Hoping someone may have some advice. I am experiencing many inconsistencies when printing and wondering if the aftermarket textured plate I got on Amazon has anything to do with it (I have seen a few influences mention that it was slightly thinner) - I ordered an official Bambu plate - and will try it out.
So in short - printing with Prusa MK3s - textured plate - perfect every time - plate cools - object comes off perfectly. With Bambu - when printing PolyTerra PLA it is on there for good - so good that when I peel it off - it leaves unbalanced whiteish textured marks on the first layer. I have calibrated this thing multiple times - it does work, the prints look good usually - but I believe the Z is just a tad bit too low. Is there anyway to live adjust the Z - or tell the Z to be raised? I think it may be possible in the start g-code but have not explored that yet. To be honest - I am trying to use this printer for what it claims - that anyone and everyone can easily use it (which for the most part is sort of true) - I don’t want to mess with Orca Slicer (which crashed on me 3 times yesterday and left a bad taste in my mouth) - I want to use BBS and adjust as many settings out of the box to dial it in, I did a manual calibration Flow Dynamics and Rate - all looks good. I just want some consistency when printing. I disabled LiDAR with the textured plate (which I assume is the Flow Calibration tick box when printing) - does not make a difference. I want to love this printer. I see influencers rave about it and the AMS has been working as expected - and the print quality has amazing - BUT I am frustrated with the fact that there are just some many inconsistencies either the print adheres or does not - different times when I keep doing the same thing without any changes. If I use the cool plate (and yes all my setting are correctly adjusted) - trying to get the prints off as well has been difficult. Any advice is greatly appreciated - thanks for looking.
I am printing Polyterra PLA with the recommended profile
I use aqua net hairspray on the engineering plate, might give that a try.
Thank you - this sounds interesting - I am trying it now and will update. I left the Plate type as textured though - as the BBS seems to have tooooo much control on what I want to do.
Just for kicks, I wanted to see what happened - so I changed the plate type to Engineering, and adjusted my filament settings to change the bed and layer temps AND when I went to slice, BBS would not let me and displayed an error and refused to slice the model because the filament I selected was not the recommended filament for that plate. It did not even let me override it. As I use this machine more I am starting not to like the level of control imposed by Bambu. First with the cloud service - I overlooked that, then with no ability to adjust Z-offset on the machine (every other printer I know of has this settings), then no ability to retain settings and seemingly have to level the bed each time and then finally with the inconsistencies of my prints - not to mention if you have to submit a support ticket - you can’t unless you provide them with logs and your model?!? - I am not sending them the models I worked hours on so it can end up somewhere unknown - I have already submitted a number of first layer fails through the printer (when changing absolutely nothing after already having a successful print with the same settings) - again each day I am starting to like this printer less and less - I have (4) Prusa MK3s printers and from day 1 they have been nothing but amazing and easy to use - yes it took me some time to dial in - but I have not had nearly as many first layer fails in the 4 years I have had the MK3s. Sorry for ranting - but I need to vent and I know there are similar situations out there. However all the YouTube influencers who got this machine for free sing it’s praises. I am hoping to get this dialed in and I can go back on my words. Though - this printer promised to make things easier - perhaps - but i makes things annoying too. My print just started on the engineering plate after that absurd start up. It looks to be adhering - I will report back.
Update - PolyTerra PLA using Texture Bed settings (heated bed 65c) - BUT using the Engineering Plate side as suggested by @silver118822 worked perfectly. Once cooled the print popped right off as expected. Thank you - I will update as I continued to use this method.
After reading what you described it seems you have cascading issues causing prints to fail. I have had mainly issues because of my filament being too wet.
First, get your build plate clean. Meaning wash with hot water and soap, after that rinse with very high alcohol.
Make sure your filament is dried properly. (TH <20%) There is a wiki page with recommendations for specific filaments
After drying do a flow calibration on cool plate and save this profile.
This way you can skip the flow calibration profile and use it for the textured plate.
On a textured pei plate I don’t use any adhesive. (to prevent tall objects from falling over you should consider using a proper brim)
In one of my failing prints I noticed when looking at the first layer it had a gap in the model. So effectively it was trying a long bridge on layer 2. This print needed a raft.
Glad to read you got better results with the engineering plate!
If anyone stumbles across this - my issue WAS the Amazon Knockoff version of the Bambu textured PEI plate. I bought an official plate and printed the same print that would always get stuck - I did it 3 times, same exact settings as when using the knockoff and each time after the bed cooled it came off easily as expected, with very little force, bending etc. so I answered my own question - there seems to be a difference - not only in thickness but possibly in the materials used to create it. Thanks to all who have provided suggestions. I learned a lot from you all and greatly appreciate your input. Stay well

Glad I could help - Luckily I was still within the 30 day return window. And since it had free returns I was able to get my money back for the aftermarket plate. Now that doesn’t technically mean that others couldn’t get it to work the way they needed it to. Perhaps by adjusting machine start G code or other calibration settings but that is not something I wanted to do I just wanted it to work out of the box the way it was supposed to. I will report back if I notice anything odd.
