Steel frame cnc router design/build

**CraftyGeek** · 10-08-2013

Thanks Dean,

At the moment I was thinking more for the less important parts - motor mounts etc as it will make life a lot easier having a reliable local source that I can nip into to get the occasional piece without any postage costs.

I've seen AW mentioned in several build logs & have them bookmarked already when it comes to the important parts. It seems the narrowest width for the Ecocast is 100mm which may well make a design decision or 2 for me as well...although this could be an issue when it comes to mounting the Y rails on top/bottom of the gantry?

I assume that 5mm Ecocast will be ok for the rails to mount to?

Because using supported round rail then I wouldn't bother with Ecocast has the rail base will have more error than the steel. You only really needed plates between when fastening to Ali extrusion. If that's your plane then just buy normal Ali about 10mm.

If your meaning 5mm plate to sit on bearings then NO you'll need absolute minimum 10mm, 15-20mm is the norm.
