What happened?

Unable to connect FluidNC-M5Dial/RJ12 verison to 6XCNC Controller –
1. The yaml file that I use works fine with my CNC machine,
2. When I add the additional code at the end of the yaml file, this error message shows up in the fluidnc browser.
3. Additional code added to the end of the yaml file:
uart2:
txd_pin: gpio.25
rxd_pin: gpio.27
rtspin: NOPIN
ctspin: NOPIN
baud: 1000000
mode: 8N1

uart_channel1:
reportintervalms: 75
uart_num: 2
4. I have already updated the firmware to the latest on the M5Dial and the
5. See attached error messages, yaml file, and reference images.

Your indentation in the configuration is wrong, remove the spaces in the beginning here:

Thanks for you response – I’m not sure what you mean?

#3 – breiler 于 2025-08-17

Open your config file, go to the row that says uart2 and remove any spaces before the “uart2:”.

#4 – shenzhenadam 于 2025-08-17

You mean … so it looks like this?

#5 – breiler 于 2025-08-17

Yes, as described here:

#6 – bdring 于 2025-08-17

The startup messages tell you where the error is. It is ignoring uart2. The config file has it indented under pwm: and pwm does not have a uart item.

I updated the yaml and removed the spaces … the pendant now connects and can control the machine via pendant .. Many thanks for your help.

I checked the wiki. If you search for “ignored key”, you get this.
