I got the new Flex Bed and I have installed it. My original Z-Offset was -1.26 mm. The instructions to install the new Flex Bed say to add at least 1.5 mm to your current offset and tune from there. I adjusted the Z-Offset to 0.24 mm and tried a test print. The nozzle gouged the hell out of my new flex board. I added another 0.5 mm to the Z-Offset and it did the same thing. I added another 3 mm to the Z-Offset to see if it was even being used. It wasn’t, the nozzle gouged right into the new Flex Panel. I make changes to the Z-Offset, save them, re-home the printer, and then try my print. My start GCODE is below. Almost all of it comes from the Lulzbot version of Cura that ships with the printer, but I use Simplify3D. Any help on this would be greatly appreciated.
