Comment on (Troubleshooting) Does anyone have an elegoo giga?

My daily printer is a 350 mm^3 Voron 2.4. I print larger prints most of the time, if you dig through my post history you’ll find some examples.
Your issue isn’t bed adhesion, it’s warping. I’ve had large prints coil to the point of pulling my spring steel bed off the magnet pretty significantly. You can continue to try to fight this (clamp the bed down), but ultimately you’re unlikely to succeed until you get warping under control.
Big prints can be very warp prone. In terms of ease/low warpage, I would say TPU > PLA > PETG > ASA/ABS.
Out of the box, Vorons are enclosed. I leave the sides on, close the door, and pop/rotate the top panel 45° for airflow when I’m printing both PLA and PETG. This has resulted in warp free prints for both materials.
For ASA/ABS, I was not able to achieve warp free prints until I was able to hit chamber temps of 55-60 °C thanks to swapping ACM panels and adding some radiant insulation. I also have 4x bedfans to help heat my chamber. Two are normal bedfans and two are part of an under bed carbon filter.
So questions:
- Are you running an enclosure?
- Do you know what chamber temps you’re able to achieve?

There’s no enclosure currently. It sounds like this is likely the culprit. It’s currently in a garage that isn’t very temperature controlled atm.
I don’t know about enclosure temps, but it will bet from around 55-72 F depending on time on day right now.

With no enclosure I would be pretty confident warping due to low ambient temp is what’s causing your print failures. With the top popped my chamber is around 40 °C / 104 °F and I haven’t experienced any PETG warping. My printer lives in my basement, which occupies a similar temperature range as your garage. On my old unenclosed i3 clone I would run into warping on bigger PETG prints.
If you’re feeling ambitious you could try throwing a (big) cardboard box over the whole thing and see if that helps. A few bed fans for good measure could be enough. I wouldn’t treat this as a permanent solution, but it could help you troubleshoot.
