I benchmarked 6 different metal USB sticks in c/[email protected]

I also have a DTSE9 and it's been on my keychain for at least 10 years now :D

Recently I have just gotten 2 nvme ssd enclosures and have been very happily using them for the super quick image writes. I just checked if there's some compact 2230 enclosures and some of those even have keychain attachment points.. they definitely are a bit bulky for a keychain but I'd argue they still are an option and will look similar to a keyfob :)

How big is the Bambu A1 with AMS? in c/[email protected]

[–] [email protected] 1 points 8 months ago

It's a wobbly affair but it does work and Bambu does offer it as an option with a mounting bracket you can print. I.. just put my AMS to the side because my table is already kinda scuffed :D

So glad I'm ditching these fucking idiots in c/[email protected]

But does it splatter better than Vegemite?

Don't bring the marmite into this!

Blobbing on outside walls Bambu PETG Basic, drying issue? in c/[email protected]

well it was less underextrusion and more the printhead just trying to go supersonic at those spots and the material just didn't flow fast enough :D

I also figured out, I can adjust the max volumetric speed of the PETG filament settings and that will limit the wall speeds autumatically

Edit: This turned out to interact weirdly with layer height changes, I ended up just reducing the max speeds.

Looks like the default speed settings in the slicer was just too fast :D

So yeah, that solved it! Set it to 50mm/s maximum and it just disappeared! Thanks for the suggestion :)

I just spent some more time observing and yeah, the printer tries to go super sonic for the walls there with up to 150mm/s :kekw:

It's kinda not at the start or end of the layer. The layer starts with the inner wall, which prints fine and then it does the outer wall which doesn't do fine.

Which corresponds to the wall here

What slicer are you using?

Bambu Studio 1.8.4.51

Thanks for the input!
So the thing I was trying to print was this: https://www.thingiverse.com/thing:6365845
Ideally you'd just print it in PLA but I only had one colour PLA so I thought, might as well gather some PETG printing experience :D
The part in question is red_panda_low_poly_V1_-_head_A_red.STL and I tried to print it on an odd angle to make sure that most of the outwards facing walls were on the top, because anything that needed support turned out so hideous.

Also it seems to appear on any side of the model, where you have a slight overhanging angle, in no particular axis :)

I'll print it in pla once my current print is done :D

Edit: Setting the max speed for walls to 50 mm/s solved it! I feel like this should be limited when you select the filament, but oh well.

Hey, so I have recently gotten a Bambu A1 and got a roll of PLA and PETG. The PLA is printing very nicely out of the box but the PETG not so much. Since I'm still very much at the beginning of my 3D printing journey, I don't really have a good way of drying my PETG yet, I just stuffed it in a plastic ziplock bag with all the desiccant bags I got from the rolls and printer and stored it that way. I'm already planning to print myself a filament enclosure, I just haven't gotten around to buying the bearings, etc for it.

I've done some functional prints with no angled (overhanging) walls and they have turned out pretty good. When printing on supports the overhangs are ugly af, but no weird pattern like this.

The issue I'm tracking down seems to occur on ~60+° overhangs, that really shouldn't be an issue. I've done a sliced test print and took some photos, any idea what causes this?
Thanks :)

Some settings I played around with was flow rate (0.94->0.95) and layer height (0.2mm -> 0.15mm) but it seems to make no difference.

(note, on some of them the part is photographed upside down.)
