Ok this is a weird one but can someone tell me the exact dimensions of the build plate? I have like four sets of notes written down and they range from anywhere from 9x6" to 230x150, to 228x149, etc. I have seen QIDI quote different numbers on Amazon and eBay and the Flashforge Google group has instructions on setting up the machine in Octoprint and they have different numbers too. I know a few mm's don't mean much but I want to get it exactly correct.
