Kinda OT: Convert G code from incremental to absolute

[Thad]

I have some old programs (the files I sent you, Paul) that I would like to turn into MC9 files. They are standard G code .txt files. They "cut" a picture of Mickey Mouse, ET, and Calvin. (Paul's laser thread got me going on this.)

 

I tried to import them as ASCII files into MC, but since they're incremental values, I got a bunch of junk. I got these files about 8 years ago and have no idea what system they came from.

 

Is there an easy way to convert the values from incremental to absolute. Does anyone have any other suggestions? All I have are the .txt files (no CAD data).

Hi Thad,

I am not sure if I understand what you have, is it .txt with geometry? if it is old programs.

G00 X Y

G02 X Y

 

could you reverse post them into Mastercam ?, what is it RP"Post name".

 

I dont know, just one of these quick thoughts Thad

Thad could you use them as sub programs. There are programs out there called G-Code programs that will show you a g-code program like MCU but as stand alone programs.

I am thinking you use this to establish a origin of the part then you could call the program as a sub and make the shapes. If you have a problem with some of the code go into Cimco and just do the find replace and would make quick work of them. Like if they are G2 and need to be G02 then you just change them that easy. I am thinkign you could maybe write a script but thinking it would be someone what envovled. You can also take all of the X,Y coordinate and import them into EXCEL as a ASCII file and then dvide the colums and do a graph chart to see the shape also. Then you could save it as a BMP then if you have raster for Mastercam could import it and then do a toolpath in Mastercam and have it licked from there.

 

With the G-code programs that display what you have on the screen you could do a print screen then open paint then save it as a bmp also. The nthe same method with raster import into Mastercam good to go.

I knew I did not have a clue of what you were talking about

I just go back to my wire

All I have is a .txt file like this.

I want to be able to "reverse engineer" this back into a usable MC9 file. I could do a screen shot of the backplotted file (Metacut or other), but if that's the case, I might as well find my own pic somewhere on the net and use raster to vector. I don't want to do that. I want to use these files.

Lars, you're on the right track. Reverse posting sounds like a viable option.

I have a editor (PC-DNC) that has a inc/abs converter. I have not used it so I'm not sure how good it works. Feel free to e-mail me a file and I'll give it a go.

Ron,

 

Based on my last reply, do you have any other ideas? Thank you both for your replies.

 

Thad

[Thad]

Thanks Mark. Check your mail.

I think mcedit has that function also.

[Thad]

Matt,

 

It most certainly does!!!

 

Thanks!
