Please Help! How to connect ArtCAM Smoothieboard and X-Carve?

I am an novice.

Recently I bought X carve with Smoothieboard and now am in great trouble cos I dont know how to connect it to work fine. I tried some solutions and broke Y+ limit switch.

Initially, man from which I bought it showed me that everything works fine, but I cant get same result. He used Pronterface to run G codes made in Artcam.

I dont have solution, so if anyone knows what to do, please contact me on my private mail

Thanks a lot.
