Hello Luiz,

I would like to request a new feature, on the web interface add a link to shutdown the Raspberry Pi... sudo shutdown 0.
I have your project running on my Elegoo Saturn and Mars 2 pro's. The only real issue I'm having is the constant:
The printer returned an unexpected response: ok N:0\r\n
The printer returned an unexpected response: ok N:0
The printer returned an unexpected response: ''

Set up a Gofundme or or a donate link.. I'm sure some will contribute.

Thanks,
Nathan C.
