I've, after significant effort and many tries, gotten UBL up and running. I'm confused, however, about two things.
First, what am I supposed to put in the start g-code in my slicer? Previously it was G28 and G29, now I'm thinking it should be G28 and ...? G29 T seems like the ideal option, but using that seems to disable UBL (G29 W says it's inactive) and it's clearly not working. G29 A T seems to do what I'd like, but I end up with the print head 0.5+mm over the print bed as it's laying down the skirt. Which leads me to question 2...
How is babystepping supposed to work? If, while the skirt is printing, I enter babystepping mode (click encoder twice), I can bring the head down .5 to .6mm and get actual adhesion. Once the skirt is done, though, the head hops right back up to where it was to begin printing the part.
Clearly, there's something I must be missing...
