HI !
So here is another DIY plasma project (hopely lowcost). Working area is approx. 4 x4. 3 axel, i hope you get the idea from those pics (Z-movement is still under progress).
Do not hesitate to comment I appreciate all kind of comments.
Some specs:
Logic: PC, Smoothstepper and Mach3,
Electricity: Maybe Toroidal transformer,
Motors: three NEMA 23 steppers with Motion-drivers.
As you can see, I have planned motors inside the frame, atleast its fine with solidworks :P Those linear movements is executed with ballscrew. and supported with linear guides (like this http://www.designworldonline.com/upl...%20bushing.jpg ) Its pretty cheap,accurate and light.
Whats on your minds ?
