Lets eventualy start this CNC - MKI

Can anyone recommend a good supplier for 45x90 & 45x180 profiles ?

Also cut to size Aluminium plates 15mm & 20mm ?

How about this http://www.motedis.co.uk/shop/Slot-p...91_999994.html they cut very accurate to size

Thanks Clive!

Yeah - I've been looking at a German company: http://www.dold-mechatronik.de/Alumi...er-i-typ-b-typ

Turns out, the link you posted get their stock from the site above :)

Thanks for the advice re bolting it all together. There is one bit that has a 'locked-out'

I've already started on the 20mm adjustments.

The spacer blocks will be there until I have the ability to machine out the Z plates. (and as you suggested, the brackets that hold the ball nut to the Y plate supports.)

Thanks again.

Will post next version soon... (no use calling it final.... ever, no such thing hahaha)

Ok,

Re-Designed so all plates are 20mm (except motor mounts, those I have at 6mm - might end up as 10mm...)

I did what Clive suggested and put each piece together as I would.

I should be able to get away by having recessed bolts for the entire Y/X axis, and being able to bolt everything without tapping :) [Y will need tapping]
[ The bolts holding the X plates and bearing support (160mmx50mm) together, can be bolted from the back to the front ]




I 'think' I'm getting nearer to finally placing an order of exact lengths of components :)

Thanks all!

I can't take the credit for that I think it was routercnc.

Not sure why you need the spacers on the Z plate as it would be better to recess the front plate and that would get the spindle nearer to the gantry.

edit it looks like you have the BK bearing at the bottom end of the Z screw

That would be the long term plan - but unless I grind out the recess.... I won't be able to do it now.

Unless... I could rig up a temporary motor mount and bolt the linear rails to it and do it by hand.... hmmm...
Another idea is to rig up something and do with the hand held router.

Suggestions?

For now, I've gone with mostly square cuts, (that's how they are supplied), and then once the machine is up and running, start cutting bits and then replacing them. Although, I will try do do most of it by hand with the router.
