Anyone have GCode or DXF for something similar to my attached image? Or if at all possible willing to turn this into a Gcode/DXF?
-
Hi
Are you looking to engrave this and what size are you looking for
-
Afternoon
I'm actually looking to cut it out on a plasma cutter with a 24inch Diameter roughly
-
Hi here is an NC file to cut this image some detail is missing due to the original image size and properly the software i used to convert to DXF
-
Thanks!
-
Nice, Steve, can you put up the dxf so it can be used to do a vcarving?

hi Andrew
i think your dragon is way cool i am new to this .
the down load of the dragon gives x 630.8750 then y axis is 611.2970 if did my math right mm to standard y axis is just over 24 in.
i have a diy cnc router x74.5 y 23.5in 611.2970 mm is hitting limit SW y + i tried to look this up in the manual and i remember resizeing or scalling somthing like that except i cant find what im looking for to reduce the size of your dragon by 10 % im a newbie i am not sure if i am useing the right word i really want to make your dragon but more important to me to learn how to make my own stuff i dont care what example i work on i just need to know figure this out. is resizeing the right word was going to run dragon file with z axis -0.030 in mdf see how it looks
Can you get me going in the right direction i have been studying gcodes and m codes is plain to see i havent study enough
thank you muke

On the main screen you have scale entries next to the position dro,s click one of them and enter 0.9 and hit enter do this on both X & Y axis.

hey Graham
i did what you said at first it was doing
then my cnc kept going _x _x untill it hit my limits about 250mm -x
mike
-
hey graham it was like i changed the off sets in the middle of the file
i have rewind several times to set z plunge bepth at the first of the file i did the by zero my z axis dro not by changing g codes .

THere IS a problem with scale. It sometimes changes in the middle of the program run.
Just a thought, (;-)TP
-
I am glade i i put 2x 8 ft sheet of mdf and said im just going to practise on this half sheet
until it is all cut to pieces . because it is starting to look like junk.
mikee
-
not very good on g codes yet what would i be looking for and can i fix this
-
i have not change anything on my cnc beside raised z axis
-
scale on program run is the same as when i set it
-
scale 0.9000 same as when i set it
-
started to read lines g code the x is to the minus side every line 2 to 4every line mike
-
sorry 2 to 4 mm every line toward _ x axis
-
well if anybody can mess things up it me from tool path to mdi to program run the off set is different in every screen
mikee

ran file again this time i jogged to where i wanted to cut dragon. zero cnc (not mach cords)
did air cut everything went fine i got the od first pass went ok second pass x axis went about 50mm -x feed stop once again all the screens that display are different from one another. offset screen is good program run and mdi is tool path screens not right and oposite of each other noticed both times machine cordance change again. only on x axis Scale is where i set 0.9000.

Download this program and run the code through it with the scale set at 0.9.

Hey Graham
Ran file at 0.3000 scale ran fine.
I didn't do anyting different except wanting to save some mdf so scale down to 0.3000
I will download what u sent to me. Will not be able to run what you sent me till tomorrow.
Do you have any thoughts on what i am doing wrong?
Thank you for help and all the help i have received from everyone in here

I ran dragon at 0.6000 scale
once again i dont know what to call this problem but offset changed just the x axis.
this G code file of this dragon is very nice.
i will start a topic in g code discussions. thank you graham.
idea on what i am doing wrong
-
Mikee,
I converted the Gcode to a dxf file. The dragon basically fits within a diameter of 1.
Unfortunately the dxf file is extrermely large like 10 megs as there are 64000 lines which make up the piece and can't post it.
Frankly for engraving it leaves something to be desired as the image is not that good. If it was done manualy i would guess the number of entities would be say 900 and the code would be just a fraction of what your using and the image would be satisfactory.

It was meant for a Plasma Cutter, not engraving. Considering the image I provided I don't think it came out so bad :)

Thank you
It was a challenge to get this far and i learned how to scale.
I also had to brush up on my metric system.
I still dont know why my offset change.
I also have file cure is a help to.
I think the Dragon was way cool.
