concretedogHappy as a pig in muck as they say... in the #doghouse early this morning. Tunes on (some 90's DnB cos I'm that old!) and wiring up a LinuxCNC control setup with a raspberry pi 5. For an upcoming @rpimag article. #CNC #making

Avian Hang Gliders@concretedog @rpimag What's the CNC?
@concretedog @rpimag Cool, that's a large format one for cutting wood? I've got a Nestworks CNC on the way (I supported their Kickstarter), opposite end of the spectrum, very small working envelope but rigid for cutting metal. I'm very much hoping that it'll be a tool not a project also!
Btw have you ever talked to @goatchurch about the triangular CNC he worked on? That was a really neat project, I'd love to see progress. Rotational axes instead of linear, spaceframe design so rigid but light.

@avian @rpimag @goatchurch No this is more a smaller one with good precisiion from the ballscrews.. it does cut wood but also is capable of alu, and I've even tormented it cutting mild steels like EN1A.... but its pretty slow for that!
@concretedog there's a bit more about it here:

I could imagine this being developed into something with precured CFRP tubes joined by machined metal nodes to make the frame. Since you could machine the nodes with the same machine it would be like the original RepRap project which bootstrapped 3D printing. Could be very cool. Unfortunately, yet another idea for a project I'll never have time to pursue!

@avian I'd not seen the nestworks before... looks interesting. Nice to see after Carvera more people are trying desktop CNC products. Do you know what flavour gcodes it will need? Are they supplying software or at least post processor info?
@concretedog I also looked at the Carvera but this edged it on specs. It has it's own (proprietary :-( ) software, which I'll certainly use initially. Only if I can't get it to do what I need will I start tinkering with other options! As I say, tool, not project (I hope!)
@avian Carvera have had a fair few teething problems and I see a lot of mutterings about cloud connection issues for software stuff. But it's a cool thing. I'm kinda naturally skeptical of such small machines and metal machining ... comparing rigidity to even my smallest manual milling machine rigidity, it's magnitudes of difference!
