Flashforge Finder

Has anyone with a Flashforge Finder bought one of these heated bed upgrades? I was wondering if it will help with warping.

Hey Finder users!
I got some problems with the bed leveling and nozzle height.
So I created this guide to help others with my experiences.

Hope you like it!
