My first CNC Router *PAULIC* (the machine)

[kingcreaky]

Hi Paulus.
ive been reading your posts :D

Im no pro though so bit reluctant to say anything. But as nobody else has Il tell you what I think

Everybody who joins here, including me. Says, "I want a machine that can do everything!. Foam through to ali"

You can cut ali with a blunt spoon.Problem is it will take ages and it wont look very good when youve finished. As youve mentioned jonathons machine above youve obviously read his thread. Im sure he will agree with me by saying his machine is designed to cut ali therefore wouldnt do the best job of cutting foam? hope im not treading on toes saying that!

From what Ive learnt (see above comment im no pro!) is that your much better to pick a target material and make the machine cut that. For example If you plan to cut ali. The machine needs to be absolutely rigid in which case I suspect your Y/Z design holds the spindle too far away from the Y axis.
ALso, cutting ali doesnt require speed.

MDF (not sure if they call it that in the states?) requires faster movement to avoid burning. same with acrylic.

What im getting at is, your much better trying to focus on one material. design for that and its a lot easier for people to make comment on your design at present perhaps nobody is saying anything because what your trying to achieve will simply not work (very well)

Although credit is due for spending the time to do these drawings, il be honest, i cant visualize it very well and this may also have a bearing on others not saying much.

Read reviews on those drivers before you buy

download google sketchup, 'think its called Trimble' nowadays. Its free, its 3d warehouse or whatever gives you all the components (linear rails ballscrews etc) and perhaps with a 3d design you may get some bites from the bigger fish.

Keep posting.. beauty of the internet is even though you think your talking to yourself, your not!


whilst typing this... you've had a bite!
