Hello 3D Hubs! I bought an Anycubic Kossel kit off of Amazon and built it. I’ve been trying to level it for weeks and have had no luck. My table is level, my build plate is level, my linear rails are all the same height, my z axis endstops are level, but I believe my print bed is scanning as shown here: http://boim.com/misc/CalDoc/distortLongRADIUS.svg

Please help! Thank you.
