Starting new thread to cover this following article in MEW 347 and topic https://www.model-engineer.co.uk/forums/topic/mew-347/ to get it into place under CNC and make it searchable without clutter.

Also relevant threads : https://www.model-engineer.co.uk/forums/topic/3018-cnc-router-digitizer-laser-cutter-modifications-and-upgrades/

and https://www.model-engineer.co.uk/forums/topic/bed-for-6040-cnc/

It seems the Sable may be obsolete. However the key features are that it is so much smaller and therefore possibly more rigid than a 3018 and it uses a separate spindle and motor instead of putting an ER holder on the end of a motor again for more rigidity.
It seems therefore that a construction article on such a spindle is ideal ME content.
Also perhaps a second hand 3018 or collection of parts could be made into a smaller unit.

Even 2015 is bigger than most of the parts I would make by cnc (2015 is shorthand for 200mmx150mm) and I could get away with 50×50, well certainly 100×100.

I think construction goes a long way towards rigidity. The very cheap 3020 machines are not as capable of the better more solidly made ones. Much the same as a modern benchtop machine is not as rigid as old iron.

Also consider that your gantry needs to be able to span over the work plus any clamps or vice being used to hold it so another 50mm each side of your 50×50 part is not unreasonable unless you are just going to work on thin material that can be glued down.

Worth looking at some of the unpowered or even powered spindles that have the ER integral to the spindle, depends how much of a project you want it to be or whether you want to just get cutting.

I don’t use facebook myself, but this appears to be the place to look:

Easy to underestimate how big a cnc machine you need. My little Novamill is great but I would really like to be able to engrave a 300mm clock dial in one go. I found a way but tricky and risky.

I was also struck by the seperate spindle and motor arrangement and have been toying with a similar idea.

I have a Taig milling head that would mount without too much effort on my Fox Alien 3020 router. The current spindle is 300W but the ER11 chuck projects quite a bit and the Taig would be a much better solution. Not sure about the weight though…

Agree with author though, still learning new software and other things – CNC is not as simple as 3D print…

It really worries me that so many of these machines are suppled with component type power supplies. Thes are the ones with perforated metal covers and screw terminals. They are typified by the Mean Well units. They are only supposed to used when they are enclosed in a appropriate case with switching, fuses and filters as required. Without this they are unsafe. It is NOT ok to just connect them up with a bit of mains lead and screw them to the side of a machine.
They feature in the MEW article with no mention, so far, of enclosing them.

I’m not trying to be the health and safety “police” or spoil anyones enjoyment. Getting an electric shock or worse is not enjoyable.

Well after ‘getting into’ 3D printing and all it entails I am now going down the CNC router rabbit hole. As others have said the Sable isn’t available so I am looking into alternatives of which there are many.

My modus operandi is to sell of my never to be used again surplus tooling and invest the proceeds back into another interest.
