#odd first layer
balmy nymph
Did you load/change filament right before that print?
@boreal oracle also, do you have an STL I can take a look at?
boreal oracle
No, I'd done a print before that. And it lays down the outer rim of the first layer, then fills in the lines, and it did the outer part no problem... And I know it isn't the STL because I've done this one several times with no issue
balmy nymph
OK. Then I am wondering if maybe you did have the nozzle too close. That first layer looks pretty compressed.
boreal oracle
Here's the set anyway
balmy nymph
which piece were you printing, and which slicer do you use?
boreal oracle
I've been getting perfectly smooth first layers of the correct height, and if it were too close, it would still have extruded
It's the "deep drawer", Cura
But if it were an STL or slicer issue, it would have done it on the previous run or the current run
It definitely just didn't extrude part of that layer
balmy nymph
the weird part is that part of the logo is also missing, even in the sections that did extrude
boreal oracle
If it had extruded, and been pushed away, it would have been embedded somewhere else in the print
Well, the logo might be because I changed the scale a tiny bit? Not sure
balmy nymph
I'm thinking it actually picked up something from the logo that didn't attach, then dragged crap around on some of these.
that's the only thing I can think of here...
Do you have a timelapse you can check to see what it did?
boreal oracle
I do have a timelapse, but not sure we'll see anything. But again, if it had dragged it, it would be embedded elsewhere in the print
balmy nymph
I've had similar things happen on my Ender 3 V2 glass bed. That thing is fickle.
boreal oracle
There's just no material there
balmy nymph
Which bottom shell pattern did you use? Rectilinear?
boreal oracle
Lines
balmy nymph
I actually switched to a PEI bed because that glass bed made me mad. It would work great some days, and then others, it would be weird. I am going to assume it had to do with ambient temperature and humidity in my office.
boreal oracle
It just doesn't show anything in part of the logo
balmy nymph
Yeah, that's weird. From the way that bottom looks, it didn't lay down lines there, or, they were moved...
what resolution did you use?
on 0.16mm in PrusaSlicer, it looks like this...
balmy nymph
layer height
boreal oracle
Yeah, 0.3mm
balmy nymph
yeah
boreal oracle
It has to be an extrusion issue -- there's literally no material anywhere for it to have been an adhesion problem or something
balmy nymph
unless you did something with the filament loading/unloading/extruder, the only explanation I have for that is that when your printer was laying down the bottom layer, it laid down a smaller piece in the center, managed to get it to peel from the bed, and then picked that up, and it cascaded. Usually that doesn't get incorporated into other layers...
Oh. One thing. Do you have a filament dryer?
boreal oracle
If a piece got picked up, but wasn't embedded in the print, it would have been off on the side -- material that pulls up doesn't just disappear. But I've had perfect adhesion on every print
Well, almost
No filament dryer
boreal oracle
Temps between 60 and 100F, humidity between 35 and 65, but not sure what the actual average is. Filament is kept in a bag with a desiccant pack when not in use
balmy nymph
What printer/extruder are you using?
boreal oracle
Ender 3 V2, stock
balmy nymph
does it ever make a ticking sound when feeding filament?
boreal oracle
Not that I've heard
It's basically silent with the exception of the fans whirring and the limit switches clicking
balmy nymph
hmm, OK... I have a dryer and if I run that too hot on PLA, it'll soften the material to the point where the extruder has issues feeding.
hahaha, OK, so you can't say the opposite of heaven on this server
boreal oracle
I'm wondering if something made the filament slip just for a little while
balmy nymph
I was like, why is my message being deleted over and over again?!
boreal oracle
Lol, no, you can't say h e double hocky sticks
Basically anything considered a swear is blocked
balmy nymph
I was just saying, I'm in a state where it's hot and humid.
balmy nymph
I was saying that NC was heck-adjacent.
boreal oracle
lol
balmy nymph
😄
This is such a weird result. I am freakin' intrigued. If you ever see any repeat of this, will you ping me?
boreal oracle
Sure, if I remember, lol
Oh, I did have one where it just totally stopped extruding and ate into the filament... I was able to restart with no issues
balmy nymph
Like, all I can think of, and based on personal experience with the Ender 3V2, it didn't extrude because the nozzle was just too close, there was a clog (but how did it get resolved?), I had just changed filament and didn't extrude enough, or the extruder didn't feed filament properly because it was slipping.
Hmm.
Where is your filament roll? On top?
boreal oracle
Yeah
balmy nymph
Do you have a filament protector around the Z axis screw?
boreal oracle
I do not
balmy nymph
maybe try that...
boreal oracle
Got a link?
balmy nymph
maybe it picked up lubricant from the screw...
one sec
something like that
there's a bunch of remixes, too
boreal oracle
I'll give that a shot
The placement of the filament hole SO CLOSE to the Z screw is one of the things I do not like about the 3 V2
But I love the bed
balmy nymph
yup
boreal oracle
It's so nice to just pick prints up after they finish, lol
balmy nymph
I was not impressed with the bed.
I actually switched to a dimpled PEI plate.
And, it's a beast. Everything sticks, no matter size. And it'll all come off once it's ambient temperature. Even with like 10mm brims.
boreal oracle
I basically get perfect adhesion and prints do not stick when it cools down at all
balmy nymph
nice
it could be I messed my plate up by wiping it down with acetone a couple of times
boreal oracle
And I leveled it manually >:3
boreal oracle
I should say, I do it by eye
balmy nymph
But, I am not leaving anything to chance if I am printing for longer than 5 hours.
boreal oracle
Most of my prints are a few hours XD
These bigger drawers are a few hours a piece, currently doing 2 of the shell thingies, 9 hours
balmy nymph
I am currently printing a present for a friend who's building a Gundam gaming rig. It's a Gundam bust. Some of the parts took upwards of 15 hours to print.
boreal oracle
Nice
boreal oracle
Oh wow, gonna paint it up like that too?
balmy nymph
I am printing in Fillamentum ExtraFill PLA Vertigo Grey, and it's coming out amazing.
Oh, yeah. Painting, all that.
boreal oracle
That's gonna be sick, your friend is gonna freak!
balmy nymph
sooo much support material, though, hahahaha
I think my total print time now is around 40+ hours.
boreal oracle
That support life is hard
balmy nymph
I printed one at 100% scale to make sure it all fit together, and they did a great job with the model parts.
boreal oracle
I have a lot of supports and scraps laying around that I need to recycle DX
balmy nymph
I don't even know where/how to recycle.
boreal oracle
Well, you can throw it in the recycling can, but I'm building machinery to do it -- chip it into pellets, melt it down and extrude it into filament again
balmy nymph
oh dang
boreal oracle
Going to see if I need to treat it at all; if I do, I have a vat I can melt it down and chemically purify it
Do not attempt at home, I am a professional crazy person XD
