Loctite for bed adhesion...
I can't get my Prusament, Orange. PETG, large, tall, thin print to not warp and stay on the bed no matter what I do. I have resorted to dabbing loctite to connect the brim to the part... Any tips are appreciated... z-axis is good, every surface, various fan speeds and bottom layer width.. Looking for that special something...

Prusament Orange PETG is usually the easiest PETG to print with. Here's my check list for warping:
Assuming (and this is a key assumption!) Live Z is well calibrated AND the steel sheet is squeaky clean (using hot water and fragrant-free dish washing soap), here are a few approaches that have worked for me:
- Slow down print speed.
- Add Mickey Mouse ears to the corners. You can add a cylindrical part in PrusaSlicer, maybe 10mm diameter, change height to single layer height, then place the part at the corner. Repeat for each corner.
- Add a brim around the model, 5 mm or more. Wider or 2 -layer high brims may be needed but may not work with the size of the model or may require being added in your CAD software.
- Use Layerneer Bed Weld ( https://www.amazon.com/Printer-Adhesive-Layerneer-Original-Filament/dp/B079984GV5/ ). You only need a thin layer.
- If you have design control over your part and it's possible considering the intended use, you can try to round the edges and/or add holes to the base of the model.
- Combination of above. Usually, brim/ears does the job, or some Layerneer if needed, but large, rectangular objects can be a challenge.

+1 - what @fuchsr said.
For some models I will reduce first layer print speed to 50% or less than default.
Raising bed temps by 5 degrees after the first layer may also help.
Cheers

Please, don't use ever again loctite near a printing plate. If the glue contacts the bed, it will damage irreversibly the PEI surface.

This is great stuff. Especially since all you can find is "your z is off" or "your bed is dirty". I've messed with those a ton. I know this is supposed to be the easiest petg to print with is why its o frustrating. I think because of the nature of the part. Any ways. Got a decent print going right now. I lowered the fans, used a brim and some magigo glue. So far so good. Getting some stringing...I think because of lower fan limits but totally worth it. Thanks for the thoughtful response!

Reducing first layer speed helped a ton!

I would go so far as to say not to have it or use it on the same work surface as your printer, under any circumstances. I learned this one the hard way... An unseen drop of superglue had fallen on top of my work table and not cured. Then when I set the sheet down on what I thought was a clean table, the drop of superglue basically wrecked one side of it. Don't do that.... I also now use an empty cardboard filament spool to set the sheet on when I remove it from the printer, rather than setting it directly on the table.
