And actually no it’s not really a difference, all printers have multiple thermistors, my Voron is actively heat , and p1 has semi active using the bed with additional fans utilizing the small chamber, the trick there is to have some airflow . The difference is the H2D does a better job at keeping it stable at 60-65 , which was my target for even stronger parts.
The text by Bambu stating to use tree supports is a load of bs, I would like a Bambu representative to come here and explain why their damn premium machine is handicapped like this, This time there are official answers demanded. This is starting to feel a lot like excuses.
And again why won’t ai detect ANY failure?
Ignore the gapping warp on the front left corner, it’s the least of my problems and no plate is washed EVERY time.
These screenshots as couple layers apart, the supports just turned into a blob on interface layers and poof, no AI detection again.
I’m getting a bit frustrated with the detection not working, anyone can SPECIFY EXACTLY what this supposed AI CAN and what it CANNOT detect? Cause they ONLY kind of failure I didn’t have yet if the whole print to snap off the bed, but if that’s the only feature working while advertising at least 2 more from what I recall (air printing, spaghetti, nozzle clumping, nose digging) I got more problems with my H2D than I thought.
Additionally this time I set the print to ONLY use one color for the supports as this job is multicolor and the failed attempt was with black and gray abs in the trees. I HAVE NO CLUE WHY THAT WOULD BE A PROBLEM , on p1 it literally doesn’t matter if I print this model with one or 8 colors. Bambu I need answers. Public answers, not secretly in a ticket. Come out and make a statement. You can’t just release a premium machine and say “yeah don’t use these utilities that are known and used by all other machines cause the premium one you just bought just run by its own rules” ….
I now you don’t want to share the file but could you tell me what is the overhang size and part size I will model it to try to see how H2D at my work does as I generally did not experience this to such an extent. I will admit I use different settings for the supports:
Sometimes I also reduce base pattern spacing and add a wall but usually not necessary with 3 top interface layers and zero spacing
he don’t want to share the file, don’t want to crop down the model and share just the relevant part by mesh boolean, don’t want to adjust settings, he only want to tell us that the AI doesn’t detect and the support fails on this machine, that’s all.
In case you didn’t already realise, I’m just ignoring you. I don’t know what you are doing in my thread, I made clear I don’t like you and I don’t want you here
oh you mean the once in a six side video! haha as a fellow aussie I apologize but no his video on that was flawed, he was basically insisting the same ideology of “default settings should work on bambu machines”! as if bambu is a magical company that it pretended it was lol.
But, no, it’s not. It’s not a magical company that can just dial in everything for us. I watched his video, read his reports and stuff, didn’t leave a bad comment in his channel I just left as I knew the 0.2mm nozzle profiles were fked, and it’s a real struggle to get everything back on track with 0.2mm nozzle. And to be honest PVA on 0.2 was never a good idea anyway (soluable PVA is too soft). Instead he should be using breakaway support filaments, like the Support for PLA (much stiffer and can be used reliably). I am not familiar with Support for PLA/PETG, which I heard that has caused some issues for others. I was just using the old batch I had and never had a issue with that.
There was a bug about the slicer back then that’s true, but my support interface (even with support material) doesn’t fail me anymore now, as long as I remember to also reduce the bottom interface gap to 0.
0.2 is not the only child that Bambu is ignoring. 0.6, 0.8 profiles also suck. 0.4 HF profiles suck as well. They didn’t even bother to test the max VFR for many other compatible filaments they have. They just kept it the same as the standard 0.4 nozzle. I can’t say that they’re lazy, but they’re definitely very slow on these “less prioritized things” and always put paid beta products out too soon.
Fascinating issue you’re having - I can’t say I’ve had any support failures myself but I’m also not ironing parts above the supports.
I would think the gcode generated for the H2D and the P1 would be similar - and the differences would be the start-up code and the like [stuff that’s printer-specific].
So why it’s failing in the H2D is … definitely odd.
Just for S&G have you tried using something like HIPS for support with a 0mm top interface? That’s what I’d do.
P1 and Voron are not heated chambers, H2D is - perhaps the supports are staying softer on the H2D and as a result not supporting as well?
Will be curious what it ends up being when you figure it out.
[I did try to read every reply to this thread, but if I am suggesting anything that was already suggested - I apologize.]
Wait until your bad luck come with something shiney black
The general consensus here is that the AI is terrible at detecting shiney black prints, it’s either overshooting or undershooting. And if you print organic stuff a lot, other colors might get targeted.
For me, it’s just the fault of the side window causing too many visual distractions. The camera can see through the window glass, and the window glass could be green as well, the lighting could be green, could be coming from the top lid, could be…
And it’s using a chipset from 14 years ago glued with a cheapest NPU available on market (a sbc with 2Tops NPU costs something like 40USD when bought from aliexpress, and that thing has a a couple times more powerful CPU and more RAM)
It is definitely a design flaw, I see no possibility of this working reliably even 3 years in the future with all firmware updates.
No worries too much info here , you WILL miss points . On P1 yes though it’s semi active (I’ve modified the bed to use heat sinks and fans for the chamber. My Voron is actively heated.
I’ll try with different support materials soon !
Yea, this thread is just pure entertainment at this point. Its just a big rant post that subtly implies a willingness to engage in troubleshooting, but then gets condescending and flips to bashing his $2500 printer… I think the guy either works too hard or is bipolar.
Or both… rn I’m closing on 30 more straight hours in the lab. I mean you would too if what you paid for is not working as intended , and I already knew my options if I wanted to tinker for such basic things.
I will troubleshoot the damn thing, no question about it, but that’s just not the “package “ that was advertised to me and I paid for, if you get what I mean. So while I make progress on this, I’ll try to get as much attention as possible, because Bambu needs to adress this.
Perfect out of the box doesn’t imply 100+ hours of experimenting just to get normal supports to function as expected
