Did that once with some other instructions, but I will certainly try it again with this. Thanks!
Yes! That walk-through was fantastic. I had some significant errors in the flatness. This has been corrected, and I was finally able to begin printing. I still have some fine-tuning, evidently, as each pass in the first layer that was laid down was pulling up on the edges as the extruder reversed direction. I thought, perhaps, I came out of calibration, but my four points all seemed spot on when I tested. The search continues, but I’m excited that success feels near!
