@jay_s_uk thanks for help, everithing now working!
I also added macros:
Power_loss_recovery.g
G1 H2 Z-5 F6000
M916
For some reason Z was raising for extra 5 mm before applying M916.
Maybe this macros not best solution but it work + easy access to recovery from browser)

@jay_s_uk added in end of config.g lines:
M669 S1 T1
M950 J9 C"pwrdet"
M581 T2 P0:1 S0 R1
and create trigger2.g. with just M25 in it.
In console trigger2.g working, when i type M582 T2 it paused print, but when power is off nothing happened.

@jay_s_uk any idea how to run pause from UPS?
I have BTT UPS. Connected him like was shown in board manual

But still after cutting power printhead stops, drain power from ups and that's it.

Hi, i have SKR3EZ in standalone mode, 24V PSU from Ender3pro + BTT UPS 24V and can't set it up correctly.
I updated firmware to 3.4.5_102, did all settings like in https://docs.duet3d.com/en/User_manual/Tuning/Resume,
(M911 S21.0 R23.0 P"M913 X0 Y0 G91 M83 G1 Z3 E-5 F1000") but it doesn't work.
When power turns off it just stops in place. M911 didn't write resurrect.g.
When manually pausing a print it created resurrect.g.
Tried different voltage in M911, nothing helped.
