I have a cnc mill that I did a mach conversion on. I dont have a clue of how to program anything..sad but tru. Has anyone done a mini logo ? I made a couple pieces and would love to mill the logo into them. Thanks Jim

Dawned on me that you may need the Mini dxf in case you want to adjust the parameters and program to your specifications.
The dxf was drawn using AutoCadLT version 2008. Copied a picture of the logo into AutoCad and used the connect the dots process to produce the file. The result would not fool a "Mini," expert, but should be good enough for one-off hobby work.

Here is a dxf based on backplotting the gcode.

Rich, not familiar with backplotting. How do you do that.

Bob,
The gcode for a lathe or mill is manipulated back into a form of a dxf file. If you look at version 12 dxf file with notepad
you will see data for every vector / direction and length . Backplotting is the reverse. A friend wrote a program that works fantastic so i keep testing it. What you get in the backplotted dxf is all the pathing and the pathing are placed on diffferent layers and color coded. Very easy to compare the original dxf to the gcode generated. Unforetunately
he will not share it with the community. NCPLOT is a program that will backplot but it's like $400.

Thanks. Will give it a shot! Just got my mill's computer back.Was stuck on power save mode. Grrrr.

Hey, It worked..Not that I didnt think your code would work but just the fact that I was able to copy it and transfere it to my mill and get it to work! yep I know its easy for you guys but I cant do anything with cad.. Sucks.I am struggling trying to learn it.Self teach. No cnc experience. Never touched one till I got this mill. Just want to play. lol..
Here it is. I used a center drill to do it.Dont have anything real small so this was the chosen one.lol..I ran black magic marker over it to highlight it . It looked better before.

A big thanks! It is nice to see the mill do something. All I do is mess with the wizards in mach..

thanks tweakie.
Been a long road. I started this undertaking(the cnc project) probably 4 years ago. then took a new job that is 100% travel so the learning curve came to a stop. Everytime I was home for a bit I would start at it again.basicly 2 steps forward and 3 back.lolOverwelmed with the amount of stuff I needed to learn.
here is my finished project...(http://img.photobucket.com/albums/v24/ikimjing/1327000111.jpg)

I am VERY thankful for ALL the help I have got from people on the net. I would have gave up years ago. Thanks again to everyone!
