diamond: RE: [DIY-CNC] Anyone care to check my plans over, before i order the frame parts?

Hi Julian.

Looks like it will be a nice machine when built.
I guess by your post that where you put the pictures
you are in the UK.

To get anything comparable it costs an arm and a leg to
buy a kit of parts from most parts of the world adding
on delivery and import costs.

So your design could just be the thing for me as an expat living in France.

Any further information on expected costs for the metal work would, slides
and
Leadscrews would seriously interest me.

Regards Peter

Hello,

Ive pretty much got the design of my new table sorted, but, before i go and
get the metal work cut, id really appreciate it if someone who had more
experiance than me could look over the details and tell me if im way off the
mark?

Its a moving table design, using THK KR33 units for the y and z axis, held
on a frame made of a mixture of 80x80mm extruded aluminium and 16mm plate.

The work will range from engraving anodised aluminium (new hemes spindle),
to isolation milling of pcbs (wolfgang engineering spindle), to routing of
steel up to about 2.5mm (kress)

The plans are here -

(extruded in yellow, plate in red)

My possible concerns are the height of the y-axis cross member that i need
to accomidate the work (the uprights will be drilled to allow lowering of
the cross member for other work) and the weight offset from the cross
member, once both THK units and the Kress (or whatever) are mounted.

So, yep, if anyone has any strong feeling that im going about all this the
wrong way, could they let me know, before i go and get the metal work cut? :

Cheers, Julian
