G Code for Chess piece

feed rate changes are typed in as
G01 F10 (text goes in parentheses and G01 and F# alone on line normally )
once you set a speed it stays until you change it, there is no need for it on every line
G0 ( went to max speed)
G01 f5 ( now feed rate slower )
the G01 and F# normally are on the same line together then the move is placed under it
here is an example of moving down z cutting grooves...

X.4 (clears material)
z-2.0 (goes to grove location)
G01 F2 (sets slow plunge rate )
x.28 (plunges in groove )
G0 ( changes speed )
x.4 (retracts to safe distance )
z-2.2 (moves to next location in Z for groove )
G01 F2 (sets slow plunge rate )
x.28 (plunges in groove )
G0 ( changes speed )
x.4 (retracts to safe distance )
z-2.4 (moves to next location in Z for groove )
G01 F2 (sets slow plunge rate )
x.28 (plunges in groove )
G0 ( changes speed )
x.4 (retracts to safe distance )

I hope that helps
Steve

it was just an example of how the code would be typed in. I wasn't really paying attention to feeds and speeds or dimensions.
I was just changing speeds and locations as an example of how I have learned to enter it.

what is your max volatility set to, it seemed really slow on the G0 moves in the video?
G0 should move at the highest speed the axis will move without missing steps.

I was at F10 and spindle speed I really don't just guess at it to get a smooth cut on the acrylic
can't cut to fast or it chips and the heat will separate the glue from the brass tubing inside.
I finally got a mark on my speed dial to where it cuts great and don't have to do a lot of wet sanding too
get that nice glassy shine....

Well Here is the latest video of the Gcode for my pen and pencils.
I have totally rewritten the Gcode for it.. The video is a piece of dowel that
I had. This is just a test cut to see if the Gcode would work, so for it's a go.
Now I need to do it with a piece of acrylic.. I want to thank everyone for
the help, I finally figured out the code for this, dang my head hurts.. Oh yeah
if anyone wants this code let me know and I will upload it'''
Thanks Again
Glen

Ok here is the final video of the pen/pencil GCode in action
I found a piece of piano wood and cut in down to 5/8" X 5/8" X 1 1/4"
Then turned it to size for a pen/pencil......
If you need pics of the piece I will upload it....
