Come on down to the Seattle Mini Maker Faire at the Seattle Center Saturday and Sunday June 8th and 9th 2013 – I’ll be giving demos of the Shapeoko CNC mill featured on this site. See you there.
I’ve fixed a problem with Grbl Controller where it expected Grbl to reset upon serial port open – some devices like the AlaMode initialize once and when you connect, there is no version response. The fix involved sending a Ctrl-X if no response was detected.
The AlaMode is an Arduino-compatible board that stacks on top of the Raspberry Pi and communicates serially through the GPIO bus.
Checkout my writeup on getting the AlaMode running with Grbl
