Many hours of troubleshooting and trying to figure out why my Z-axis lead screws would be off almost a 1/2" from one side to the other after a print have been resolved. I followed the Lulzbot tape measure method of leveling by hand with the motors off. I measured with calipers from the bed base to the X-axis guide rods and no matter what I did or how clean my nozzle was it would go out even after a small print. After following this method I found my bed was out of level .6mm and got it dialed in to .09mm! This has FINALLY resolved my issue. Ive done 3 prints to perfection with 2 of them taking up almost the whole bed. My lead screws are still in sync and you could ice skate across my first layer its so smooth compared to what it used to be. No drag marks, great adhesion, and no split layers up the print. To make sure my nozzle is making proper contact I run the M420S0, G28, G29V4 test before each print. Thank you for this resolution!
