Hello! I recently acquired a Robo3D printer and went to town getting MatterControl setup with all my personal tweaks and exotic filament settings. After getting tired of dedicating my laptop to the printer I decided to add one of the readily available LCD screens with SD card support. To my dismay, after installing the screen I found out MatterControl doesn't support saving of GCode. I am going to be honest, what kind of sick joke is that? Anyway, being too stubborn to switch to one of the other many available tools I decided to modify MatterControl to add in support for saving generated GCode, while at the same time fixing the slic3r engine that doesn't work in the mac client. The patch is available on my github for anyone that may be interested: https://github.com/beeedy/MatterCrack Installation instructions can be found in the readme and were made to be as straight forward as possible, also this was written entirely in python so I recommend taking a look through the source if you have any concern or curiosity about what it is doing. I highly encourage making a pull request if you find something you want to fix! Not sure if anyone still uses MatterControl besides me, but figured I would post this incase!
