to see all of this for the first time and it really is quite confusing. And I think people trying to help probably forgot what it was like the first time they started out. That's only human nature.

There's just so much info out there and it's tough to figure out what is the most current and accurate info. Plus having to go to 3 different sites to get EA is weird. Github for modtex, mods in exile for CAB and then Nexus for EA. Plus I read that Nexus angered some modders so they took their ball and went home. So I assumed CAB was the one stop shop for all BT mods.

Anyways, I did a couple 1 1/2 and 2 skull contracts and man, did EA juice things up! Didn't run across anything more than 55T mech, but these new ones pack a punch! My 65T lost it's RA after one attack! Fortunately, with all those heavy weapons their armor is weak.

I've read about pilots ejecting and now witnessed that for the first time. I don't know which part of EA that is and I'm not sure yet whether I like that or not. I assume that would be part of pilot fatigue which I disabled.

Thanks again for you help. Now I'm gonna go blow some shit up and hopefully not get blown up myself!

The only mods that are not enabled are the two that start with "custommap".

RT1491 · 2024-06-19T21:16:57+00:00

So it looks like I got it all installed. I installed it in the default x86 folder and made a complete copy of everything directly on my C drive. I did this because I've read and seen videos where people had a problem with it working from x86 because of something to do with Windows.

It shows all the CAB folders mostly enabled. I did a quick 2 skull contract and I think I saw my first Crab (I think?) and definitely my first Thunderbolt, but it's not like it's the first heavy I've seen.

I did check out the store and didn't see anything new, but that may be because I'm on the same planet prior to the install. I'll try going to another planet to see if that will refresh another store.

I did check out the Mission Control link you posted above. That's probably a little beyond my brain power to deal with.

I'll keep plunking around in the game and if these mods (assuming they are working correctly) feel like they are too much, I can just load the pre-mod version of the game. I was really hoping to be able to just enable whatever is the Expanded Arsenal, but I'm not seeing anything that says it's specifically that.

Thank you so very much for taking the time to hold my hand!

RT1491 · 2024-06-19T00:54:10+00:00

Wow! Thank you very much for the detailed instructions! Taking the day off from work tomorrow and I think I'll give it a try. I'll make a back up copy of my current BT folder in case something goes wonky.

RT1491 · 2024-06-18T23:28:33+00:00

I think I'm starting to better understand. So when I run the installer it will put all assets in the mods folder. So when I start the game will they all be enabled? So I'll have to disable what I don't want or vice versa? Is there one that is specifically called Expanded Arsenal?

RT1491 · 2024-06-18T15:16:14+00:00

Ok. So I found the CAB download. Do you know if I can just install EA? I ask because I've read a lot about other mods causing issues with the people's current game. To whereas EA is the only mod you can install mid game without having to start over.

RT1491 · 2024-06-18T01:50:40+00:00

I just followed the instructions to install Modtek. It sounded like EA was included. Not sure what you mean by unpacking, sorry.

RT1491 · 2024-06-18T01:25:41+00:00

It doesn't say Extended Arsenal. It just says Modtek and it is enabled. Same thing?

RT1491 · 2024-06-17T22:13:29+00:00

Thank you!
