I recently aquired a Prusa Mk3s and I want to be able to monitor my prints from it.
Installed Octopi on Rapi Zero W, created the static IP address fine, hooked it up fine, however I can not connect to it in either serial ports /dev/ttyUSB0 /dev/ttyAMA0 . In fact I cant even see USB0 in the drop down section even though I type it in.
I only receive this error....ever....
Offline (Error: IOError: '[Errno 25] Inappropriate ioctl for device' @ comm.py:_readline:2605)
