Hi,

I'm new to the forum and in the planing stages of my own cnc router. I'm planing to start with a 2' x 4' cutting bed and use materials that will allow me to upgrade it to a 4' x 8' when i have the space. To do this i'll use 3" x 6" aluminum profile, rack and pinion rail attached to the stepper motors with a drive belt (except for the z axis) and other materials that can be extended or deconstructed. The design is based in part on "Joe's design" (seen being made hear)

It being an American video and being based in the UK I have found most of the equivalent parts except for the X and Y motor mounts that link to the rack and pinion rail.

All in all i think i have the design sorted out "in my head" and will start to drew it up in CAD asap.

First of all i would like to ask if anyone has come across this design and what they think of it?

And second, what is the best hardware to buy for something that will be enlarged in the future (NEMA 34 N.m. 11.2 stepper motor, stepper motor Drivers and so on).
