Here are two more things to check:
1. At the terminal, please list the output of:
ls -l /dev/ttyACM*
— just in case there is some other permissions error on your system.
2. Check to see if python can connect to the EBB directly:
At the terminal, try the following four commands, and let me know the output of numbers 2 & 3:
1. python
2. import serial
3. serial.Serial(‘/dev/ttyACM0’)
(if your EBB shows up at a different ACMx number, please use that instead)
4. quit()
If step 2 fails, move to the directory where your eggbot extensions are located (usually .config/inkscape/extensions/) and try again.
