Recently I assembled my Shapeoko machine, we used Grbl shield with an Uno for the same.

For 1-2 weeks everything worked perfectly then once when I tried to work the machine, the serial communication was not working. I tried to replace the 16 MHz oscillator because I thought the problem might be with the oscillator since the LEDs were not blinking but they were lighting up.

Did you mean 16MHz and not 16Hz? – Greenonline Jul 29 '15 at 06:15
Maybe the 5v regulator? Hard to say without the symptoms. – daedalucian Aug 05 '15 at 18:21
