That worked! Just had to send M997, can't believe it was that simple. Thank you so much! I would've been scratching my head for days.

I have been using Duet boards for a couple years now and I have run across this issue on a Duet 3 MB6HC with SBC RPI4 and cannot find anyone else having this issue. Everytime I try to run a print from the DWC it gives this "Error: M32: Cannot set file to print, because a file is already being printed" then changes status from idle to printing and doesn't do anything but stay at 0% progress. I was able to configure and move the machine around and I have printed with this mainboard and sbc with no problems before. Reformatting SD card, reloading firmware, and using different slicers yielded the same result. I am running firmware 3.3 with DWC 3.4. I have no idea what is happening here, please help! Update: I can run prints from the macros directory but this isn't ideal.
