It's still producing the same issue on the TineBee. I have tried even using the pins from UART2 just to make sure my IO were ok to use and it's...

Ah I think I have found the problem. uart->num for Serial 1 is overriding Serial 0 as the case is 1 off (same for others) switch(uart->num) { #ifdef UART0_PINS_REDEFINED case...

Is UART_RX_PIN/UART_TX_PIN for UART0 or UART1? Looking at the diagram, it should be for UART1  Uart0: IO1/IO3 Uart1: IO34/IO35 //default, or UART_RX_PIN UART_TX_PIN Uart2: UART2_RX_PIN/UART2_TX_PIN

II'm using IO35 as my auto squater Y axis as it's the same connector as the rest of the end stops. Even if Uart and Y2 limit are on the...
