Basically trying to move any axis the motors just made a sound https://www.youtube.com/watch?v=ajVZ2T6 ... e=youtu.be as if they could not move. the only potentiometer as high as halfway is the z-axis.
I began to wonder if some of the aluminum scraps could have shorted something in the electronics so i powered everything off and cleaned off the electronics just in case. 'I got to prioritize the case for the electronics,' I thought. I rebooted comp and plugged things back in just to have the same thing happen.
I reflashed the arduino with grbl 0.9 and connected through a serial console ('screen' on os x) and could get the settings with '$$'.

when i connect with the universal gcode sender though, i get the grbl prompt and can enter commands but there's no text feedback in the console

I'm guessing electronics are ok because they seem fine sending commands directly to the arduino and g-shield.
Suggestions as to what to try next are GREATLY appreciated!
thank you in advance for any advice!
