The First Layer of Supports Is dragging/not sticking

I am trying to print a fairly small and simple table spinner type-thing. (The thing from Inception). I may have overdone the supports, but whenever the first layer of the supports prints it either curves up on the edges or completely fails and does not stick.

I have tried every type of factory reset and calibration there is. I've tightened all the belts and washed the bed with dish soap once in a while and isopropyl alcohol before every print. It seems like there is no surface adhesion at all

What material are you printing? If the bed is indeed clean, Live Z would be the first think I'd check and lower until I get adhesion.

Clean bed with dish soap. use hot water, use a lot of water, clean several times.

The print  a few squares, so you can adjust the z layer for every square different.

Then start to high with the z layer, then lower for every square.

I've adjusted live Z many times but I might try @peter-m-3's method to get it further adjusted

This is how I do it:

https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/

but I use a smaller square and change the Live Z 3 or 4 times per square, not just on the diagonal. 

Actually, I use the standard Prusa first layer calibration to just get to the point where my filament sticks, then I use jeffjordan's approach to fine tune it.

In the printer settings , set it to 7x7 calibration.

I had the print was going very well for a relatively long time.  Just now the nozzle randomly crashed into it. Any tips about that or is it just a weird mistake?
