hi,
i have been looking at making a cnc machine,
i am a uni student studding software engineering,
right now i have made a simple fixed gantry using printers,
but i need more strength and precision.
[nomedia="http://www.youtube.com/watch?v=DBIhvvAZjak"]YouTube - CNC/Plotter made from Printers[/nomedia]
these are the parts i have ordered
SBR20-400mm(2supported rails+4 SBR20UU bearing blocks).
SBR12-200mm(2supported rails+ 4 SBR12UU bearing blocks).
4 items SHF20 shaft end supports
linear bearings blocks 4 SC20UU
3 anti-backlash ballscrew RM1605-400mm-C7+3set BK/BF12
1 anti-backlash ballscrew RM1605-190mm-C7+1set BK/BF12
4 couplings to suit motors with a 6.35mm shaft
as in the video i have a arduino controller which i have been programming, with my own software on the pc to send the g code, i plan to add SD support
i have some steppers lying around and i plan to use them,
but if there not enough what size would you recommend,
i plan to mostly cut wood,plastic,PCB and maybe some AL.
i also want to make this into a 3d printer
i am not sure what to make it out of
i have been thinking of mdf/hpde
i have enough tools to work with steel/wood/plastic
for a moving gantry i have decided to go with twin x axis.
but what should the layout be,
i have two designs.
