Hello,

I have been using the Flashforge Creator Pro for 3 months now without any issues until I decided to purchase a flexible glass plate kit from Proto -pasta. It adds a bit of thickness so I had to re-level the bed. Problem is that when I was turning the wingnuts two of the wingnuts got loose from the screw to the point where if I turn them I'm only turning the wingnuts and not the screw therefore turning them does not raise or lower the print bed. Maybe it's just my inexperience with leveling the bed. I had done it when I first got the printer but haven't had to since, but I can't seem to figure out how to level the bed now or fix the issue or why it's happening.

Also proto pasta didn't say anything about adding a shim... Just that it affects bed leveling because of the added thickness. Not sure if its necessary or if I could lower the bed enough. Here is a link to it:http://www.proto-pasta.com/collectio...ant=3907441348

The sheet is 1.6mm thick.
