Very Great and complete topic. Thanks Tin .

I did found all my researchs when I started my Homemade CNC project.

A couple things that might help I hope:
-A Free 3D CAD software (under Linux, Windows and MAC !) is FreeCAD ( http://www.freecadweb.org/ ). Use it all the time for 3D model and can export many different format.
- To manage the CNC (and already mentionned by Tin) is Linux CNC ( http://www.linuxcnc.org/ ). You have to know that is it a free software. Moretheless you can run it either with live CD (to run it only when needed without any further installation on CD reader but can be slow) or installed it as a dual boot on your system. It means you can run either windows or Linux on the same machine without destroing nothing !
- As a Free CAM sofware you can use PyCAM ( http://pycam.sourceforge.net/ ). It will help you to create G-code able to be use with your CNC manager like Linux CNC or Mach 3 or any other (real) CNC. It is not an advanced soft but for a hobby stand point and specially for 3D carving can be a really soft to have.
-As a detail thing, regarding stepper motor, I have to dig with torque and speed. It is basic but it is things that you have to consider when entering in CNC. I put my experience on this video: https://www.youtube.com/watch?v=6riATIh-4Vg
-A previous topic detail the soft's workflow for creating part up to manufacture it: http://www.homemodelenginemachinist....47/#post227989

Laurent.

As we all know computer technology is constantly changing.
CNC is no different . A new and interesting option for the computer experimenter / Linux cnc fans is the Beagle bones black. And xylotek has a cape that has a 4 axis cnc breakout board built in . and they sell the linux pre loaded on a sd chip. so for about $ 100 you have software a computer and a breakout board. yes there are things you will need like a HDMI monitor , keyboard. Motor controllers, power supply, stepper motors couplings motor mounts etc . but google beagle bones black CNC and there is a bit out there. Exciting stuff to run a cnc off a $45 dedicated computer.

Well 'pends on the software . Free is cheap but not always the best value.

What mill are you getting ? many x-2s can and have been converted to belt drive and the spindle speed boosted to around 4K.

Hmm Nice looking machine and probably not a bad price.

Would be nice to know what the base machine is. Looks like a SIEG XN3 variant. but the XN3 shows a max rpm of 5K much more favorable to small tiny tooling. So I guess the next question is do you ask them if they have a head upgrade available or add a aux spindle for small work engraving.
IE mount a hand held engraver to the spindle. Has been done.
The 5k top speed would be nicer.
