Luke11CNC Build Log ,I'm so naïve

Yes Jonathan Image 7 has my display gantry and It's just been sold to help pay for the cnc machine But I may have a length spare would you like one ??

what would you suggest for the bearing support as I was just going to mount the gantry sides to it ??

That's a generous offer... how long is one length and what diameter/wall thickness/material are the main 3 tubes?

Difficult to say really. I used 100x60x5mm steel RHS which would be better but still not ideal. Aluminium extrusion is almost certainly the best option. You could just use solid blocks, but that's a bit crude and probably more expensive than two small lengths of extrusion. You just need to think of some construction that is strong in that direction.

Hi james,

Please excuse if you have posted this info in earlier because i've not read every post just flipped thru. What are you using for a gantry.? Do you have a general drawing or sketch of the overall machine as you would like it complete.?

I've been looking at the pics and think this the layout your going for please correct me if i'm wrong.
The bed will be down where the MDF is layed in pic 7, gantry it will be driven with twin slaved steppers which I presume will be attached at each side directly to the end of the gantry, by this I mean NO lower gantry cross piece. Presume ballscrew on Y axis.

I'm also presuming the bed and frame are not yet complete thou if yes then I see some areas that would concern me and will definaitly cause problems when machining.

What do you intend to mainly cut with this machine.?

Cheers






From the pics I'm thinking you plan to use the
Cheers.
