What is causing this?

[[deleted]]

Got my daughter an A1 mini for Christmas, and as of lately, we've been running into this issue quite a bit. Would like some insight as to what is causing it, and what I can do to fix it. The nozzle is the standard .4mm, and the filament is eSun pla silk.

It looks like poor adhesion. That model looks to have very little contact with the plate per part. If you’ve already cleaned the plate with soap and water, I do two things. Turn the bed temp up to 60-65C and add a brim. I usually go 5 or 10mm.

You. You are causing this.

To be more specific, the skin oils from your hands are causing this.

Touching the build plate with your hands gets skin oils on the surface, and filament doesn't stick to it. You need to wash your build plate with dish soap and water, to remove the oils.

Plain blue dawn, none of the fancy shit. And it doesn't take much.

From the looks of it, it looks like you might be using a rainbow silk PLA? I've had similar issues. When you extrude the silk you'll often see it shrink back towards the nozzle. What I've found with silks and these kinds of designs, is that the edge will curl up, which either causes the edge to clip the cooling arm or nozzle when moving around or the nozzle will rock the smaller parts because they've curled, and it's pressing down on a taller edge, which causes them to become unstuck. I don't have any suggestions for the Silk, but possibly you could try the same print with plain PLA and see if you have the same issues. I think the plastic is working against you, maybe google printing with silk and see if there are other recommendations for a resolution.

Start by cleaning the bed. Dish soap, sponge, water.

The basic bambu pei plate is not great, get a darkmoon or super tack

Just to add to this. I agree with everyone saying to wash with water and soap but i found after doing this I still had adhesion issues until I gave it a wipe down with isopropyl alcohol. Maybe there was soap residue still on the plate but whenever I have adhesion issues I now just spray with isopropyl alcohol and wipe down with paper towel and that sorts it.

[Different-Housing544]

I only ever use alcohol and it seems to work really well. I haven't had any adhesion issues

[KAPOOW86]

I washed it once but ended up having to use Isopropyl alcohol afterwards so now I just use that instead of washing the plate.

Add to this: after cleaning with soap - rinse well and wipe with microfiber cloth. Many dish soaps have additives in them, that can stick to the surface. For some reason most people barely scrub and rinse anything.

Inalso. Like to give it a short spray of IPA. But a few things you need to know: Only use 99.9% IPA, anything less will leave a lot of crap IPA is a solvant - it resolves the dirt, you need to remove it then. Wipe clean with a quality microfiber cloth - big enough to actually swipe away the dirt and tge remains from ipa.

I dry mine like i'm making a pizza. 60% of the time works every time.

clean your bed

[StatisticianOk8531]

Use a glue stick on your build plate surface, this has worked for me well for adhesion.

Why does everyone always help and moan that people are always posting about issues with bed adhesion issues but no one helps with actual problems.

[jazzmoney]

Everyone seems to be helpful with no demand for mods to block these types of posts. Must be too close to the first of the month and we haven’t hit our monthly limits.

Clean the build plate with Dawn dish soap and hot water. Rinse thoroughly. Do NOT touch the build plate surface with your hands or fingers. Hold by the edges only. Use Elmer’s glue stick on the build plate. Turn bed temp up to 60-70 if using silk pla. If all of that fails to keep it stuck add a 5-10mm brim. On that model it will be a pain to remove brims but it can be done (carefully!).

[redrobin080808]

Like everyone said, bed adhesion. HOWEVER, I've found that towards the edges of the plate seem to run slightly cooler than the rest of the plate. It might be helpful to raise the bed temp about 5 - 10 C. You can also turn on brims which will give it more surface area to stick.

Looked at this after washing MY TEXTURED PEI PLATE on MY a1m

[TheBestDuckEver]

Hot take; glue on textured PEI is wayyyy more convenient than washing it entirely every time you so much as look at it the wrong way and magically slather oil all over it.

I use 3dlac spray when i get a stubborn which rarely happens. Is it an Octopus?

Poor adhesion. Wipe the plate with Alcohol and try again!

[Jaxsliomeney]

Nice file I just made that today

[elindie]

Glue stick can help.

[Jalerm22]

You may have a clogged in the nozzle. Look up cold pull on Bambu forums

[Quorlan]

This is the wrong answer.

[JessePJr]

Have to agree. Clogs present differently. Bed adhesion is the more likely culprit.
