Need Help!- Question on Travel Distance

[yury89]

Hello everyone,

Can anyone please tell me what is the recommended travel distance of x-y axis, of 3-axis mini/desktop CNC router, to machines a square 30cm x 30cm alumunium and 10cm thick?

>30x30x10 + the diameter of the cutting bit you intend to use. Rails would have to be longer than those dimensions by the width of the carriages / bearings.

So, will 1 meter length (total length, end-to-end) of both, linear guide rod and ball screw, would be enough for this small project?

i've found that depends on the materals you make it out of.. MDF or PLY you will need to add about 20cm each for X & Y for the carrages & Axis rails etc..

it also gives you a bit of wiggle room (clamps etc...).

so to do 30cm x 30cm i would do a 50cm x 50cm x 30cm machine at least or a 60cm x 60cm x 40cm to be safe..

just my 2c worth as i'm new & learning stuff all the time too.. and size is a major one.. i err on the too big then the not big enough.

Is this the design you intend to use? Unsupported rails will not do the job.
