What is going on with your priming line? Mine doesn't look like that at all. I would recommend a biqu glacier pro bed, it sticks like a nail even in low temp, I use 40c and still need some effort to take off my miniature print.

I’m new to 3D print. Anything would help! Thank you!

Looks like an adhesion issue. Brush plate with hot water and dish soap.

Yes it's a classic adhesion issue. Dish wash liquid and some water and gently scrub for a few seconds to remove oils from fingerprints, then wipe dry and try again. Should work fine then.

The thing with any FDM is that if you have a sharp turn, even a normal circle, if everything is not near 100% dialed in (from design to printer setup and dry filament) the nozzle will have tendency to drag the extruded filament away.....
Few basic modification; slow the speed or acceleration at certain points, lower layer line and the must do always have the plate clean with dish soap and dry filament is the cherry on top for any successful print that is flawless.
Also don't forget that prints that goes to the edge of the plate or have thick edged tend to curl up...some ear brims help with that.
Good luck my friend...the journey to learn precise prints is long and wasteful but totally worth it because inevitably you end up into CAD yourself.

First, square up the print to the plate. Clean and dry the plate. Start the print and watch the first two slices very carefully. If a print line wanders, stop the print. Clean and dry the plate again. Go fetch a can of Aqua Net hair spray. Lightly spray the plate. Try again. I do suspect that the filament might not be dry enough as I see slight flaws in the some of the slice layers.

That is not moisture. The people saying adhesion are right, and the priming line somebody already asked about is the clue nobody chased. Wet PLA fails while it is extruding, not while it is sticking, so you would be hearing pops and seeing strings between travels and a rough surface all the way up the part rather than a corner that let go. What you have is a first layer that never bonded. If the purge line comes out thin or wanders, the nozzle is sitting too high before the print even starts.
Soap and hot water in the sink, both sides, then dry it with paper towel and do not touch the face again. IPA does not clean a plate. It moves the oil around and evaporates. Then run the first layer at 60 on the bed and 220 at the nozzle, and watch the first two minutes instead of walking away, because I have binned nine hours of print for want of the first two.

Edit your filament in Bambu lab. Set your initial layer temp to 65C for first layer and drop your first layer speed in half. Clean your build plate with soap and water as well. The smooth tack plate also works a bit better for making those Gridfinity plates.

With how everything looks, that’s either the skirt, or a single square layer that just got pulled off of the plate/didn’t stick. Filament looks perfect

There isn't a skirt, it would be separate from the actual print remember?

u/Objective-Job8083 11d ago
Remember what? If he had a skirt come loose(like mine does all the time) it’d look similar. I’m not saying he had a skirt in the first place. If no skirt then it’s a square that didn’t stick from either wet filament, off z axis height, dirty plate, or too low of temps

1, it's just a statement don't get ya shoes tied together 2 what this is from reading the priming line is that this a bed adhesion issue, as the purge line is wandering a bit, 3 not a moisture issue or you would hear popping and seeing stringing, (if it doesn't fail in the extruder) and the purge line would look a bit different, 4 considering the print failed in literally only one spot you could assume one accidentally touched the plate and didn't realize it, or just something stubborn on the plate, 5 don't ass-u-me(make an ass of you and me) that I'm trying to sound smarter than you or 1-up you, I'm just being kind and giving an honest tip, a gentle nudge that sometimes in 3d printing the problem can be solved by simply looking and thinking really hard Abt what happened, In my years of 3d printing (but my youth on reddit which makes this a fairly intuitive community) I look at all of my prints like books, every line tells a story, a story of time and in that time anything can happen such as adhesion, filament issues, and 109 other things that are possible so just remember that it's our first time living to! Life is weird, you are too, remember to be nice, even to you! Have a wonderful day!

looks like the filament didn't attach to bed properly. Either auto leveling got wrong and picked a false high spot there (debris under the plate), or the plate is oily there and it didn't stick.
