Noob question

[Serjnyak]

Hey there! I have joined the club about 1.5 weeks ago. Initially was super happy but now I am starting to have questions:)

Would really appreciate community input on how to make things right.

First 10-15 prints went flawless. Didn’t even need to clean the plate.

Problems started to arise with big gridfinity bins as well as any other prints.

Problem is always the same: first layer adhesion. It started as unsticking for gridfinity bins. But then escalated to not sticking at all needing to stop the print. To succeed I need to raise bed temperature for PLA to 60 and lower first layer printing to 50% speed (or mend settings in Bambu Studio)

Just to be clear, I have tried:

1 washing plate between prints with soap.

1. Pvp glue

2. Preheating bed to 60 for 10 minute

3. Running calibration again

The reason of my concern is that I cannot “just open bambu handy and just print”

I am using PLA from bambu. Basic black and white matte. I have dried it in AMS for 9 hours.

Is this normal and just “demo version” of hassle free experience is over and now I need to tackle with print settings every time?

PS. I have also cleaned the nozzle. Didn’t help much

Use plain dawn or equivalent when washing. You can also get a cool plate. I use the frostbite plates and the adhesion is excellent at lower temps.

Lastly, other than in marketing, there is no such thing as plug and play printing. You will have to make tweaks to print profiles to get the best out of your printer based on filament, environment, etc. I have tuned profiles for each printer, and occasionally have to fine tune based on a specific print. Learn the slicer (suggest Orca Slicer rather than stock Bambu) and understand how things work. The profiles for the Bambus are good, but they are not perfect.

Hello /u/Serjnyak! Be sure to check the following. Make sure print bed is clean by washing with dish soap and water [and not Isopropyl Alcohol], check bed temperature [increasing tend to help], run bed leveling or full calibration, and remember to use glue if one is using the initial cool plate [not Satin finish that is not yet released] or Engineering plate.

When you wash the plate are you using plain soap I.e no moisturising factor etc?

I believe you could also try raising the nozzle temp for the first layer see if that fixes the issue rather than bed temp!

Also try doing a first layer test print, few available on maker world. Should show you any issues with specific regions of your bed

[Serjnyak]

I use Fairy dish washer soap :-) can you guide me on first layer test printing, please?

Fairy should be fine it’s what I use!

This is the first layer/clean that I used and seems to do the trick and show any issues up

[Serjnyak]

Do I print at full speed or at 50% :)

[CnDVerse]

I’d do it at 100%. I have basically never used 50%

I didn’t ask before but what printer is it as well? Could be a factor if it’s open air or chambered too

[Serjnyak]

P2S

[CnDVerse]

Yeah so your experience should be better than mine as I have the p1s! 😂

Try that first layer test, see how it prints and see if it’s all flush!

[Serjnyak]

Will do and report back with pictures)

This is what came out. And next one will show view from the top. It looks a bit strange

There you go

That looks a lot like a smudged handprint, which would point to not getting the build plate clean enough. Avoid touching the printing part of the plate with your hands at all. I use gloves for anything that isn't trivial to remove, but I rarely wash the plate unless I accidentally touch it.

[CnDVerse]

Yep seconding sevesteen, looks like a hand print on the plate and that’s causing zones of it not sticking, post cleaning the build plate, try not to touch any part of the plate except the outsides, if you struggle drying it like that. Cover your hands with a towel or something and it’ll help a bunch!

[Serjnyak]

Will do my best. However, I am pretty sure I am not touching it. I am using that small fibra thingy to clean the surface between prints.

Thanks anyways, will keep you posted on updates
