I tried changing a few things in the configuration.h but now octoprint constantly puts out the following error:
write failed: [Errno 22] Invalid argument' @ comm.py:_do_send_without_checksum:3490
Updating the Marlin version did not help I do have a second device named /dev/ttyS0 under the serial port tab
I also tried reflashing the image onto the pi. If I just flash it it works, but as soon as I update the marlin code it gives me the error.
