EDIT: Ah, I found what I was looking for: linuxcnc.org/docs/html/user/user-concepts.html#_path_following
I got my ATC working tonight, but one thing I'm seeing is that the following code doesn't move first in Z and then in Y. It moves most of the way in Z, then starts moving in Y before the Z is complete. I think this is a mode, right? How do I get it to finish Z before Y?

G53 G1 F4000 Z #<_ini[atc]z_pocket> ; Move down in front of fork
G53 G1 F3000 Y #<_ini[atc]y_pocket> ; Move tool into fork

Placing a command that forces a synch between the g1 moves
will probably suffice.
Using a dummy read command (M66E0L0) is often convenient
with minimal side effects (it will update #5399).

You think that's better than G64?

As the description says, G64 Path Blending, there is an area with 2 axis moving. i would use G61 Exact Path Mode to execute one move after the other, or if you want keep the setting for G64 , a queue-buster M66 as recommended before
