overview for Jawa

I benchmarked 6 different metal USB sticks in c/technology

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/3dprinting

[–] Jawa 1 points 3 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

I apologise if this is already common knowledge, but I just found out you can have multiple layers of LUKS encryption on a drive! in c/[email protected]

Ideally you would never have to because you just have the two people come up with their part of the password and then initialise the LUKS partition together. Sorta like a key ceremony

You can also just split the password for a single LUKS into two parts and give one each to the two people :D

So glad I'm ditching these fucking idiots in c/3dprinting

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/3dprinting

[–] Jawa 2 points 10 months ago

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:

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.
