ABS does not stick to glass for me.Quote
For ABS, you can use the Red PCB @120C with bare glass, at any speed.
PLA does not auto release from glass for me.Quote
The ABS extrusion temperature should be around 250C. When the glass cools, the part will already be free. Same for PLA on bare glass.

One more thing. I use Pyrex Glass AKA Boro-Silicate Glass, so your results might varry with other types.

The first layer needs to be printed quite thin. less than 0.3mm, and go slow. At least half speed.

I've printed black PLA from Ultimachine succesfully on heated glass with my bed set around 70C.

I used to print the first layer at the same height as the layer thickness, 0.3 and 0,4 mm, on heated bed between 10-20 mm/s and it worked fine for me.

How do I get rid of the gaps, increase the object first layer infill flow rate?Quote
Bruce
It does however highlight gaps.... which shouldn't be there.
This is the first I have heard of this. Where is the goldilocks zone for the start nozzle height? How can I tell it's at just the right height without a specialized measurement device?Quote

I needed to be able to adjust it very small amounts to get the z-height just right to get a nice first layer that wasn't too hard to peel off, but still stuck.

Just called Michaels and they said my glass is tempered. cubevertex_export.gcode.zip is the gcode used to print the piece in the previous image. Had to zip it to bring it down under the allowed max size.

However, the toughened glass surface is not as hard as annealed glass and is therefore somewhat more susceptible to scratching. To prevent this, toughened glass manufacturers may apply various coatings and/or laminates[which?] to the surface of the glass.[[/quote]

BTW, Bruce, that unidentifiable "whitish thing" is probably from these guys
