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. -
@FreakOnLeash the SKR3EZ has no voltage monitoring so can use the native power loss function. You'd have to use the BTT UPS to run a pause instead
-
@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. -
@FreakOnLeash yes. Just create a trigger using M581 https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m581-configure-external-trigger
you also probably want to turn on segmentation using
M669 S1 T1to speed up the pause -
undefined dc42 moved this topic from General Discussion

@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. -
@FreakOnLeash I would say your M581 should be
M581 T1 P9 S0 R1
T1 because you want it to pause and that's what T1 is. And P9 as you've used J9 in your M950. -
@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)
