Sorry for the late response. Just got back to my CNC today. As embarrassing as this is to admit, the problem was that I was hitting my limit switch! I think I have overloaded the machine in the past and that set me down this path, but this time was all my fault. Thank you for the help.
PS-I do have a fan and I am running a Meanwell 24 volt 8.5 amp switching power supply.
