[BUG] Homing fail causes print issues on start

[classicrocker883]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

• (I'm using UBL, w/ CR-Touch bed probe + ProUI on Ender-3V2 style printer)

When I start a print, and say homing fails (for the probe/Z axis), it does an odd behavior.
It seems to move with no speed/feedrate. but more importantly it prints in midair at the Z axis level where it failed to Home Z.

If there was a way to retry Homing the Z axis, and if it still fails, to abort the print.

Bug Timeline

No response

Expected behavior

After the Z axis fails to home/be trusted (w/ or w/o a probe), it should retry homing, and probably abort the print after so many tries.

Actual behavior

After say the probe fails to deploy, it still proceeds to continue the print, except way above the bed surface, and at a very slow speed.

Steps to Reproduce

1. Start a print.
2. Somehow cause the probe or endstop to fail for the Z axis.
