POWER_LOSS_RECOVERY do not work properly

Hello,


I pause the print then turn off and wait a while and turn it on again however there is not resume print.
I defined POWER_LOSS_RECOVERY but it does not work and I am sure power loss recovery is enabled while printing

how can I fix it?


my printer is ender 3 pro with skr mini v2 and bltouch

Thanks,

That controller has a POWER_LOSS_PIN on the motherboard.

ie In the pins files is this

//
// Power-loss Detection
//
#ifndef POWER_LOSS_PIN
#define POWER_LOSS_PIN PC12 // Power Loss Detection: PWR-DET
#endif


You need to change this in Configuration_adv.h from

//#define POWER_LOSS_PIN 44 // Pin to detect power loss. Set to -1 to disable default pin on boards without module.

to

#define POWER_LOSS_PIN -1 // Pin to detect power loss. Set to -1 to disable default pin on boards without module.


Presuming your not using power loss detection boards..

I updated line to this

#define POWER_LOSS_RECOVERY
#if ENABLED(POWER_LOSS_RECOVERY)
#define PLR_ENABLED_DEFAULT true // Power Loss Recovery enabled by default. (Set with 'M413 Sn' & M500)
//#define BACKUP_POWER_SUPPLY // Backup power / UPS to move the steppers on power loss
//#define POWER_LOSS_ZRAISE 2 // (mm) Z axis raise on resume (on power loss with UPS)
#define POWER_LOSS_PIN -1 // Pin to detect power loss. Set to -1 to disable default pin on boards without module.

and tested but still it does not work.

I do not have power loss detection board.
