looks like you have it all worked out, and plenty of space & a kettle!!. Keep the pictures coming..

Should be a nice little build that. Looking forward to seeing it come together, keep us posted.

Nice little wood cutting machine. Don't forget the energy chains. You might just fit one under the X rail on a shelf bolted to the extrusion.
With the single ballscrew on X try to cut jobs on the centre line of the machine to reduce racking.

Nah there will be no problem cutting off centre in wood with this design at this size. I've built several know using almost identical design (probably because mikey copied most of my router design. . Lol) and they don't flex while cutting woods, even hard woods.

That said I wouldn't use single screw for cutting aluminium or really deep DOC cuts in hardwoods as then there is potential for some racking.

There is just enough room for energy chains between profiles but needs certain size. It also doesn't need a shelf as nearly half the chain can be supported or bolted to the profile and the remainder easily handles the weight of cables etc.

Hi Jazz - I merely took the good advice that you offered !!!

Once the machine is up and running (and doing some useful work) I will upgrade to twin belt-driven ball screws.

I admit that the energy chains location is a bit of an afterthought....

Thanks
Mike

So you saying you haven't copied anything from the L shape profile gantry Gantry or the offset drop Z axis Layout or the profile base with aluminium end plates I use.?. .

. . .Ok.!!!!

If thats the case then sure you must have accounted for the gotcha's that I see and encountered.!!

Hi Jazz

I have to ashamedly say "yes" but good design and good principles are always worth following!
