I think I found the cause of the issue with the connected letters. For G0 moves the command is something like “G0 X10 Y20 F0” the ‘F0’ should be an ‘S0’ so the command would be “G0 X10 Y20 S0”.
Any idea how I might do that?
Nevermind, that’s a different issue and I’ll start a different thread. This thread is about how for some reason Pronterface is required in order to connect LightBurn.
