Question can I use MKS PWC and UPS together?

[sima35]

I have a problem that both the PWC and the UPS are going to the same connector. I can't read your hub page

You cannot use both. Use only one

[proterian]

why not? just Use different port and configure in Marlin.

Yes, you can.
My configuration: Robin Nano v1.2 - PWC v3 - MKS UPS 24V - LVGL_UI
I am using the LVGL UI, I haven't tried it with other interfaces.

Basically you wire the PWC as shown in the instructions, the UPS module is not connected to the main board (just 24V and AC).

And we make following changes:

configuration_adv.h:
Enable: POWER_LOSS_RECOVERY
Enable: BACKUP_POWER_SUPPLY
Uncomment: #define POWER_LOSS_ZRAISE 20 // in mm

Marlin\src\pins\stm32f1\pins_MKS_ROBIN_NANO.h:
Change this part.
Uncomment #define MKSPWC, add a new definition UPS.
which controls if POWER_LOSS_PIN is declared in LVGL_UI interface.

//
// Misc. Functions
//
#if HAS_TFT_LVGL_UI
// LVGL
[…]

#define MKSPWC
#define UPS

#ifdef MKSPWC
#define SUICIDE_PIN PB2
#define SUICIDE_PIN_INVERTING false
#define KILL_PIN PA2
#define KILL_PIN_STATE true
#ifdef UPS
#define POWER_LOSS_PIN PA2
#endif
#endif

#define MT_DET_1_PIN PA4
#define MT_DET_2_PIN PE6
#define MT_DET_PIN_INVERTING false

#define WIFI_IO0_PIN PC13
#define WIFI_IO1_PIN PC7
#define WIFI_RESET_PIN PA5
#else
#ifdef UPS
#define POWER_LOSS_PIN PA2
#endif
#define PS_ON_PIN PB2
#define FIL_RUNOUT_PIN PA4
#define FIL_RUNOUT2_PIN PE6
#endif
