Torin,
If you are really set on doing offline programming, the on,y thing you can use is software from Motoman called MotoSIM. This software will allow you to make programs offline and in a format the robot can use once loaded in. To load the programs you need FDE for Windows. Both software packages are only available from Motoman and both are not cheep.
Please remember a robot is not a CNC machine. It is a six axis articulated robot. The software to drive each of the six axis to move a tool from a point in three dimensional space to another point in space has been written by the robot manufacturer. They will not give up this code for you to play with.
You mentioned you are taking your robot "home". Is this your house? Do you have three phase power in your house? Please remember MRC robots use the chassis as a common ground for all voltage reference. The robot is three phase but needs the fourth wire as neutral to your source. Be extremely careful if your are using a single phase to three phase converter. I have seen many people try to do this and end up blowing the converter in the MRC servo pack.
