Not working on Marlin 2.7.1.2 SKR1.4

[Ejay-3D]

Hi, I installed UPS 24V 1.0 module on a BIqu B1 that have a skr 1.4 board. The wiring is correctly done and the frimware instruction followed correctly as well . While printing, if I remove the power cable :

• The Z Does not Raise
• The machine shutdown after 1 seconds
• After resuming the print restart much more earlier than when it stopped, with a beautiful blob on the print due to the fact Z Didn't raise.

Conclusion With or without the module I don't see much difference, the only difference is that the print continues a bit more time ... than without ...

It might be due to the Pin used in the firmware : In configuration_adv.h I set define PLR_ENABLED_DEFAULT false define POWER_LOSS_PIN P1_00 define POWER_LOSS_STATE HIGH define POWER_LOSS_ZRAISE 10

As it is define like : in lpc1768/pins_BTT_SKR_V1_4.h

#ifndef POWER_LOSS_PIN #define POWER_LOSS_PIN P1_00 // PWRDET #endif

Is this correct ?

Any advices?

Is anyone from BTT looking a those Git issues ?

The clear thing is that on a SKR1.4 using MArling 2.7.1.2 , the resume gcode status is not saved therefore it's not possible to resume a print when printing from mother board.

On the Screeen ( since the screen is not aware of the UPS) It doesn't do what it should before shutdown then the module is unusefull as well .

Try adding M75 to your start gcode manually through your software. Also add M77 to end gcode.

Still the Same issue With The Biqu BX SKR 2.0 . The Z Doesn't Raise on power failure , but goes down of 10 after resuming ... Sad to see that Btt is not looking at the issue opened here ...
