Upgrade to 1000x1000 x-carve

hello there inventables community

im natt williams from australia i have purchased the new x-carve 1000mm x 1000mm with the dewalt 611 spindle and all the bells and whistles you can possibly get for it i haven’t recieved it yet but my plan down the track is to upgrade it to a larger size 1000mm x1800mm but first of all i want to get it running and everything spot on before i do then do the mods i would appreciate any feedback at all on how the best way is to do it and what i will need to do the mods and also calibration?

thanks in advance
