New build help needed

[JAZZCNC]

Meanwhile I spoke to Vagelis(ba99297) member of your forum and he is already being a great help.

Vagelis is a very nice man he also makes Great wine please say hello to him for me.!!

With regards to your plans then my words of wisdom are Choose a sensible design don't go crazy regards build strength if all your mainly going to do is cut woods. Like has been said forget Steels and if you want best machine then I'll go further and say forget designing for Aluminium has well.?

Machine built to cut all materials is always a compromise, woods, plastics and softer materials mostly come under the same design class regards strength and cutting but Aluminium starts taking you away from what is optimum for this class. Which means pushing you into stronger heavier designs which start having negative affects on the machines main usage along with other negatives like.? Expense, complexity, performance with very little if any gain.

You don't need massive tube sizes and thick armoured plated tank like structures to cut woods etc. Aluminium needs it's own ideal design parameters and while it's possible to cut aluminium with a wood router it's very different to cutting aluminium correctly.
The design considerations for Aluminium which are mostly strength and cooling related both have negative affect on soft materials cutting with huge affect on your wallet to do correctly to suit both materials.

So design for wood is my advise and make it the best it can be for the intended purpose and leave the hard stuff for another build.!

Also don't need to design in Cad to the last tiny detail because things in the real world have a habbit of not fitting like they do in Cad.!! So just layout the basics to confirm lenghts etc and the design works also major components don't clash with each other. This does mean that you need to design with accurate component models or ideal models of the actual parts your going to use. Often I see people design using generic models only to find reality bite them when they don't fit in the real world like they did in the Virtual world of Cad.!! . . . . It also wastes a lot of valuable time that will be better spent building and learning than drooling at computer screen.!!

Good luck.!! . . . . . Oh and has the Lady's often find out Size really isn't everything it's how the tool is used which determines the pleasure.!. .

When capital controls are in place and sending money abroad requires a bloody committee to approve, you try to make it right first time. Hence I see CAD being imperative in Argyris' case

The comment of "Beware of freely available CAD models" is spot on. Not all Nema 23 motors are the same, not all extrusions are the same. Luckily Misumi allows you to download their CAD files.
Best work to the drawings that tell you the expected tolerance.

George Read what I wrote again and you'll see I Didn't say DONT use Cad I said don't get bogged down in trying to design to last detail. It's not required at this level and often IME helping others it actually slows down the process of building. Many times it leads to errors because too much reliance is placed on the Models and Cad without much thought for real world influences and differences.!

No argument with you Jazz and yes real world influences play a major role. I was just strongly reinforcing the need to plan and that tools are available for this.

No worries George just read like you thought I'd said DONT need Cad which wasn't the case. Like you I believe it's very much needed but only to a point.!

Thank you all

Clive, I meant to say helpful comments in regards to the dimensions. I will draw the base and I will add according to your suggestion and see how it goes.
Jazz, Vagelis is really nice, if he makes Great wine he is even nicer!!!

With wood and soft materials in mind I will try to design the base and post the drawings hopefully in a few days time. No previous experience with CAD(I can draw simple things) but I will try my best.
Plan is to start welding in January.

If it helps, the following is a Sketchup file, for the 8x4 router I built earlier this year

sketchup file here ( http://buzz.pensys.co.uk/pensys/gara..._cnc_mycnc.skp )

Dont be under the illusion this design is perfect, or suited to your needs. But if nothing else it gives the dimensions necessary to facilitate an 8x4 sheet with a Z carriage of 160mm

VAGELIS IS BACK!!!!

Vagelis is a very nice man he also makes Great wine please say hello to him for me.!!

Dean and Argiris thank you for your good words.
Argiris is the one who make me restart my project sooner as I expected
I explained him about the community of mycncuk.com and how the people here help help help, and the most important selflessly
Personally i feel thankfull ...

Good luck.!! . . . . . Oh and has the Lady's often find out Size really isn't everything it's how the tool is used which determines the pleasure.!. .

Dean the ladies often tell these words to the "small tool" owners in order to console them.

And a little story about "tools" that shows the superiority of the Greeks (here we laugh!!!) who think that we are the center of the world.... (here we laugh again)

An African and a Greek stand on a bridge and pee. Underneath runs a river. They stand on the bridje back to back ( the one cant see but only listen the other).
The African in order to vex the Greek says
"I feel the river is Cold today"
and Greek replies
"And deep"
Argiris good luck give us some plans.

Oh yes Vagelis this small "Tool" has been consoled many times and the pleasure was all mine. . .

Nice to see you back and would be even better to see more progress.!

Oh dear, I am not the only Greek on here any more. Vaggo, looking forward to seeing your cutting machine too.
