help with gcodes

[turmite]

I am almost ready to move into full gcode programming and I am sure I will need some help. The only experience I have with gcodes is G00, G01, G02 and G03. That is all my machine was able to use. I have down loaded the beta of Mach2 which is limited to 1000 lines. Due to the limited nature of my gcode files I can't get any of them to run. Is it because there needs to be specific info in the first few lines i.e., absolute or incremental, toof offset, tool length comp, etc. As you can tell I have a lot of work to do but any help would be appreciated.

If some one has a sample hundred line file that I could run that would be appreciated and I could see how it is set up. TIA

G40-Cutter comp cancel
G41-Cutter comp left
G42-Cutter comp right
G50-Programming of absolute zero point
G90-Absolute programming
G96-Constant Surface Speed On "CSS"
G97-CSS Off
G92-Thread Cycle
G81-Drilling cycle
G80-Drilling cycle Off

These may help you a little bit but I can't guarentee it.

Thanks Machine1. I did forget to include it is a router ie a milling machine program. Oops, I almost forgot. I am doing wood so I won't need coolant. I hope to use that for some other feature.

Thanks again.

Here is the code for a plaque that I made for a friend with my homemade router, I created it from .dxf file from turbocad using Deskam 2000, hope it helps.

Thanks guys. I actually contacted Art and even though I had read the manual 3 times I didn't have my config set up properly. I have used simple gcodes for several yrs but with the addition of Mach2 I will also have to learn all the codes as well as the M codes.
