Last night’s hacknight had a special visitor: Sonny Jeon, the developer behind grbl – “a free, open source, high performance software for controlling the motion of machines that make things and will run on a straight Arduino.” It is loaded on the Arduino running our Shapeoko 2 Mill (thanks, #INVENTABLES!) as well as many many more machines worldwide.
He emailed us, then came in to donate some CNC equipment & brewing supplies. Sonny had great discussions with Aaron & Morgan & others, and he even updated the Arduino running our Shapeoko to the latest version of grbl (freshly released in the last day or two)! This new version is much faster, and we can already see the difference in movement of each axis.
…Sorry, Walter, but none of us thought to get a picture, durn burn it! Instead, please accept this sketch from his blog (a cropped version is also on his github page):
