The one thing to note is that I saw a photo somewhere else of someone using this glass plate clamped directly on top of the stock aluminum build plate. I have no idea how they managed that because I tried it and it was impossible because the platform became so thick that I couldn't screw down the leveling nuts far enough to clear the nozzle. Only after I removed the metal plate could I get the platform to clear the nozzle. While I've heard it can be done, I'm not printing directly on the glass, instead continuing to use blue painters tape. My main reason being that sometimes my models really stick hard to the platform and I have to use a putty knife to "pop" them off. I didn't want to scratch the bejeesus out of the glass plate right off the bat. Perhaps I'll give it a try without tape at some point.

You can print a spacer that sits at the rear of the build plate support that stops the z axis to enable you to use the glass bed on top of the stock bed. There are a few on Thingiverse to choose from. Just search flashforge glass bed shim and you should find one that you like. Note:I had to adjust the height of the shim to just higher (6.65mm) than my glass bed that came in at 6.55mm thick that gave me some fail safe room that i could then use the adjustment screws to level out. I happened to find some transfer tape that was the right thickness in my junk bin lol it had a added benefit of holding the shim in place as well. but you could design your own if needed. Good reason to never discard scraps for other products they might just come in handy I hope this helps
