Hey m8, I'm busy atm but asap I'll get you some basic dimensions of the base if you'd like, I can't find the pdf atm that has the info. But basically yes it needs to be either floor mounted or mounted to something solid enough to take ~4kg ~9 pound that wants to throw itself around, the x & y axis throw on it is massive too! this is good cause you can use the software to make endstops so you can tweak the throw length of the x & y axis.
