    I’m very new to the Axidraw: attempting to preview my second ever plot via Inkscape, the extension crashes with the message below.

    The SVG file I’m trying to send was generated by custom software: it loads into Inkscape without any errors or warnings.

    I’m running Inkscape 1.2 on Arch Linux, with version 3.3.0 of the AxiDraw extensions.

    Error message:

    Traceback (most recent call last):

    Can you please share the SVG that is causing this?

    I’ve tried to post the SVG file, but my posts keep disappearing. I’ll try again later.

    I’d suggest following up with support by email or in our support Discord; attachments are much easier in either of those ways.

    OK — I’ve sent an email via the axidraw.com website.

    Windell sent me the fix for this. My plot had a background colour rectangle with no x,y coordinates: I changed

    <rect width=”100%” height=”100%” fill=”white”/>

    to

    <rect x=”0″ y=”0″ width=”100%” height=”100%” fill=”white”/>

    and the crash went away.
