I don't understand, did you try to attach a screenshot? If so you need to add it on the GitHub webpage. |

Looks like you are missing the permissions to access your controller. Open a terminal and try this to add your user account "pi" to the group "dialout" which should allow you to connect to the serial device. Restart your PI after this. |

Thanks Joancim
Im a novice at using Pi/ Linux.
I tried what you suggested substituting my Pi user name for Pi in "sudo usermod -a -G dialout pi (is that correct?)
But still got the same error message.
I have gSender installed on the same Pi device and it connects to my CNC on the same USB port without any issues.
if I had the above syntax correct should I try anything else?
Cheers
Bob

The port I need UGS to access is /dev/ttyUSB0

ALL SORTED PROBLEM SOLVED.
Turns out I was over thinking it.
All I needed to do was prior to connecting select ttyUSB0 in the port setting then connect.
I feel a bit foolish for wasting your time on this.
there is one minor issue remaining
When UGS loads its displaying the gSender icon. Is it possible for me to change this?
Cheers
BOB

From all the searching I've done it appears that at this time UGS and Raspberry Pi 4 are incompatiable. Is this likly to be resolved in the near future or is it in the to hard basket for now
