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?

im sorry but i don't understand.

[JQ Laser]

I mean you can buy a machine at a good price

im sorry but i don't understand.

i have redesigned it in solidworks, all parts ordered

[bradeyk]

i have now started construction

Nice work - followed your threads over from another older one.

I am not sure if these guys are in your area or not, but they also mill pcbs. In fact, they are my primary PCB supplier, both for proto and moderate size production runs. ( I do some custom LED lighting work)

Thanks for posting the pics and build thread.
