I found the issue, it was my Z limits set to tight. I opened it up to the max and it worked fine. I'm using Linux Commandcnc ver. 0.9.2. Linux is new to me but seems user friendly. It has a message icon that tells the user what is happening in the program and any problems. The answer to the Z limits was there, I just didn't know enough to click on the icon.
