so onto my next build ....
my rails have arrived , yay so am just waiting for the motors and drivers
still have to select a spindle, but im quite set on a chinese 3kw water cooled , i had a 1.5kw on my old machine and was quite impressed with it even though i blew the VFD up :S oops
cutting size is 2400x1200x200 so that a std sheet will fit in the machine ..
25mm rails on X Y and Z ..
Z will have a 20mm ballscrew X & Y will be on mod 1.5 rack and pinion
10:1 step down boxes on X and Y with a 26t pinion , Z will either be belt with 1:1 pulley, or direct drive with coupling
rapids will be around 15m/m , will probably speed this up in due time
the frame is quite conservative i think ... and now i dont know if i want to go bigger rectangle section or just stick with the 76mm square
all steel build , gantry sides are 6mm steel plate laser cut , two 76mm box sections for the gantry
Z plates are 10mm with another 10mm to space out for the bearing blocks
epoxy self leveling construction method will be used
where does it stop :D
i will mainly be cutting wood and plastics (corian - acrylic) so i dont need a terribly stiff machine ... for now ... my next build after this will be for aluminum
