Prints pulling up at corners

Ok for some reason fan for layer 2 was turned off. Weird. Fan is back.

I do have another question. In the "Support Structure Underspeed" in "other" is it the higher the number the more it slows the support print down or the opposite? I want to really slow the support printing down. I feel like my supports are getting knocked over bc it's going to fast, I've also made them 6mm big bc they 4 seemed very small and delicate. Does that make sense?

100% is full speed, 50% is half speed.

After all the changes the corners are still pulling up. I'll run the bed wizard now.

Maybe hard to see in the photo, but all four corners are are as badly warped.
But it seems like this isn't a bed leveling problem since all four corners of the model are pulling up right?

Maybe I'll try to the blue tape, I just don't like the idea of it ripping off in little pieces and having to reapply it so often.

Other than that, where do I go from here. Getting frustrated.

Did you ever read the "How To: Guide to Getting Started"? If you follow the steps in the guide, (and read the information in the second Troubleshooting section), you are going to understand what's happening, and you will then be able to fix it.

You've got a couple of things going on with your print: the Z-Offset issue, the adhesion problem, and you are printing PLA, which has some things that have to be done specific to that filament because it warps as it cools. All of that information is together in the Getting Started Guide, in a logical progression for what to check. Instead of you having to spend weeks asking questions from people who aren't there and can't see it to diagnose it, and getting conflicting answers, read the Guide. (All the way through once, then go back and start your re-setting and calibrations.)

I compiled it for beginners, so they wouldn't have to spend months asking questions, and getting more and more frustrated because they don't understand it yet.

Yes, it was a very helpful guide. I've read it multiple times. I have it printed and as a reference right next to printer. But it doesn't cover everything and still left me guessing on many things and stumbling around to different posts. The temperatures are still a guessing game, some settings aren't mentioned. Very good guide though, thanks for writing it.

I guess I'm giving up on glue & hairspray. I finally got a print that doesn't warp with blue tape. I also just ordered a zebra plate.

It seems like it was just a bed adhesion issue. At one point it may have been a bed leveling and zstop too, but I'm pretty sure those are fixed now. And if the print is sticking on tape, then I'm probably good to go right? The print looks good.

I really wanted to use the hairspray and or glue though. Could it just be a temperature issue? I'm in Colorado so higher altitude and less humidity, can that cause problems?

No idea.....but it might.

Always a voyage of discovery at first - some people swear by hairspray, others like gluestick, some swear by tape, and some print on bare glass. (The trick is to find what works for you and then you're good to go.

)

Ok thanks Jules!

your still way too far from the bed. you have no bed contact there. you can see between every extrusion line.

Yeah, it looked that way to me too, but then when he put the tape on the glass, it narrowed the gap. He says it's finally sticking in his last post. (Was going to wait to see if it still warps up on the tape.)

But you're so right....it's all about the gap. Before he put the tape on the glass, it was still too far out. (By about the thickness of the tape, guessing about 0.10 to 0.15 mm.)

If he starts using a Zebra plate, it's all going to need to be re-set anyway, so i figured, since he's got it working now, it should be good enough for a few days until the plate arrives.
