nanoDLP

Hello, everybody

Here I have problems to control Wanhao D7 + through NanoDLP

Just starting to control printer up and down and than connection losses

"Serial port could not be activated no such file or directory"
I can't reconnect RAMPS and restart Raspberry PI3 and printer

I installed firmware and made all steps from video

Including:
1) installed firmware from manual 3d printer wiki info
2) installed img for rbp also from link above
3) UPDATED until stable version -- here may be a problem, version of nanodlp now is 1932
4) expanded filesystem

Another details:

Connection from RBP to PC through LAN (not through Wi-Fi)
