Man, my A1 printer s been slacking recently, that texture plate bro dosen’t let my material stay on it. They get dragged across the plate and becomes a blob of coglomerate of extrusion on my hothead. I checked filament,four of them, all different brands, bambu, polyterra, esun, elegoo, worked for the first half of the spool, the plate is clean, i clean it with Palmolive, my RH is constantly 30%. What could be happening, this is crazy.
What build plate are you using? Have you tried adding a skirt and even reducing the speed of the first layer? BBL recommended me do 15 and 45 on the print settings
Just the typical textured plate that comes with any Bambu machine
I’m assuming you didn’t change any of the default settings, but I’m going to provide you with a step by step to get you to find the source of the problem
First, heat up the bed to your normal printing temperature (typically 60C) but if it’s lower, go ahead.
Then. check the bed extremities after 5-10min to see if the bed heating somewhat evenly, by just touching the bed on its corners.
If you have your windows open or anything like that, it will affect the temperature in which you can print substantially. You, have to have a temperature that is high enough for this to happen, if your climate is too hot, you might have to lower the temperature via aircon or increase it higher (I wouldn’t know, tbh), my climate is cold (around 5-15C) so I can’t print under 45 below 15C)
Next.
Don’t use your usual model,
Print cubes by using the primitives under the right click on the build plate of your slicer.
Place 5 of them, one on each corner and then one in the center, and see which ones will come off. This will help you tell if it’s the model you’re trying to print or if it’s the heat bed.
Next.
Under the filament settings > Cooling > No cooling (change to 3 layers), then, under the speed settings of your Global project settings (not object), change first layer speed to 15 and initial infil to 45.
As far as the bed plate, just try some IsoPropyl Alcohol, get some spray bottle from the grocery store, empty it, rinse it, and fill it in with the aforementioned IPA and don’t use a towel, use a paper towel or use the heat of the bed to dry it out.
And remember to use a glue stick.
Once you try these things let me know what you find out.
TIP: If you find that after washing it works and then it stops working, then it could be dust, watch out for dust where you live and try to place some kind of fabric enclosure onto it just to block it ou.
Extra TIP: If you find that increasing the bed temperature is the thing that does it for you. Then make sure to enable elephant foot compesation, .3mm by 3 layers or something like that.

I disagree, not what I’ve found through my testing, using IPA only improved bed adhesion over regular prints requiring nothing but a spray and not having to use multiple wash cycles after couple of prints.
Although the whole Micron dirt could be true, it is definitely a non issue.
Yes don’t use IPA on the SuperTack, or better yet, don’t get them, the forum is full of people with issues caused by them.
And OP just said he uses PEI.
ipa does not do the job. i used to use it and always had adhesion issues.
i got me a bottle of dawn powerwash and a scrub daddy. use a few squirts of dawn and warm water. you will see the water turn brown with dirt and oil. after washing, dry with a lint free towel and enjoy the awesome adhesion. perfectly smooth first layers

Really? that’s a first for me, it always worked so well with me… interesting

it does work, for a while. it spreads the oil and dirt around to make you think it is clean. its called diminishing returns. it becomes less and less effective. the real solution is washing it like suggested above. before i knew about the dawn wash, i would replace my plates every six months or so because the prints stopped sticking. i used ipa exclusively. the last plate i though was bad, i washed and it was like new. i have not replaced a plate since.
all in all you do what you want, if it works for you thats awesome.
just trying to educate the new people that are having issues.

dawn is one of the best oil and grease solutions that is made. they use it to help save wildlife that gets coated in crude oil when a tanker or rig has a spill.
honestly any premium dish soap that works on tough grease will probably be fine. i once used hand soap in a pinch at work and it was fine for a few prints.

@A1Mini_Prints It accidentally works the best. just…one of those annoying life things.
Legit? any brand of really good dish soap will work - dawn costs us nearly 5 bucks a bottle because brand etc…so we do eat the costs while we drone on about it.

GLUE STICK ? i bought this printer, to avoid glue, and was told by many, oh no, i never need glue ??? what ???
I like the cubes on corner and center trick.

I know, “get a different plate” is not the answer most want to hear, but for bed adhesion issues, but in this case, its true. I had a few prints starting to fail in the first minute of so. I kept hearing about the CryoGrip plates from BIQU. I bought the less expensive Glacier plate and havent had an issue since. Im not saying its the magic pill for printing failures, but its superior to the PEI plate. I print a lot of PETG, PLA and some TPU, and all 3 stick great. I cant get the TPU to do the 45* test, but it works great for my stuff.
Glue may be a pain to use but it’s kind of a cure-all since it becomes what a model sticks to instead of the actual plate. I’m doing prints with lots of tiny multicolor details and my plates have lost enough tack that there are fairly frequent 1st layer issues if I don’t use it. If a model is expensive in time or plastic I don’t risk it and use glue. And my approach changes depending on the print. No single 100% solution for everything. Some stuff prints fine without glue too especially on new plates. But to each their own. Just my experience.

When a print lifts up in the corner or small parts don’t want to stay put on my BL, PEI textured plate, (my go to plate) which by the way happens very, very infrequently and who knows why, maybe a cool spot on the bed heater or a breeze blowing over the plate. i will use the “chap stick” glue stick and then reprint. I tried the green glue once and it did nothing so haven’t used is since.
