@1kemanciii you need a pwm pin , so PA1 & PA2 can be use as PWM , you have to change pin assignment if you use XMAX or YMAX pinout. ` #define X_MAX_PIN PA2 #define Y_MAX_PIN PA1 #define Z_MAX_PIN PC3 //#define X_MIN_PIN PC2 //#define Y_MIN_PIN PC1 //#define Z_MIN_PIN PC0

`

to

` #define X_MAX_PIN PC2

#define Y_MAX_PIN PC1 #define Z_MAX_PIN PC0 //#define X_MIN_PIN PC2 //#define Y_MIN_PIN PC1 //#define Z_MIN_PIN PC0 `

And defin bltouch pin to PA1 or PA2

not possible if you also use XMIN connectors

Hii, if you are still interested or for everyone else having troubles with BLTouch configuration on SKR MINI here are my mods: I've added this: -In pins_BIGTREE_SKR_MINI_V1_1.h: (the pin are located on EXP2 connector) //Servo Pin #define SERVO0_PIN PB8 // Z Probe must be this pin #define Z_MIN_PROBE_PIN PB9 -In configuration.h: #define BLTOUCH #define AUTO_BED_LEVELING_BILINEAR #define Z_SAFE_HOMING Please note that pins for endstop are not suitable because they have an RC filter on it!!!

Hi bro, what is the reuslt of this mod? I got and very poor repeatibility problems with this board, as mention in https://github.com/bigtreetech/BIGTREETECH-SKR-MINI-V1.1/issues/31

Can't understand very well what's your question. I've defined that pins in order to do not use the gpio wich has RC filter on it. Haven't tested repeatibility.

Hello, i have question (pins_BT_SKR_mini_V1_1.h( // BLtouch #define SERVO0_PIN PA1
// Limit Switches #define Y_MIN_PIN PC1 #define X_MIN_PIN PC2 #define Z_MIN_PIN PC0 //#define Y_MAX_PIN PA1 //#define X_MAX_PIN PA2 #define Z_MAX_PIN PC3

(configuration.h) #define Z_MIN_PROBE_PIN PC0 // Pin 32 is the RAMPS default

its ok ? or im wrong

With this MOD in Marlin... where must be pluged in the Cables?
