That pretty much sums it up for me as well Scott. I will add a little story. A young guy came up to our booth wanting to know how to learn how to write g-code. Graham gave him the name of a book or two and we started explaining it to him. Graham is the hands down G-code Guru for those of you who may not know. Any way, we talked to him a bit and then Graham walked him thru a simple demo program we had running. He explained every line and every command to him. We then told him to have a seat and let him run the program in single block mode watching the machine and seeing for hisself how each line made the machine act. That was worth the trip. Everything else was iceing on the cake IMO.  I meant to take a gamepad to try to stir intrest in the youger group but I forgot it.  . So many these days only have intrest in games and I'm hopeing that will add a little appeal. In my shop any kid I have ever shown my mill to really perks up when they see me jog it around with a gamepad. I would consider it a favor if someone will remind me next time I get to go.

This single page PDF will help you in understanding the coordinate system of CNCs.

Brett

Adding to this,

Rotational Axes The A, B and C axes produce angular motion (rotation). Typically, A rotates around a line parallel to X, B rotates around a line parallel to Y, and C rotates around a line parallel to Z.

2.2. Rotational AxesThe rotational axes are measured in degrees as wrapped linear axes in which the direction of positive rotation is counterclockwise when viewed from the positive end of the corresponding X, Y, or Z-axis. By wrapped linear axis, we mean one on which the angular position increases without limit (goes towards plus infinity) as the axis turns counterclockwise and deceases without limit (goes towards minus infinity) as the axis turns clockwise. Wrapped linear axes are used regardless of whether or not there is a mechanical limit on rotation.

Clockwise or counterclockwise is from the point of view of the workpiece. If the workpiece is fastened to a turntable which turns on a rotational axis, a counterclockwise turn from the point of view of the workpiece is accomplished by turning the turntable in a direction that (for most common machine configurations) looks clockwise from the point of view of someone standing next to the machine.

Guys, I have edited some post.

Bill, lots of good people here to help. Fernando is one of those. I hope after you take a break and come back the learning curve will seem much straighter to you. If you get upset in the future, take a step back before posting. We have a great group of guys here and we will keep it that way. I don't mind a little mud slinging if its needed and carried out in good taste but anything less will not be tolerated here. I truly understand your frustration, been there my self, I think we all have at some point. Biggest reason I believe lots of us are often here. Trying to lessen the pain of others. This forum is open to all ages and we need to try our best to stay cool. Not only for their benefit but for all others as well. I know it seems impossible at times, but you can get through it I'm sure. Were here to help.

Brett
