I have the DDCM6v5.0 breakout board connected and running successfully on mach3. However, after running many job for any random amount of time (5-120 minutes) this board stops communicating with mach3.. and I mean just flat out stops dead in its pathing. This is where I need to unplug the board, repower, and home.. very tiring!
I also get a good chance of being disconnected when I push the reset button in mach3..
I'm only sticking with this board because of its 6 axis capabilities so if anyone knows the answer to this problem I would give you a virtual high five!
