I decided to pull the eggbot out of the cabinet after a couple of years, and got no movement when connecting it to Inkscape 0.92.5 (2060ec1f9f, 2020-04-08) and extensions downloaded yesterday from https://github.com/evil-mad/EggBot on Linux Mint 20 also freshly installed yesterday. The user account is a member of dialout group and has successfully written to USB-connected serial devices, e.g. updating Marlin firmware on a 3D printer.

Thought it might be due to old firmware, so shifted to a Windows 10 machine since I didn’t want to have to chase down those dependencies on Linux. Following the update to 2.5.4, on the Windows machine the Eggbot extensions work fine with Inkscape 1 and the same freshly downloaded extensions.

When reconnecting to the Linux machine, once again no movement from Eggbot Control and no reply when checking the firmware version – the “working” window flashes and disappears but no error message or other response that I can see.

AxiDraw control, however, will operate the servo and report the correct 2.6.5 firmware version. Checking firmwar version through WaterColortBot Control results in:

Traceback (most recent call last):
  File "wcb.py", line 37, in <module>
    import serial
ImportError: No module named serial

Dmesg reports the following when the USB is connected:

[234360.048903] usb 8-1: New USB device found, idVendor=04d8, idProduct=fd92, bcdDevice= 1.82

Any suggestions for me?
