 * Download my updated windows version of python from : https://www.dropbox.com/s/693n7m2fdq6160d/Python27.rar?dl=1
 * Navigate to C:\Program Files\Inkscape and rename the folder "python" to "python-old"

+* If you run the export plugin and you don't get a popup diagnostic log telling you which items were exported successfully then unfortunately you need to install Python manually as described below in option #2
 
 2) You can alternatively install python on your system, or use my precompiled version. To install python natively :
 * visit https://www.python.org/downloads/ and download python 2.7.9 and install it to C:\Python27\ . Select the option to add Python to your path during install.

+Sending the file to your laser
+------------------------------
+You can send the file to your laser by serial (USB cable) or SD memory card. 
+
+1) Via USB cable
+* Download repetier host and install it on your PC - http://www.repetier.com/download/
+* Open the software and set the port of your laser in the options. It will typically be COM7 - otherwise it's the same as what your programmed your Arduino on originally. The port speed should be set to 115200
+* Press the connect button, it will turn green.
+* Open your gcode file you created earlier and press the print button. Your laser will now burn your instruction set.
+* I have found the repetier host sometimes repeatedly fails unexpectedly when burning vector lines after a raster for no apparent reason. It will suddenly stop sending further instructions to the laser and the arduino needs to be power cycled.
+
+
+Alternatively you can use pronterface http://www.pronterface.com/index.html#download however pronterface has a bug which prevents it from correctly reading the raster data.
+At the moment if you want to use pronterface to burn rasters you must replace all instances of + and / in your raster data with the number 9. The GCode is just a text file, you can do a find and replace on these characters in your text editor.
+I have found that pronterface is 100% reliable for burning the vectors that repetier host has issue with.
+
+2) Via SD Memory card
+* Place the file onto your SD card
+* Insert it into your ramps SD card reader.
+* Select the file from the ramps LCD menu and print.
