I really like the idea of Laserweb. I have a Raspberry pi3 based DIY system with a protoneer board. There does not seem to be support for an ARM based appimage so I eventually managed to install the sever manually but when run there were no com ports. Any info on how to get this running on the pi please?
I don’t recommend using the RX/TX pins of the RasPi to connect the Grbl shield, because this way the Arduino will not be reset on connection. Use an USB cable instead.
