[FluidNC Issue#1451] Problem: controller crashes after running-code

Wiki Search Terms

So when I’ve finished running g-code more often than not the controller crashes the serial interface and I can move the machine in some directions but not all, the positioning does not update on the g-code sender which is open builds. I’ve tried several gcode files and I get the same issue

I get no errors on the console and I need to connect via webui and reboot the controller several times.
It seems that the Webui works fine, I can home and move the machine.

Whilst in this state the controller can receive data from PC via USB as I can get it to move back to it’s zero but none of the co-ordinates update. It looks like serial comms is dying in one direction. I have tried different computers and USB cables no change.

If I disconnect the USB and try reconnect in openbuilds without reboot and reconnect I get the following errors that can only be resolved with several reboots. as you can see the job completes with no errors, but there is no further information from the ESP32 controller.
