Remote Control Makerbot

thingiverse

A Thing Rube Goldberg would probably be proud of. This originally started out as just a camera to be able to watch my Cupcake while it printed from another room and grew from there. After getting an automated build platform I got an idea.. Adding an Arduino Mega with and an ethernet shield, the webcam gained pan/tilt and the Cupcake got the ability to be turned on/off/reset remotely. Revar's keypad, 16 optocouplers, a second display for the keypad and another arduino later and I got even more control over the bot. Then I included a Mac Mini. A webserver, Applescript and RepG later and I was able to upload STL's and automatically convert them to s3g for the bot. Then I thought to myself why not automatically move the s3g file directly to the Cupcakes SD card? Electrically switching the contacts didn't work as the wires were too long. Then a wise guy at work joked about using a robot arm to move the card from one slot to the other... The end result is an over the top system that allows me to print completely remotely. The MacMini hosts the web pages through which all remote control is done. When an STL file is uploaded, it is picked up by OSX folder actions and passed to the Applescript to start the conversion. This is also the trigger for the robot arm to pickup the SD card from the Makerbot motherboard and move it to the MacMini's SD card reader. Once the STL is converted to a s3g and saved on the SD card the arm is then triggered again and the card moved back to the Makerbot motherboard. The print can then be started using the virtual version of Revar's keypad. Video of the arm moving the SD card:http://www.youtube.com/watch?v=MKgSLGnK1Ls Instructions The conversion Applescript has been attached for those interested. It was created for RepG 24 so may not work with 25. The attached STL allows the mounting of a Lynxmotion pan and tilt onto a standard tripod. A rough BOM: 1x Arduino Mega 2560 1x Arduino Pro Mini 1x Arduino ethernet shield 16x 4n25 optocouplers (or similar) 1x Lynxmotion AL5B Robot arm (the one I used has had some mods) 1x Lynxmotion BotBoard2 1x AtomPro28 microcontroller (for arm) 1x Modtronix Keypad and Display multiple 5V relays (power switching for bot as well as for the arm) I seriously don't expect anyone to duplicate this, you would have to be mildly insane. There must be easier ways to do it.
