I'm not into jealousy but I am realist and know there's no way he's measuring 0.02mm over 3000mm like he's claimed in the past or even over shorter distance.!! . . . Ask me why.?

Ok I'll tell you.!! . . . . . Would be bloody impossible because he's using C7 ballscrews From China which at best will only give 0.05mm over 300mm. Then throw in few belts/pulleys etc and this goes down further.

So who's fooling who.?

When did I make that claim? This is my first build and I don't see that claim made :/? I think you grossly underestimate my realism..

Crossed purposes wasn't talking about you with that statement.

I just like the way you assumed I needed to be more careful. What exactly gives you the impression I haven't been?

Because I'm not blind and can see there's been no machine work done on any of those surfaces or any thought regards rails being on same plane etc.
I've never yet seen piece of angle iron that is perfectly flat or 90deg and you are bolting straight to the face of one.

Then we have the heat put into the metal which can clearly be seen. You can Stitch it with pigeon Shit and beat the shite out of it all you like but it will still be warped or twisted in some way unless you take other steps to correct it.

All these little things will bite and like I've said your lucky your using round rail. Profiled linear rail would just not tolerate this level of in accuracy and bind up solid.

Edit: Just to be anal and prove my point look at this picture and tell me whats wrong.?

You are referring to me shaping it? I don't see the problem? what are you suggesting? (genuinely asking)

Having a good read of this thread I'm rather speechless and even more speechless with the commentary that goes with your posts Slixxor, you can educate yourself so well on the internet of the basics it' just takes a bit of time to learn and absorb. I'm not going to pick up on individual things because would be here until the 1st of January. This is not a good advert for someone to have a go at home. You are one brave man to post this publicly.

Im confused what bewilders you? Can you elaborate? I dont see how my build is different to any other. And my comments are far from offensive. Do you just not like the design. Im confused

If you read it again Dean was not referring to you with the above It was a claim made by another on the forum.

Hence the reason I will see how it goes when it's done. I've endeavoured to make it as square as possible on all axes and feel comfortable that I've managed to achieve that within the best of my ability.

At the end of the day that is all anybody can do. Looking forward to seeing the first cut

You sir have a much better personality. I think JAZZCNC needs a holiday by the sounds.. Clive, legend as always ;)

Oh so your YES man well tough luck because if it's shit you'll get told it's shit by me.! . . . . Like wise if it's good I'll say so as well but I see nothing here that's good.!

To be fair I've been very kind on what I've commented so far, mainly because not got full week spare to list all that's bad.!

You are referring to me shaping it? I don't see the problem? what are you suggesting? (genuinely asking)

Nothing to do with shaping and every thing to do with being warped and surfaces not on same plane. Then generally just weak poor rough arsed engineering which for CNC won't cut it.
Just because your using steel doesn't mean it's stronger. If the design is weak and poorly built which this is then doesn't matter if built from 2" steel material or 0.1" aluminum (note Ref in American just to so can understand . .lol) you'll never succeed in achieving accuracy or reliabilty.

Look again at this Pic for just few bits of whats wrong.!
