yes. i test all my programs and screens on my pc inside before i transfer outside to my mill pc.
not having your motor tuning etc setup properly will give your innacurate estimated runtimes and simulation speeds.and so forth, i would find someone running the same hardware as yourself with the same controller and use his xml file in your install.
I test clients files (and mine) like this when they crash their hardware. easier to see visually where something is going wrong that to pour through 100 000 lines of code.
