I just realized that Bambu Slicer doesn’t offer suggested fixes to potential problems with a sliced model as opposed to PrusaSlicer. Normally with PrusaSlicer I get a warning and a suggested fix like adding supports etc while I don’t with Bambu Slicer. I was trying to print a saucer and it kept failing (2 times before I figured it out) because it needed supports. And PrusaSlicer doesn’t have a printer profile for any Bambu printers as far as I can tell. Does anybody have a custom profile for the A1 Mini and the A1?
Thanks
Ok, so try to slice this with the default settings for an A1 Mini with PLA and a 0.4 nozzle. It doesn’t show any warnings for me? Just slice the saucer.
Doesn’t need them.
I tried printing it twice without them and it printed about 16 layers in an open circle and then when it went to try and print in the center it was 16 layers high and made a mess with no bed adhesion. Added supports and it prints fine. It was printing in the air above the bed. Scroll through the sliced print between layer 16 and 19 and you can see the likely issue.
If you’re getting bed adhesion issues that is as likely to do with a contaminated build surface than slicer settings. Have you properly cleaned you plate and then verified that it is truly contaminant free by performing a first layer test?
Since you’re build problem appears to be remedied by supports, that leads one to look at stiction as the culprit. Also, have you experimented with brims? Even on a dirty plate, brims can compensate for a multitude of sin as they also perform a similar function as brims when it comes to plate adhesion.
Yes even though the build plate only had 2 small previous prints on my new printer, I went ahead and washed the plate with Dawn soap and hot water again. That was not the problem. When I printed it with a brim and supports the first layer was perfect. If you slice the the file and look at the layer info it puts down 16 layers in a larger circle with the center empty and then it tries to do the center but the nozzle is already 16 layers too high.
How do I add images to my post?
I get it. It’s the bridging across the bottom and not the handle.
I can’t say why that particular model isn’t triggering support for that bridge. I doubt though you’ll have that as an issue on all models.
the icon horribly circled will become available after you hit user. Just read a bit more and keep posting. It doesn’t take long.

Thanks for confirming my issue. 
Now I don’t have to post images. That said, how do I post images in my post for future reference?
Thanks
Edit: I see your answer above after I posted this. Thanks!

yeah, he’s having issues with the bridge on the bottom of the cup that forms above the intital ring.
Yes, if you scroll between layer 16 thru layer 22.
16 through 22 but at what layer height 0.08, 016, 0.20 etc?
The layer height will vary depending on the process profile.
Wait, did I miss something. I thought we were talking about the saucer.
lol, no I guess I missed it. My bad.
I was using the defaults and it was 0.2mm layer height with a 0.4 nozzle.
Well I guess the saucer has a similar design. 
But I was curious about what handle you were talking about.
The cup, which makes no sense when you’re talking about the saucer. I swear I can read and comprehend. Maybe not both at the same time…sometimes.

I decided to load the saucer into PrusaSlicer and slice it to prove the whole problem exists in Bambu Slicer not warning about problems. Bambu Slicer throws no warnings. Issue verified. So how do I contact the developers about this issue that exists in Bambu Slicer?
Edit: I found the bug report thread so I can post my question in there and see what happens. I will do it later today.
I’m struggling to understand the logic behind concluding this is a bug in Bambu Studio. Just to be clear, I’m not a Bambu fanboy, but your argument seems to rest on a flawed premise: that Prusa Slicer’s behavior is somehow equivalent to Bambu Studio’s. The issue is that Prusa doesn’t even have a definition for a Bambu printer, while Bambu Studio does. Comparing the two in this context doesn’t make sense. Can you clarify how these slicers are related in this scenario?
Also, why did you check that this was solved when you clearly are continuing the dialogue in this thread. Do you realize that this thread will autolock because you flagged it as solved? You run the risk of prematurely cutting off your own discussion. If that was not your intent, I’d suggest you go back and uncheck that box.
