In this instructable, I will attempt to guide you through the way to get the PolyPrinter fully functional on a Mac.
Step 1: Prerequisites
To check to see if you have Lua installed, open a terminal window and type the following:
You should be rewarded with the Lua prompt, which should look like the screenshot.
If you don't get a prompt like that, follow the install procedure for lua which can be found at: http://www.lua.org/
Step 2: Downloading the Files
Post Process file should be attached to this step. Extract it from the zip file.
Step 3: Installing the Post Process File
To do this, open your applications folder. Right click on the KISSlicer app and click "Show Package Contents". Open the folder Contents. Open the folder MacOS. Copy the postproc_009.lua to this folder.
Now remember that we have just copied the Post Process file into the KISSlicer app. The directory structure to the file should be:
Close all finder windows. We no longer need them.
Step 4: Finding the Location of Lua
We need to run in a terminal window:
It should appear like the screenshot.
From what it looks like, /usr/local/bin/lua is the location of the lua executable.
Remember where this is. THIS IS IMPORTANT!
Step 5: Adding Profiles and Other Settings
Download the attached zip file and extract it. There should be 4 files. Copy (or move) these files to the Applications folder. Overwrite as necessary. (or for you advanced users, copy the contents into the files that are already created.)
Step 6: Configuring KISSlicer
Most things that need to be inputted, are in the Slicer settings, BUT what we are concerned about right now is under the tab "Printer" and Sub Tab "Firmware"
At the bottom of the window there is a box for putting in a script for post processing the gcode used to run the printer. (Your input to this box will look similar to mine, if not the exact same.)
Type the following into the box:
/*path to Lua executable*/lua /Applications/KISSlicer.app/Contents/MacOS/postproc_008.lua "<FILE>"
where *path to Lua executable* is the path to the executable found in the previous step.
It should be similar to the screenshot.
Step 7: Configuring Pronterface for the PolyPrinter
Configure your Pronterface software to look similar the following. Click connect and you should be done.
Step 8: Print and Enjoy
I had one hell of a time getting this to work. Y'all should be able to get the printer to print something now.
