Prints are not in contact with the print bed
The bases of the printed items are not completely attached to the print bed.

What type of filament are you using?
Check the first layer calibration.
If you are using ASA or ABS, try an enclosure and a full height draft shield. Print Settings | Skirt and Brim | Skirt | Draft Shield.
That will result in less warping and pulling off the bed.

RE: Prints are not in contact with the print bed
Filament is Hatchbox ABS (I do have Prusament ABS also). This may be a stupid question but when you are talking about an enclosure could it be something so simple as a large cardboard box?
RE: Prints are not in contact with the print bed
Just google for 3D print warping and you'll see thousands of comments and suggestions. My standard copy-and-paste:
It's common for large box-shaped/rectangular objects to warp. Assuming Live Z is well calibrated and the steel sheet is clean (using hot water and fragrant-free dish washing soap), here are a few approaches that have worked for me (copied/pasted from previous posts):
- Slow down print speed.
- Add Mickey Mouse ears to the corners. There's a "helper disk" in PrusaSlicer's Add Part library but I prefer to simply add a cylindrical, 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/ ), Magigoo, etc. 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. Also, drafts can encourage warping, so printing in an enclosure (with doors open for PLA) may help.

A large cardboard box would do!

Thank you for the suggestions. Will try on the next run.
RE:
The only issue with a cardboard box is if the print comes completely off the bed and you get a spaghetti monster (google that) you won't see it. An Ikea Lack table and 4 pieces of plexiglass works great. There are threads on enclosures.
ABS is particularly sensitive to warping and an enclosure is a major help. I fear that if you continue without one you will continue to have problems. ABS is also very smelly and the fumes are bad for you. I hope this is in a ventilated location.

A lack enclosure would be ideal, but to solve your not seeing it issue just cut a hole in the box to view thru and just reattach the piece as a flap with some tape. Then you can keep an eye on it.
Good luck.

Do yourself a favor and use ASA instead of ABS. Same properties but UV resistant, smells less, and prints much more nicely.

+1 to that. My ASA prints come out pretty well using stuff on the list from @fuchsr, skirt and brim, and the enclosure.
On the box enclosure, just cut a hole and tape a piece of plastic wrap over it to see what is happening.
