Hello, I would like to build a CNC able to work on a full MDF sheet: 2440 x 1220mm. By digging into this site I think that both OX and WorkBee design could be adapted to this dimensions but the main difficulty will be to find the linear rails in 3m lenght especially the C-BEAM one. First all, is it correct that those two design are two good candidates for scaling or am I wrong? Are they other design that could be more adapted? Are there some advatages from one design comparing to the other? Are they some other attention points or modification I need to do to be able to scale those machines? I am a complete CNC newbie. Does someone know where I could find a 3m lenght rails not too expensive? I have found the V-SLOT one in France I can probably find it cheaper somewhere in europe. Regards, Benjamin V.
