My habit is to power up the machine and let it home, and ‘hot’ unplug the Y, with a ‘hot’ plugin of my rotary… Use it almost weekly and have about 7 months of doing it that way.
It didn’t seem to make any difference when I power cycled it and had to hammer the ‘esc’ key. The hardware looked pretty tough, so I started and have been just doing ‘hot’ swaps.
You can ‘esc’ out of the boot or reset…
I don’t know of a way to enable it at the controller
There is an option in ‘edit → device settings’ for enabling the Z axes, but I don’t remember it showing up in the rotary menu…
I cringe whenever I power equipment up, that’s when it always fails.
