A3S V1 Air Prints from Z at Which Temperature is Set, Unless G28 (Home Extruder) is Added Manually

I was solving this with "baby-" but now have an automatic workaround. The nozzle doesn't go back down to the bed after raising the nozzle to wait for temperatures to be reached. I must set home after that by manually editing the gcode. That is the only way it will work (see below). If I enable mesh leveling after that, it fails too (commented in code below). Why does this happen?
The first part of the code (with the workaround) is below.
The "code" and "pre" tags show up fine if I click preview on the post, but not when I click on the article. I tried "code spoiler" but then the preview actually removed the code when I click preview (only showing links), and ignores newlines. I'm using "pre" inside of a spoiler for now. Here's a Pastebin link in case it still doesn't display correctly: https://pastebin.com/KEygJuwe

I will post more information after I try re-adding the
M420 S1 ; enable mesh bed leveling (Pinches, 2018)line (from https://jgaurorawiki.com/a5/mesh-bed-levelling-routine) after the existing G28 (home all axes).Howdy, Stranger!
