code help

[nfl2k2]

Here is an mspaint diagram of a simple CNC project I'm working on.

I want to create a txt file with the proper G-code to punch out four .250 in holes through the workpiece. Tool#1 is a .250 in diameter twist drill. Never done something like this before, I've found a few documents on the web that offer help, but I'm still having a hard time putting everything together. Could you guys point me in the right direction as to where to start?

(ex: how do I define the origin at (0,0)? How do I move the machine part to the point (2, 1.5) and punch out a hole at that location? How do I tell the machine to bring the part up .1 in and move to the next point on the workpiece?)

Thanks for your help!

I dont know what kind of machine your running but this would be the codes for our machines.

T1M6
G00G90G54X2.Y1.5M03S1500
G43H1Z.1M08
G81Z-1.5R.1F5.
Y2.5
X6.
Y1.5
G80
G28G91Y0Z0
M30

Of course the feeds and speeds need to match the material your cutting.
