Mac OSX 10.11.1 eggbot extension 2.6.3 problems with Inkscape 0.91

[wingnut59]

I had the problem where I had to disconnect the usb cable between each plot. I’m using Inkscape 0.91. I saw that upgrading the extension to version 2.6.3 was reported to fix the issue. what it did for me was make it worse, I cannot do anything with the egg-bot now. Whenever I try to issue a command, i get the following:

Traceback (most recent call last)

  File “eggbot.py”, line 1373, in <module>

    e.affect()

OSError: [Errno 2] No such file or directory: ‘/dev/cu.usbmodemfa14’

I’ve had my egg-bot for quite a while, has the red EiBot board from i think SparkFun. looking at the system Information, the EiBot reports:

EiBotBoard:

  Product ID: 0xfd92

  Vendor ID: 0x04d8  (Microchip Technology Inc.)

  Version: 1.82

  Speed: Up to 12 Mb/sec

  Manufacturer: SchmalzHaus

  Location ID: 0xfa130000 / 4

  Current Available (mA): 1000

  Current Required (mA): 100

  Extra Operating Current (mA): 0

I’ve tried uninstalling Inkscape and reinstalling with no luck.

Any help would be appreciated.

That’s the first report that we’ve had of 2.6.3 _not_ working. 

I do have one thing that you can try, which is rolling back to the earlier version of pyserial:

Download the older (2.5.0) version of the EggBot extensions, from here: 

https://github.com/evil-mad/EggBot/releases/download/v2.5.0/EggBot_extensions_v2.5.zip

Unzip that archive, and inside it, locate the “Serial” folder inside the Extensions folder. Then, copy over ONLY that serial folder to your current Inkscape extensions directory, replacing the entire folder. You should be able to test it immediately; you should not even need to restart Inkscape if you’re just replacing the serial folder.

Your Inkscape extensions directory is located at: /Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/ 

 You can get there by selecting from the menu bar in the finder: Go > Go to Folder… , and pasting that directory name there.

Works like a champ with the serial folder replaced by the 2.5.0 version

Thanks so much

Well… Awesome… and baffling? 

I’ll dig in a bit, and see if I can figure out what the issue is. I may follow up later in this thread with a new version for you to try.  It’s awfully difficult to debug issues that we can’t reproduce locally. :)
