looking for someone in canberra to help build a cnc router

[bradeyk]

hey,
i have built one but one of the ball screws is bent, so am going to be order ing a replacement ballscrew, but i am increasing the size and was thinking of building it with aluminium, but i don't have any tools.

what i am hoping for is someone in Canberra that would love to help me design and build a moving gantry with dual on the x axis. 260mm x 600mm x 75mm (X x Y x Z)

i have the ball-screws and liner rails

cheers brad

Hi
Iam not in Canberra but would be happy to put together a few ideas, I would need more info on you linear rails and other equipment you have
Cheers
Chris

[bradeyk]

thanks

do you use any 3d design program?
i could make the parts i have
cheers

I have solidworks, I am currently in Canada at the moment and will be back in about 6 weeks,i only have my iPad which unfortunately doesn't have any cad software available, but would be happy to throw around ideas then.

What linear motion do you have?

[bradeyk]

rails,
sbr12 @200mm for z axis

sbr20 @400mm for X axis

20mm Pillow Block with 800mm or 900mm for the gantry.

and 16mm ballscrews

750mm ballscrew
330mm ballscrew x2
130mm ballscrew



i have designed the parts in sketchup

[Momentz]

So you want a cutting area of 400x750? You have plenty enough Z rail to give 75mm for z travel, it's with the x and y you would minus about 150mm for gantry thickness / width so on them it brings that down to only 250mm of travel on your Y, if you want 400mm cutting area youwouldwant roughly a 550-600mm rail and same on the 750mm you would want about a 900-950mm rail

nah the cutting area i want is around 270x600 which should be doable with the stuff i have. and what you just said

i have just chucked something together

Strongly recommend you rotate the gantry 90 degrees, to span the short dimension.

yeah, that would be smart, but i allready have the everything but the y axis from my current machine that i am scrapping

Why not buy a new one machine?
