So I recently got my C-Beam up and running, but the xPro seems to become unresponsive randomly, though never in the middle of a job. It won't work in the morning but I'll try it later, and it runs like there was never an issue. I did use Grbl Controller briefly while setting up the machine (jogged the machine and adjusted a few parameters) so this may have been the kiss of death, but I wanted to see if anyone else had this problem before getting another driver. I've switched to bCNC, but the xPro still only works some of the time. When its not working, the raspberry pi is able to see the xPro, I can select the correct port and it will display the version (v0.9j) but then it freezes up. I'll hear two clicks from the steppers when I attempt to connect, but I'm unable to do anything (jog, see parameters, etc.). When I was still using Grbl Controller, it would display "Wait for ok failed". Any advice is greatly appreciated, I'm new to CNC so the solution may be obvious or completely not related to the xPro! Thanks
Thanks for the response, but I'm still having trouble. I swapped to the macbook, got a new cable, and I'm attempting to reflash. I think I've got the right board/comm selected because when I pull up the serial monitor in Arduino IDE, I see the GRBL version displayed (and it freezes up like before/doesn't dump settings etc). When I try to clear the board with the code from Arduino's site I get the following: Arduino: 1.6.12 (Mac OS X), Board: "Arduino/Genuino Uno" Sketch uses 764 bytes (2%) of program storage space. Maximum is 32,256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables.

This seems like an improvement since updating my drivers where the only error I got was resp=0x00 My apologies for this big wall of text, maybe I should go to the Arduino site. . .
