Hello,

What do you think about the OX CNC from OpenBuilds ? I like it's design and the ratio footprint/work-area. I know that the belts aren't the best, and I think they should be replaced by ballscrews. With more bracing on the structure, it seems like a good design.

What do you think ?

Jazz, I hear you already :D

Cheers,
G.

Lightweight side plates!
I've just deleted 5 minutes of typing but Isembard Kingdom Brunel is spinning like a top in his place of rest!

Just make thicker plates then, out of steel even better :) It's crazy how when you British people post I always have to Google your slang :D

Sgspenceley at open builds is building an improved version, with linear guide rails http://www.openbuilds.com/builds/linear-rail-cnc-machines.1771/.

I was really only talking about the machine, not the electronics. Obviously I'd put my own control box and electronics.

Love it :)

This thread was really intended to see your opinion on the machine. I don't intend to buy one, but I was curious to think what you had to say about it. I heard you :)

With the square 20mm linear rails and RM1605 ball-screws specified at the end of that link, it looks to me like that is more of a build-from-scratch than a kit-thingy? Think it would benefit from RM1610 ballscrews on the X and Y axes though.

Definitely agree with that. The link starts as an evolution of the OX but ends up being a from-scratch version :)

I love this new public, flow of conciousness design process, when he types
"25th April
Major redesign today to improve structure and make it stronger."

I read
"I was a clueless knobsock yesterday with the engineering aptitude of a llama and I've just realised that, but I'm all better now!"

Priceless :D

What funny is that there's a huge group of people learning about CNC from the ground floor. They're basically doing the same thing that we did 12-15 years ago, but instead of making cheap machines from MDF and skate bearings, they're making crap machines from custom lightweight extrusions. And the first thing they do when they build their machines, is figure out how to make them better. They really don't have a clue.

Agreed Gerry but the difference being IMO is that 12-15ys ago things where a little different with very few people doing this so not lot of Info floating around. Which isn't the case Now.! . . . .These Muppets are just Lazy and don't want to read.

Is that the new material, (Active Perspex) Use the clear stuff so you can see what you are doing wrong :teapot:

I have said it before and I will say it again (and again, and again) that the real sinners are the cynical exploiters who sell their expensive, rubbish machines to people hoping to make a living with them.

The amateurs who are just blowing their own trumpet having made a CNC machine out of Lego and plasticine are an amusing diversion.

Has anybody heard of Sugru, I want to build a machine out of it (with foamboard for strength) to cut titanium with 10cm DOC and at warp speed.

Nurse ! Why are you locking the door ?

Cheers,

Rob

It's funny/depressing in equal measure as all the necessary information is now freely available to those willing to search and read around the subject, I suppose that's not as glamorous as publishing shiny renderings of shonky designs!
