ozymandias 7 Posted March 7, 2012 Share Posted March 7, 2012 I've had a Makerbot Cupcake CNC for a while now and have been wanting to convert it from the current arduino-bobino-fee-fi-sanguino controller to lightweight and modular MSP430 subsystems that would be useful in other control and robotics projects. currently i have beta software that takes in UART data from a computer (i'm using GTKterm in linux) to the launchpad, where a G2231 controls chip select bits and resends the byte to (currently 3) other 2231's. What i'm planning to do soon is modify the Makerbot to "close the loop" as far as control. Currently, you only theorectically know what state (where each bit is) by knowing what you've told it to do already; the "open loop" control (usually bad). I've put up beta code in the code vault and i should :!: have proof of concept up and running by the end of the week. larsie, cubeberg, thanhtran and 1 other 4 Quote Link to post Share on other sites
