I've been playing with a Smoothieboard back since it was in beta (both the hardware and the software) but never actually used it in production - just fooled around with it and contributed a little to the Smoothieware code in the early days.
Anyways, i've decided to take the plunge and switch to an ARM, but decided to overdo it a bit and go all the way - i'm switching to an Arduino DUE + quad core ARM Cortex combo, with a 7" screen for the UI and WiFi+LAN:
The lower board is an
UDOO Quad - quad core linux ARM machine with an integrated Arduino Due - the top board is a
RADDS shield. So far, got the screen working, Octoprint running, flashed Repetier onto the integrated Due, got Octoprint talking to Repetier... however, i hit a snag. For some reason, when i hook up 12V to the RADDS shield, the whole thing gets stuck in a boot loop - during boot, at the point where the Due gets initialized, it somehow and for some reason hard-resets the Cortex.
If anyone's interested, i'll continue logging the progress here.
