hey,
i need gcode and sketch for easy logo at size 90x50x15
onCNC MILL .
-
Post a dxf of the logo you require (highest resolution would be best).

I dont know how.
i just need it for class. it can be any logo.
there are two requaiment:
1: at least 2 arc with i and j
2: the size 90X50X15
-
You have to do some of the work yourself - I have no intention of doing it all.
1) Find (or design) a logo of the correct size, containing the required arcs (.bmp would be OK but .dxf preferred).
2) Use the full reply and additional options tabs to post your logo here.
I will convert it into a dxf and produce an engraving toolpath Gcode then post both here for you.

i will tanks you

is its ok ?

Sorry to say but that would not be ideal.
It has a background size of 23.8 x 13.2 mm and when scaled up to the required 90 x 50 mm has such poor resolution that it would be unlikely to yield any i and j arcs.
Try to find something of the correct size and of a good resolution.
(You could use a CAD software to create a border 90 x 50 mm then perhaps insert some text with a font that contains arcs - the easiest solution perhaps).

This is an example of what I think you want to achieve...
Initially a logo is found which is close to the required size (internet search).
The logo is then converted to a .dxf and scaled to the desired size (cad software).
A Gcode toolpath is generated from the .dxf (cam software).

Tweakie, I came across this and hope you could point me in a good direction. I have made my 3 axis cnc router from scratch and very happy with the results so far I have used the done some pocketing and cut files I have downloaded. Now I want to make a drink coaster with Alabama football logo on it. I think this should be a simple enough project, any suggestion on how you would go about this?

It's a process as I outlined in my last post.
Attached is a .png graphic which was converted to a .dxf and then an engraving toolpath (Gcode) created using Vectric.

Thanks Tweakie, that is awesome. I will try to cut it tonight. I see you used Vectric to create it, do you know of a good program to do this that not so pricey?

Perhaps check out the ScorchWorks website http://www.scorchworks.com/Blog/category/cnc/

Tweakie, I cut the logo you made for me and loved it except It is the mirror image when I cut it. I verified my axis are moving in the correct direction according to Mach3 keyboards commands. I tried the G68 command and not sure I fully understands how it works. Any suggestions you have would me greatly appreciated. Oh and till now I had now idea that metric g-code would run on my machine.
Thanks Hawk.

I am pleased for you.
If the Gcode I posted produces a mirror image then your axis is reversed – this can be corrected by changing the Direction Low Active state of the axis in Config / Ports & Pins / Motor Outputs.
The direction of an axis movement in relation to a key press can be changed by Config / System Hotkeys / Jog Hotkeys.
The point to remember about all this is that true axis movement is the direction the cutting tool moves in relation to the work piece rather than the actual direction of movement of the machine slides.
