having problems with ngc format

[servoencoder]

My current dellema is emc won't accept the nc file from kcam, unless there is some 2.5d dxf -> ngc converter that i am not aware of (been searching forever on dialup)

second choice, would there be a way to manually change kcams nc -> emc ngc format - not very fimiliar with the ngc file structure (howto guide?)

with this problem out of the way and next paycheck construction will start

Can you post a sample of the file? Have you tried to load and run in simulation mode?

Its a a top half of an airfoil, everytrhing is fine and working in kcam but, if there is a way to use emc it would allow me to use servo motors.

A tutorial on ngc formatting would probably be my best bet

Thanks

all you have to do is change [] to () and get rid of the % at the beginning of the file and add a feed rate where you want to do a feed move (G01, G02,G03 etc...). I changed these things and the program loaded fine in Axis.
Read up on G code. It's a very simple format.

Might I suggest that If your KCam output allows you to state a line number to increment by, use it. This will give you some wiggle room for adding gcode. Increment by 10 and you get N010, N020, N030, etc. Handy for adding a feedrate using "F" like this:

N015 F15.0

You may also want to look for a post processor to take a KCam gcode file and remove the stuff that is not needed and convert the braces to parens.

Not sure if anyone has a small script of program that does it. However, you can use a text editor like notepad and do a Replace to achieve the same thing.

doing pretty much what dan suggested...
although the first 200 lines or so are the same position
ie N127 G01 X0.478 Y3.68 Z4.431

Top notch help @ cnczone, thanks, saved a bunch of time and head scratching

[kiwichris]

Is it just me, or are you rapid moves 'under' the top of your material? Or am I reading the image incorrectly?

Interesting g-code though, was it created from a point cloud, or 3d Cad?

Cheers, Me.

[samco]

I was trying not to think about it.. but yes - that is what it looks like to me.

[servoencoder]

yes the rapids are under the material, thats just how kcam converted them from turbocad (i dunno).

I just manually change them in kcam to go above the workpiece

not sure how else to do it?

Aware of any converter RS274X to RS274D?
because it is tedious to be editing the files
Gerber to work with emc ... I am using Sprint Layout

[Zig]

274x and 274D are both valid Gerber formats. The only difference is that 274D requires a separate apperture definiton file whereas 274X contains imbeded apperture information.

If on the other hand You want to generate outline milling information from gerber then You need a separate piece of software.

There are many such applications and a search in this forum ought to bring up some references.
