PreSales questions

Hi,

I am looking to buy an 840 complete with MM toolchanger and some other bits, and have some questions:

1.) I'll be using Fusion360 and a USB version of the 840; Am I correct I will only need WinPC (full) to get this running?
2.) Can the toolchanger be added to the MM1050 at a later date, or do I need to decide now which version to get?
3.) What is the switchbox option on the 1050+toolchanger, is this required to operate? It is not quite clear what the function in for just the toolchanger.
4.) What collect size do I need for the router bits you are selling?

Thank you for your time.
