I'm pretty new to printing PETG, and my Creality Ender 3 now has a glass print bed. I've done some research, and it looks like a pretty bad idea to try and print PETG on a pure glass surface for fear of the print pulling chinks of glass along with it.

So, I've looked into various bed adhesion options. I've already used blue tape, but I'll need to purchase some wide stuff, and in the meantime, I want to investigate using PVA-based glue stick. However, one question does come to mind: how can I set the bed-nozzle distance after applying the glue stick layer?

Do I even need to? Will the extruded plastic just crush it into the build plate without a problem, saving me the trouble of lowering the build plate? My normal method of sliding a paper sheet under the nozzle at Z = 0 mm would take the glue stick layer along with it if I tried that.
