Inkscape EggDuino Extension

This Inkscape extension helps you to use the EggDuino based EggBot from inside Inkscape.

Installation Linux and OSX

You have to put these two directories inside your ~/.config/inkscape folder.

curl -L https://github.com/section77/eggbot_extension/archive/1.1.tar.gz | tar -xz
mkdir -p ~/.config/inkscape
cp -r eggbot_extension-1.1/templates ~/.config/inkscape
cp -r eggbot_extension-1.1/extensions ~/.config/inkscape

Dependencies

Inkscape (obviously)
python
python-serial

On Debian or Debian-based distributions (Ubuntu, Mint) use apt-get/aptitude/apt, for example

sudo apt-get install inkscape python python-serial

Access Rights

On most GNU/Linux distributions you have to be member of the group dialout to use serial ports.

On Debian/Ubuntu/Mint you can add yourself to the dialout group with

sudo addgroup $USER dialout

You need to logout/logon or reboot to activate the change.

Troubleshooting

You aren't able to connect to your EggDuino? Try this:

Disconnect your board from your PC and execute

sudo dmesg -w

and plugin your Board. You should see something like

[ 4285.923992] usb 3-6: new full-speed USB device number 8 using xhci_hcd
[ 4286.065120] usb 3-6: New USB device found, idVendor=1a86, idProduct=7523
[ 4286.065123] usb 3-6: New USB device strings: Mfr=0, Product=2, SerialNumber=0
[ 4286.065124] usb 3-6: Product: USB2.0-Serial
[ 4286.065746] ch341 3-6:1.0: ch341-uart converter detected
[ 4286.066380] usb 3-6: ch341-uart converter now attached to ttyUSB0

The important pieces you can extract from the above: Your arduino clone (ch341-uart converter) is now available as /dev/ttyUSB0. You can now check the rights which are needed to access this device:

$ ls -la /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Mär  6 08:59 /dev/ttyUSB0

So you need to be root or are member of the group dialout. Are we?

$ groups
dialout cdrom floppy sudo audio dip video plugdev netdev lpadmin scanner bluetooth libvirt sbuild libvirt-qemu

Be sure the output of groups includes the group dialout as it does above.

Then start inkscape, select Erweiterungen/Extensions - EggBot - EggBot Control. On the Manual tab you can check the individual commands like pen up/down.

Installation Windows

You have to unpack the zip file from https://github.com/section77/eggbot_extension/archive/1.1.zip and copy the templates and extensions folders to the inkscape/share folder which is typically located at C:\programme\inkscape\share
