✅ - FLSun SR - First Layer curling getting knocked loose

[wise coral]

So I’ve been working on this print for a while now and I’ve managed to get one completed but imperfect print out of it, but every other print keeps failing. My first layers keep warping / peeling, and then get knocked off the print bed by the nozzle on subsequent layers. If they make it past that part, then a bunch of small knots of spaghetti start spawning. I’m assuming they’re meant to be infill since the surfaces seemed to turn out fine. The imperfect one lost few enough first layer pieces to continue, but had a layer shift towards the end. Since those last layers mostly only had certain layer types I’m assuming that was an issue with print speed.

So far I’ve attempted increasing build plate temp, increasing print temp, increasing infill, decreasing print speed. I clean the bed between attempts, have releveled the bed, and adjusted the z offset. When I realized that the weather has dropped by like 5 degrees over the last two days I also propped up some small cardboard sheets near the sides of the base, though I don’t have much else to try enclosing it with. Was considering hanging some shirts down the side but wasn’t sure about the fire hazard of it. Also considering glue-sticking next, though not sure.

My current settings are the base 0.12 fine profile on cura, with 25% lightning infill, 60 build plate temp, 210 printing temp, 70 mm/s print speed.

FLSun SR - First Layer curling getting knocked loose

[old summit]

is this the filament that came with the printer?

[wise coral]

No, it’s polymaker. But I was printing without problems on normal before I switched to 0.12 fine quality

[old summit]

I wish i could help lol, i've only had my printer for a few days, maybe try posting ur concern on the 3D printing sub reddit on reddit?

[wise coral]

Rip ok thx

[trim sedge]

On the completed print you have a layer shift. Was the print still stuck to the bed when it was done?

[wise coral]

Yes, when the plate was still hot

[trim sedge]

And have you witnessed the nozzle hitting the part?

If you try again with z hop enabled, and still have problems, its likely a mechanical issue (not bed level)

[wise coral]

not on the completed print, no. but on the fails i've witnessed it running through the spaghetti

z hop is always enabled on mine, but i'm pretty sure it's not a leveling issue

i already re-leveled it, and there's no obvious inconsistency of first layer print thickness

[trim sedge]

I mean an issue other than bed level

But im not familiar enough with delta printers to advise

[wise coral]

ah, fair. yeah i want to figure out is it's slicer settings or basic issues before i go into the whole mechanical side of things

i don't have a caliper or access to one atm, and i've never gone deep into the guts of a machine before, so i'll have to wait untill i get the right tools and have some time set aside before i try any of that

i'm currently attempting another raft print, but i don't know how that will go. i'm pretty sure that the room temp is affecting the print at least a little, but can't be sure if it's the root cause. my prints were fine before this, so i'm leaning towards not-mechanical, but you never know...

[trim sedge]

The best thing you can do is just stare at it

I can only guess what’s wrong

Looking closely, try bumping the temp up to 225. Just to see if the infill is better

[wise coral]

been doing that lol

i actually had the temp increased to 220 for a while before reducing again, and the lower temp seemed to work better. but i can increase again if this print fails

i've decreased to 50 bed temp and 200 print temp to account for the lower room temperature, to try and keep the difference from getting too large

[trim sedge]

Id also give reassembling your hit end a try

[wise coral]

mm that might be next on my list then. would a clog cause something like this?

[trim sedge]

It could. Clogs are a common cause of baffling problems

[wise coral]

/sad

making a whole list of things to try lol. recalibration, reassembling, waiting for the weather to get better...

[trim sedge]

We’ve all been there lol

[wise coral]

you wish it were a definitive problem with a definitive answer but your printer just be like 'lel no'

[wise coral]

ehhhhhh

[wise coral]

Yeah another fail

[old summit]

have u tried a different file?

[wise coral]

What do you mean? I’ve resliced different gcodes if that’s what you’re talking about. Or if you mean different models I’ve printed without problem before now

I think it’s mainly the shift from normal quality to fine 0.12 that’s causing part of the issues in combination with decreased temp from weather. I live with other people so I’m not at liberty to increase the room temp

[wise coral]

so i've attempting switching filaments (from polymaker to overture) and that's even more issues, so i'm probably going to switch back to the original filament and try on normal quality 0.2mm, just to see if it's really my room temperature causing problems, since i've moved locations and can now increase room temp a bit

[coarse patio]

I had alot of issues with creality printer on dragons. I slowed th first layers down to 10-12 mm/s and it worked for me

[wise coral]

yeah, one of the consistent adjustments i've been making is just slowing, slowing, slowing some more... didn't think it might even need all the way down to 10-12 tho 😬

[wise coral]

totally forgot i hadn't closed this yet. final update, ended up returning the roll of filament. i think it was just a bad roll, nothing printed with it came out clean
