I'm wanting to build an OX but with a bit of a larger working space... I would like to be able to work on a 4ft x 4ft square material with a machine approx 5ft x 5ft I was planning on going with the standard OX design but with longer struts for the X and Y axis. Any advice on this? Will this design be scale-able for this? Anything I should consider as I move forward with my build? Thanks for any advice!
