If your machine is moving correctly  then try using some of the wizards to do basic cuts until you get into the swing of things.
The learning curve is steep but you will get there :)

Nike and Bob,
Sounds like your both going to have to start reading a lot. Would be helpfull if you had a friend who can give some machining basics.
CNC machinng is not plug and play and there is no short cut to it all. I may add that it can be as simple or complex as you wish.
Crawl for a while and walk before you run and by all means be safe about what you do.

I have tried a couple wizards in Mach 3 one worked great the other, CUT CIRCLE by Kiran, did not. I entered the X, Y center locations, circle diameter, depth, tool diameter and adjusted the feed settings and Z heights. When I clicked on Post G Code, the toolpath display just displayed a large arc on the screen around the center of my X,Y home settings. I was assuming it would show the circle at the X,Y location.

Here is an example of my settings: X & Y set to 4.0, 1.0 for the circle diameter, 0.50 for the depth and 0.125 for the tool diameter.

I have gotten all the Axis' moving in the right directions and the correct distances. I have hit the regen toolpath button before running the program but nothing changes. Any ideas??
Thanks
John

Sorry, no help, but maybe a little encouragement;

I was sitting with a new (to me) CNC mill 3 weeks ago without a clue. I could make the axis move and that was about it. I am good with my CAD program in both 2D and 3D (Turbo Cad), very proficient with a computer and have a few years (hobby) experience manual machining.

Since that time I've viewed every video offered by the makers of the 2 new programs I had to learn, Visual Mill and Mach3. I've read each pdf manual and help file from cover to cover and poured over each program's web sites - especially the forums.

This weekend I successfully made 3 simple 2 1/2D parts without error. It is hard to imagine how good that felt. (The first week I drilled 4 3/8 holes in just over 5 hours - and they were not in the right place!). I've just begun the learning process, but feel I've hit an "Ah Ha" point. A lot came together all of a sudden and I'm back to hands on learning and much less frustration.

Like the veterans already said, keep at it, read & study it.

So how do you like Turbo Cad? I'm looking for a CAD/CAM package as I'm using Google Sketch-Up to do a project I'm working on. I see TurboCad is on sale for $99 and you get a bunch of training videos with it.

Johntech,
A couple of things. With the basic version of TurboCad I don't think you get any 3D capability. That only comes with the higher priced versions (I use Platinum Pro just because I needed it for work - about $1,500). I am able to do everything I need with it at work (mostly 2D) and still able to save some $ over AutoCad.

However, I'm not sure that if I were buying a program to use mainly for Cad/Cam that it is what I would chose, not sure it isn't either. To be honest, I'm not experienced enough with Cad/Cam (just a beginner) to know exactly what would be good. I am just using TurboCad because I have it & there is no learning curve for me to use it. Enough learning with the CAM end of the process!

Sorry I can't be of more help.
