For the record, the part you circled is actually reflected light, not poor adhesion, even though I agree that in the photo it looks like poor adhesion. I suppose I should have removed the build plate and photographed it outside of the H2D, but I didn’t.
As a point of comparison, consider this picture, which Bambulab refers to as “High Quality First Layer”:
Well, that’s about all I can say without beating an already dead horse. I thought others might chime in to confirm what I’m saying, but either they’re silent for no particular reason or else there simply are no others who are yet in a position to confirm.
Still waiting for my printer to arrive. Was scheduled yesterday, but has shifted already to coming Tuesday. Not to account of Bambulabs, but the transporter DB Schenker in this case.
Looking forward to that! I was starting to feel like Sisyphus. Maybe you can help by bringing your own perspective and/or way of explaining it, based on your own direct experience of it.
I don’t blame people for being skeptical, as right now I’m just a data point of one. If the shoe were on the other foot, I would probably be the same. If there were a second person reporting the same or similar, I think it would be far more than twice as persuasive.
I’m on beta 01.01.02.00 and don’t have any adhesion issue. Still reading your posts, I decided to do a first layer test to see what the result will be. To my dismay I experienced the same as what you are showing, some less than perfect adhesion mainly on the right bottom area…
You’ll notice I use a smooth PEI plate because that’s all I use, on my H2D as well as on my P1S. I don’t like the textured surface of the textured PEI plate and I hate cleaning with soap and water, I use IPA on my smooth plate as there are no recesses that can hold dirt and the more I print with it the more I clean it and the better it gets, this my preferred plate by far.
I think it was mentionned before but I had a look at the wiki which says this:
Use a screwdriver or Allen key to loosen the black side lock screw at the bottom front of the heatbed (about 1 turn). This screw is mainly used to increase the rigidity of the heatbed during transportation, but over-tightening may cause local lowness.
Re-run calibration and verify first-layer quality.
When I did that, I’ve heard a slight “clunk” like if some tension was released on the bed. I then ran cold and hot bed calibration, including the vibration calibration and reprinted my first layer tests. Note that this is all done at default settings for everything, filament, process, 0.20 standard default profile. Left nozzle is on light brown PLA Matte, right on white PLA basic.
The results exceeded my expectations, my first layer tests were PERFECT! See below:
Do you have any photos of that? I think some people just don’t believe, and it would be a good contrast with the improvement photos you show, if people could see the starting
Anyhow, thank you for your very nice write-up. You were the author of the prior post that I had marked as the thread “solution” when you posted about how the beta improved things. Now I’m updating the thread “solution” to be your most recent post, as it seems even like a good update to the prior one. However, in conclusion, people should realize that there may be more than one possible solution, depending, and there are at least a few different ones that have been posted to this thread, so look for the best fit or try them all. So, my message to the community at large: hopefully one or more will work for you!
I took this shot in the garage (so the sheet itself is shaded from the front) with lots of real daylight behind it.
Here are the shots while still on the build plate. And this time, to guarantee no reflections are causing you to think it lacks adhesion, I took it out of the H2D and photographed it on a cloudy day (diffuse light) and from multiple angles;
By the way, the build plate just happes to be a “cheap” $40 build plate I bought off of amazon. I didn’t have much hope for it when I placed the order, but as this print demonstrates, it works just fine.
Oh, and by the way, this was printed at 0.2mm layer height.
So, when certain nameless anonymous people materialize on this thread out of nowhere and start blathering about how great their prints all are without any tuning at all, in a whole range of different filaments, I say, great: Show us the photos, or it didn’t happen. It’s just too easy to be a blowhard and not back it up with anything.
