    I upgraded to 2.8b and have reinstalled the latest UBW drivers. I am running Win7 64bit.

    After upgrading inkscape I am not getting the following message when I click on the apply button to try to do any function with the eggbot.

    The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension.Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml

    Technical details:
    No module named lxml

    Thanks for the help

    We are still not recommending 0.92 for various reasons. (We’d still generally advise to stick with 0.91 for the moment.)

    We have heard of this particular error three times in recent memory, and on Windows only. It appears to be due to a conflict on your system about where the python “home” directory is located. One workaround that we have seen work is to edit your environment variables, and remove the one called PythonHome.

    This guide shows you how to access and edit your environment variables in Windows 7:

    Thanks

    I installed .91 and I am back to where I was when I upgraded to .92. I can see the arduino uno in device manager – USB-SERIAL CH340 (COM3) but when I try to connect using the eggbot extension in inkscape I get “Failed to connect to EggBot. :(“

    Good; that resolves the LXML issue.

    As far as the rest goes, that’s not one used by either Arduino or EggBot, so you might be on your own.

    it is the arduino. it disappears when I unplug it and reappears when plugged back in. I have tried two different USB cables. I also tried a different uno and it came up the same. I am guessing this has to do with the ubw driver

    So far as I know, no actual Arduino ever used the CH340 — just some cheap knockoffs. In any case, this support forum is for EggBot, so I’m closing this topic.
