First off, thanks for all your work on this. 

I think I installed everything correctly. installed the bootloader from ISP, then flashed with vcode using the marlin configuration provided here, both the regular and ultimate. I can run the g28 and g29, without problem. I get some significant variances between the 9 spots checked in g29. When I go to print anything the z-axis it starts too high in the front, then catches near the middle and finally digs into the print bed about 3/4 of the way through. In my slicer, Cura, I see there are some commands that use the z-axis position, example: G1 X0.1 Y200.0 Z0.3 F1500.0 E15. I'm assuming the z-axis reference should not be there since the printer due to the auto mesh leveling. when I remove z-axis references the z-axis does not move from it's current position. no matter what it is. I've been working on this for 3 days now, I'm about to send the bltouch back and hope I can get the old way to work again. Anyone have any advice as to what I'm doing wrong or missing?
