pseudorandomnumber

Try defining the UART outside the "SiemensV20" block, as described in the wiki: http://wiki.fluidnc.com/en/config/config_spindles#:~:text=uart1%3A%20txd_pin%3A%20gpio.17%20rxd_pin%3A%20gpio.16%20rts_pin%3A%20gpio.4%20baud%3A%209600%20mode%3A%208e1%20siemensv20%3A%20uart_num%3A%201%20modbus_id%3A%201%20tool_num%3A%200%20speed_map%3A%200%3D0%25%2024000%3D100%25

Like so: ``` uart1: txd_pin: gpio.15 rxd_pin: gpio.16 rts_pin: gpio.14 baud: 9600 mode: 8E1 SiemensV20: uart_num: 1 debug: 0 modbus_id: 1 tool_num: 0 spinup_ms: 20000 spindown_ms: 20000 speed_map: 0=0% 1=12.5%...
