Is there a preassembled kit or list of parts I need to order to enlarge my 500mm XCarve to a 1000mm?
You should be warned that such a procedure would result in a dangerous concentration of free radicals in your closet. Free radicals are highly reactive items which recombine/reassemble and are hard to control which results in the loss of space and money. The firsts sign you are affected by their affects is the phrase “ya know, I’ve got almost everything I’d need, except for…”
The mostly likely outcome of this procedure is not an upgraded machine, it’s two machines sitting next to each other.
