    Which version of Inkscape are you using, and which version of the EggBot extensions are you using?


    Thankyou for replying

    I’m using windows Pc/ Inkscape version 0.91 and Eggbot 250A

    All downloaded from

    I had no problem using eggbot pro until yesterday. suddenly it started to show error message yesterday

    Great– thanks!

    Let’s try upgrading you to a slightly newer version of the extensions, to see if that fixes it.

    Download this package:

    Unzip it and copy the entire contents of the “extensions” directory from that zip archive to your Inkscape extensions directory, overwriting the like-named files there.

    Your extensions directory is located at:
    C:\Program Files\Inkscape\share\extensions\

    Then, restart Inkscape, and see if you have good communication to the EggBot.


    thankyou! it works perfect now!

    Fantastic, and thank you for following up!
