Someone commented on one of my designs saying “I tried this multiple times and had issues both times” and when I I asked if the had used supports they responded “how can I use support”. I swear to god man most of the people on makerworld must be kids who bought an a1 mini and have never used a 3d printer before that

Need a way to add an “IQ Captcha”, where they have to answer a couple of common sense questions to unlock the download/print ability

maybe just a " 1+1=? " will help ,lol

Thing is, for the most part those 1 star reviews don’t actually matter, if 100 people are rating it 5 starts and 1 is rating it 1 star the average won’t matter as it won’t drop below 4
Lol. No. If I review your print profile and give it a lower rating because of bed adhesion, it is because it is 100% absolutely, beyond any doubt,a flaw in the print profile.
I always, every single time, clean my build plate with 90% ISO. All of my filament is stored in dry boxes at 20% humidity. New filament is left in a heated dryer overnight. If I encounter any bed adhesion or first layer issues I switch to a new clean plate, if I still have issues I switch from a heated smooth plate to heated textured plate just to see if that fixes it (unlikely). If I’m still having issues I use glue (even though there should be no need with either PLA or PETG).
If I go through all that and there are still issues I can guarantee that the issue is in the print profile. Thankfully I now have enough experience and knowledge that I will figure out the issue, fix test and suggest the now working fixes to the original poster/creator of the profile but at that point I know with 100% certainty that the issue is with the profile and not me or my hardware. And these days, it always ends up being the profile.

there’s lots of things can effect the first layer , not just clean plate or dry filament, if you are the only one couldn’t get it print out, you still think that’s a print profile issue ?

Yes, and the majority of them are under the age of 13, which is prohibited in the Terms of Service. Not only that, but it’s prohibited for good reason: MakerWorld collects data on their users, and collecting data on individuals under the age of 13 violates COPPA in the US. @MakerWorld, just some friendly advice: Don’t get yourselves sued. Require some sort of age verification or do something about all <13 year olds on the platform.

alcohol does not properly clean plates hot water and dawn dish soap or similar is the way to go, Dawn is made to remove grease and oils thats why they use it on animals in oil spills… Alcohol can just smear the oils/grease. Its ok for minor touch ups between cleanings but not the proper way to clean the plate

This really depends on the plate.
I don’t disagree that soap and water is the best cleaning method…
But I clean my textured PEI plate with 70% IPA between prints and only have to clean with soap and water every few months and have very little adhesion issues.
In fact I have bad adhesion issues when I clean with soap and water only and not follow it up with a swipe of IPA before printing.
When using the holographic pattern plates and PETG, I have to clean with soap and water everytime to get it to stick.

microfiber cloth is not necessary and probably leaves lint or residue… i have used simple paper towels to wash and dry my build plates for 10 years now, even with my 500 x 500mm glass bed on my cr10 s5 I rarely have adhesion issues and those are usually my fault… ie i carelessly rubbed my hand or arm on the plate leaving body oils
If you have calibrated your filament profiles (which is the entire reason I use orca) are using a clean plate and dry filament and still have a first layer defect or even later layer defects the odds are it’s the print profile. If the machine can print anything else without issues, it’s absolutely, without any doubt, the print profile.
This is pure misinformation . 70% and up Alcohol will be just as good, if not better at removing oils and grease than dawn. Alcohol is a solvent, dawn is only a surfactant. To take that a step further alcohol will even dissolve residual pla whereas Dawn will not. So you will not be getting your plates clean if you only use Dawn and do not use alcohol while printing with pla
With that said, scrubbing is necessary either way

Exactly, and that’s why you need to use Dawn. When you dissolve something into a solvent and then evaporate the solvent away, whatever was dissolved into it is left behind right there on the surface it started on. A surfactant releases the bonds that a material has to a surface and allows the material to slide off the surface along with the surfactant when it is rinsed away.
Since people who use alcohol to clean their plates don’t rinse that alcohol away, but rather let it evaporate, the very thing they were trying to get off the plate is still left behind.
Just Google what happens to the matter that is dissolved into a solvent when that solvent evaporates and you’ll get all the good details. Or do your own science experiment and dissolve some salt or sugar into some water and then evaporate the water and see what you have left - yep, the original salt or sugar. Then dissolve another container of salt or sugar and use a surfactant and wash the dish out and let it dry and see what you have left - yep, nothing.

Isn’t it the case that such a pro would never have to rate ‘adhesion issues’ because they would discover it when looking at the print in the slicer before they print it?
Furthermore, that pro would just try another plate type?
Asking for a friend. He is confused.
in some cases the design of a model do effect the adhesion , most likely a small surface contact with build plate with a large model, or model isn’t balanced well make A1 or mini having hard time to print it
but when I’m having adhesion issues , I’ll check my build plate and filament first, I got more then 10 plates on hand, some just couldn’t handle PETG anymore
There are some less obvious things that can lead to bed adhesion issues. I have chased my tail for hours before only to find I had a partially clogged nozzle that was only partially disrupting the flow of the filament, thus screwing up everything. It drove me nuts.
Dry filament, the other one people do often point to, isn’t always the most obvious either. A lot of filament dryers out there don’t actually work and they can be misleading. Even the prints with the humidity sensors on this website don’t give you an accurate reading, so people can be running wet filament with the impression it’s dry and have no idea.
yeah, I was printing like that for years and have no idea why my filament in filament 8 hours and someone still telling me “dry your filament”
till I start using food dehydrator
different world
Yeah since 2012 when I got my first 2 Robo 3d’s with glass beds I have been using dawn dish soap and hot water on every printer since(mostly glass beds). Never had adhesion issues. Even with all my bambus probably only 5 adhesion issues that again were my fault for touching plate accidentally(these were the only times I used alcohol to spot clean and it was 91% or above)… but dont let my 12 years of successful printing derail you from giving your poor advice and misinformation to others…
Look what AI has to say, strange almost word for word what I wrote…
