Yes, thank you for all the help. I actually did finish all the wheel/plate assemblies and everything made sense once I started building them. I am just going to mount all parts together now. I am curious about stop switches, how many do I need and where should I place them ? I didn't see any of the builds mention stop switches. Are the motors or drivers capable of detecting when it hits an end or does every corner need a stop switch?

 

I actually have everything wired up and need one last help, am I supposed to wire both x axis motors to the same output or can I control them together through different outputs?
