Thank you jhertzberg
Actually, I positioned the model specifically like this because of the strength of the infill that, alined like this, would benefit the models necessary strength. But I should try it anyways.
Normally I have the brim turned on but I didn't think it would have any effect on the models warping because it's not even touching the model. Is the brim not just to get the flow going? And the model was to big for a Brim.
As you can see on the first photo, the blue tape came loose of the build platform but was still sticking to the model. So the model sticks well to the blue tape but the force of the warping is so big that it pulls the tape right of.
And if I enter "glue stick" in the search engine it gives no result, can you mention it one more time, please ;-)
jhertzberg has very good advice.
Why brim? Because sharp corners lift too easily. So much force is all on that one tiny spot at the corner of your part. Enough to lift it. Once the corner lifts the force is spread a little more but now there is leverage to pull more and twist it up. So a brim makes the corner round. Also the brim doesn't have any higher layers so it can concentrate on holding your part down. An ideal brim would get a little thicker where it meets the model.
Why isopropyl alcohol? It works! It increases the stickiness to the blue tape by 10X. Why? Because blue tape has a wax on it to allow it to be unwound. This wax needs to be removed with isopropyl alcohol. You can buy this at any store that sells bandages such as a pharmacy, supermarket, convenience store.
The next problem you may have is that the part sticks to the blue tape but the blue tape lifts from the bed. This is fixed with wider blue tape. I use 2 inch. Some people use 6 inch blue tape.
