I posted this post on 3D Printing@lemmy.ml and cross-posted it to 3DPrinting@lemmy.world, and apparently it made it to neither.
For the lemmy.world community, I’m not really surprised. I simply can’t create any post on any lemmy.world community from SDF. None of my posts ever shows up there for some reason. But I’m more surprised that it doesn’t show up on lemmy.ml: usually I have zero problems with that instance.
So I’m wondering if there’s a problem with federation or if it has something to do with the large number of photos in my post.
Anybody knows?
Hmm, odd. I just posted to .ml with no issues.
This isn’t the chemical polishing post so nobody else gets confused - dullard just posted twice.
Yeah lemmy.ml is usually no problem. But not this time. The only difference I can think of is the number of photos in the post. Maybe it’s not acceptable? But it seems to go through just fine on the SDF instance.
I can see this. And I’m in world. World does have some strangeness when it comes to sync sometimes. Peertube still doesn’t work with it. But mastodon does. Might be related to the version they are using?
I can see this. And I’m in world.
When you mean “this” you mean this thread about federation issues on SDF, or my post that apparently didn’t make it to 3DPrinting@lemmy.world? Because the former was created on SDF - which always seems to be visible from other instances - while the latter was created from SDF in a community on lemmy.world, which rarely works for me.
This comment here. I wish I had visibility to the logs.
Probably not too helpful but it does appear that you can post via world and back again.
I tried several things:
- Hosted all the images on my Pixelfed rather than directly on lemmy.sdf.org: no joy
- Replaced “El-cheapo” by “Cheap” in the title, in case lemmy.ml has some overly-busy PC filter and “el-cheapo” is now considered offensive or something: no joy
- Finally, I removed 2 photos to keep the total images in the post to 10: it went right through on lemmy.ml
So it’s the number of images. Apparently more than 10 is not okay with all instances. Good to know if you ever want to make a photo-heavy post too.
I’ve also cross-posted this successfully to lemmy.world. First time in a long time. And the only real difference with all my previous failed posts that only had one or two images is that the images aren’t hosted by lemmy.sdf.org.
So it would also appear that lemmy.world doesn’t like posts with photos inlined directly on the SDF instance.
Thanks for sharing your findings. Did you try these things more than once, on different days, to make sure the triggers you think you found weren’t merely coincidences?

Yeah I did many posts over months on the lemmy.world 3D-printing community - and other communities too. In the best cases, the post went through 2 or 3 hours late. Sometimes up to 2 days late. Usually it never goes through though.
I usually post things with pictures, so I always have at least a thumbnail picture that I uploaded direct on lemmy.sdf.org.
This last post I did had a thumbnail hosted on SDF’s Pixelfed and it went right up.
As for lemmy.ml, I never have problems with it. It’s just this one time because I hit their images limit - that I wasn’t aware of and is documented nowhere as far as I know.
Our little instance often has federation problems. Sometimes they’re obvious, and sometimes more subtle. Sometimes it eventually catches up, but I suspect not always.
I don’t know what causes the problem, as I have no visibility into the systems. The person (people?) running the instance doesn’t communicate here, so I think you would have better luck investigating by signing up for shell access and asking in the bulletin board there.
For what it’s worth, my recent posts from here to lemmy.world communities seem to be getting through, as they have comments from lemmy.world users. Example 1, Example 2.
I think I finally found the problem with lemmy.world: that instance doesn’t like posts with images hosted on lemmy.sdf.org. Not comments mind you, those are fine. Just posts.
As for lemmy.ml, it won’t accept posts with more than 10 images - although they’re fine on SDF.
See here.
I do have a sell account and I’ve tried getting help from the bulletin board several times years ago. It was crickets, so I gave up.
