Hi To All
been looking through loads of info here. blown me away..
i am looking at building my own milling machine. but the main thing is cost! as always.
I have never under taken anythinglike this so its a first. I am used to using autocad both in 2d as awell as 3d (if that helps) other than that i am a novice. i am looking at routering out letters and pictures in wood.
If anyone can help or guide me in the right direction, with drawings or sites. Would be very grateful

Thanks Mike F
Ok any ideas as where to start ie plans for building frame work and/or materails
Is it possible to convert my cad drawings straight to a cnc router. or do i have to concert them to a different format. if i am able to programme straight fro autoCAD that would be a big help
No, you would have to get a CAM program to create the toolpath's needed to mill your part. the CAM program would create GCode and that is what the CNC controller reads to do your milling.Originally Posted by pinemartin
any advice on which would be cost effective to translate my cad drawings to cam to enable me to use the cnc
depends on what your willing to spend. there's opensourced cnc programs out there (opensourced means free for the most part) then there's the hobbyist programs (like BobCAD-CAM) which aren't that bad in price, then there's top of the line cam programs like surfcam. A quick search on google for CAM software will give you millions of hits.
If you have AutoCAD 2002 or newer, I wrote a macro that will export g-code from AutoCAD.

could anyone advise me what the basic components are that i will need besides the computor and my router. I understand that i will need to be able to move in both the x & y axis and Z. i have a design for that, and i have read peoples remarks concerning materials. what i trying to locate is a site that may show me the equipment i will need, and what plugs into what... Now i did say i was a novice
I'd recommend downloading Joe's 2006 plans and the JGRO plans and study them Both should give you a good idea what you need.

Basically, you'll need.
Machine control software (Mach3, TurboCNC)
Motors (steppers or servos)
Motor drives to control the motors.
Leadscrews and nuts or some other means to provide motion, such as rack and pinion.

Thanks all
Just been pricing up linear rails Wow not cheap. hoping to make the x axis 1200mm x 800. Not being tech minded seems very heavy trying to work out wieghts etc etc. looked at bobcam seems to suite my needs with bobart as a attachment. Their doing a deal at the moment for all the software....if anyone is interested. Big thanks to Simso in australia for your help
Bobcad/cam are ALWAYS doing a deal
