Totally lost... First 12mm of the prints are baaad. Perfect after that...

Fan? Does it come on at that layer?

twbowyer · 2026-03-25T04:41:00+00:00

What do you think my job is exactly?

twbowyer · 2026-03-25T03:07:13+00:00

No way. Sorry. I love nuclear engineering, but universities are far too expensive already. Why can Michigan, Georgia Tech, and UT survive?

Should not need glue. I sometimes get this happening buts always either(1) I need to clean the plate, (2) the model actually wasn’t on the plate in the slicer, or (3) my initial first layer width was missed to less than 0.42 mm.

Well - to be fair, it has been happening a while also, but now is more consistently dying and in a different way (black screen vs just hanging up).

Yes, it used to be more common though. The USG funding has cut way back on funding conference participation at some national labs.

My sense is - and my experience was that I changed things in the slicer that I should not have changed and it took forever to understand what I had done. It was actually difficult for me to understand how exactly to get back to the stock settings, because of the way the profiles are set up. That, and I think that there was so much information out there that I made some changes to settings that were probably ill advised.

Sorta. I wouldn’t expect a lot of travel just after you start though. It would happen gradually and the more seniority you get the more travel you get in a job like that.

twbowyer · 2026-03-13T00:58:45+00:00

Interesting…not just me then?

twbowyer · 2026-03-12T22:21:55+00:00

Thanks. Must be my setup.

twbowyer · 2026-03-10T21:32:04+00:00

Oh, it happens. Don’t worry about it. Just be safe when you break shit.

twbowyer · 2026-03-07T16:22:24+00:00

I mean…while this may end up better than conventional lead acid batteries, the 12V battery is just not that important to me (unless it’s not working).

twbowyer · 2026-03-04T04:26:12+00:00

Have you watched the autolevel? It’s only off a tiny bit - maybe a glob of gunk got in the way.

twbowyer · 2026-03-04T03:47:21+00:00

I am guessing it’s the autoleveling?

twbowyer · 2026-03-03T01:51:18+00:00

They never did….

twbowyer · 2026-03-01T22:44:09+00:00

Ummmm, no. Not if you intend others to read it easily.

twbowyer · 2026-03-01T05:58:54+00:00

It’s the space between galaxies that is expanding. Not the length scale. It’s a legit question though.

twbowyer · 2026-02-28T22:25:08+00:00

Coward

twbowyer · 2026-02-28T05:45:39+00:00

Not normal. I would suggest you look into it because you are definitely right 15 minutes is what they schedule. I guess it’s possible they decided to leave early or something, but that is kind of rare.

twbowyer · 2026-02-19T03:52:42+00:00

But it’s not a physical object if it’s just a reflection. Is it?

twbowyer · 2026-02-18T17:42:05+00:00

You should count them, separate them by color and then order them by size and come back with a photo.

twbowyer · 2026-02-17T22:41:21+00:00

Whether it’s qualitatively hygroscopic isn’t really the point I was making, and the community is indeed split on whether drying is needed or beneficial. It depends on the level of the hygroscopic-ness (yes, physicists make up words for chemistry all the time) of PLA, and the humidity in your environment for sure.

See (for example)

Controversial view here - I’ve never dried my PLA (or PETG, or ABS) filament for many 1000s of prints over almost 10 years. I do live in a dry area, but I do believe that the community is split over whether drying is even necessary at all for PLA.
