# Cambios y comprobaciones en nuestro Marlin

Como hemos comentado es muy importante la configuración de SERIAL y BAUDIOS en Marlin (configuration.h), os ponemos como ejemplo algunas configuraciones para placas SKR.

## Configuración SERIAL placas SKR

**SKR 1.3**\
\#define SERIAL\_PORT 0\
\#define SERIAL\_PORT\_2 -1\
\
**SKR 1.4**\
\#define SERIAL\_PORT -1\
\#define SERIAL\_PORT\_2 0\
\
**SKR PRO 1.1**\
\#define SERIAL\_PORT -1\
\#define SERIAL\_PORT\_2 1\
\
**SKR MINI E3 V1.2**\
\#define SERIAL\_PORT 2\
\#define SERIAL\_PORT\_2 -1\
\
**SKR E3 DIP**\
\#define SERIAL\_PORT 2\
\#define SERIAL\_PORT\_2 -1

## Configuración BAUDRATE

En cuanto BAUDRATE podeis elegir entre estos que son los que suelen dar mejor resultado:\
\#define BAUDRATE 115200\
O\
\#define BAUDRATE 225000

## **También es aconsejable activar las siguientes funciones en Marlin:**

```
#define EMERGENCY_PARSER // Permite capturar acciones especiales
#define HOST_ACTION_COMMANDS // Habilita gestión de acciones desde el host
#define HOST_PROMPT_SUPPORT // Permite contestar acciones desde el host
```
