Configuring digital0 pins causes reboot loop about fluidnc HOT 7 CLOSED

Instead of using GPIO for your step dir and enable pin, have you tried to use the I2S equivalent pin? See example in 6_pack_external_huanyang.yaml in https://github.com/bdring/FluidNC/blob/aaf3a3afe7a31c6a7fb2bef009864e1534a14a12/example_configs/6_pack_external_huanyang.yaml. for example: X axis step_pin: gpio.0 use step_pin: I2SO.2 instead and so on for the remaining axis.
You can consult the 6-pack pdf here https://github.com/bdring/6-Pack_CNC_Controller/tree/main/versions.

The 6pack uses an i2s port expander to provide those pins, they aren't directly connected to the ESP, the 4 axis board I have uses direct (well, buffered) esp pin connections

Sorry for misguiding you, I'll pay more attention to the details next time around..

No problem, i was quite confused about that too until i discussed it with Bart yesterday on discord. FWIW it is mentioned in the documentation here

I can confirm the bug. The pin is not initialized properly in the firmware. There is the discord thread for it and I added it to our bug list.

PR #135 fixes the problem for me. This will be included in the next release.

Should be fixed in current release
