I just wanted to drop in and say hi. My name is Chris and I have a large format CNC about 40 minutes south of you outside of Clarksburg. If you ever have parts that you need cut, feel free to give me a call.
I will be making a laser engraver at some point, but I need to pay off the behemoth I just built first
Feel free to PM me if you need any help with materials or supplies, I have a lot of leftover stuff from my CNC build.

Well, I made a pretty good mistake this time. I got my arduino installed and wired permenantly and was in the middle of diagnosing a problem when I messed up. I noticed that one of my drivers was only driving in one direction. When I examined the chip, I noticed that one of the pins wasnt' soldered on and it was the direction pin, so I took the pololu driver out and soldered it up and put it back. What I didn't notice is that I installed it backwards! I know that installing it backwards is a no-no and I even reminded myself to ckeck and doublecheck, but I got distracted by something in the middle of installing it and I forgot to double check. Well needless to say it fried really quickly. It got really hot and it was done for. I took the driver out and switch in one of my good ones (installed in the right direction this time) and ironically, it only moves in one direction so I mucked up something on the driver board too. Switching the driver board back, it works fine on the other axis. So now, I have no X axis
Just in case you didn't believe the instructions, it will mess up your board and driver if you put them in backwards.
Bart: I need a new driver and need help figuring out what else busted on the driver board.
