Thank you Gerry.

According to that Kellyware example you posted, someoneone loaded a DXF into Kcam and got a G-Code complete with Cutter Compensation!

I have never been able to use what K-Cam...

"D" as "tool radius compensation number".
If so, I would need to use G41 or G42 ?
What would a lind of code look like profiling with a Ø.25 Endmill?

Thank you for any direction or help.
...

Man! I would have never found this!

Thank You.

The manuel is 117 pages long, and I went through every page, but could not find this!

Thanks again.

Charlie

I loaded a DXF drawing and ask for a tool path (G-Code), I then stuck it into K-Cam to run the stepper Motors.

This is crazy!

I think bobcam is working in incremental, and I need an Absolute.

HEY ! ! ! !

I got it to work !

Let me do it a few hundred more times till I geter down pat.

Thanks Engine guy.

I load a Drawing,

Go to milling stock, select 2 axis milling, "profileing".

Go to geometry, re-select part.

Go to profiling, edit, pattern, select "offset left".

Go to tool, rough, select...

Ger21,
I re-wrote the program according to your suggestions. Nothing changes!

I did notice one thing, I would go a couple of lines father if I set the tool diameter at .100, same with the way you...

I have a very basic (3) axis Home Built Milling Machine.
I drive the stepper motors with K-Cam from a Desktop Computer.
K-Cam shows the out line of the part just fine, but when I put any diameter...

I wrote this code to cut an elipse out of 1/8" plate.

Sence I don't know how to use cutter comp, this is a tool path useing a 3/16 Dia. end mill.

After cutting the elipse, I want to make it...

I writ my own simple G-Code's to cut out simple parts. When cutting arcs (G02 and G03), why would I need to use I and J to define the center of radius instead of R?

They did not ask anything.

I have just purchased K-Cam, useing PayPal.

Do I get a disk in the mail, or is this a "download from the internet thing"?

Well, I got much father than you did. The program ran through line 6 and then stopped.

I will go back and check the radius points to 5 decimal places.

The last line of code takes the machine...

Why does this path stop with K-Cam, and not come back to origin?

I say it again,

"that is some beautiful work".

Thank You Leeuwinga

That is beautiful work, Leeuwinga.

I would like to see a close up picture of those Tender Trucks.

I have drawings, but they are not suitable for someone else to build from.

This is a semi scale model of the Virginian AE 2-10-10-2 Compound Mallet.

I burn Propane for fuel and run on 60 PSI...

Like this

I found that arc error, "Master 5" ignored it and cut it out anyway!

attached it the tool path in DFX

Thank you Andre'B, I have already cut this little fan out.

I wrote 2 programs to do it,

1. from the center of a disk, I drilled 5 .125 holes.

2. manually changed to a 1/16" end mill and used...

My CNC is a "Home Built" desk top design. I run the stepper drivers with a program called "Master 5", all I know is; "Master 5" can read G-Code.

I had to hunt and cordinate every single destany in...

The engine has a little fan to cool the head.

(Or you could take out your calculator and use the cartesian to polar coordinate conversion function to manually calculate the rotated numbers.)
...

ALLRIGHT, I did it !!!!

See the little fan? I cut that one out manually, about 10 years ago. I was running the engine fast one day and the little fan came apart!!!

So, I cut a 5 blade fan out...

Let's see if I can post a picture.

This is not a 3D surface. I cut this little 5 blade fan from a piece of sheet metal and then bent the blades to catch the air.

My real question is, is there a way to write the program for 1 blade...

There must be an easier way!!!!!!

Well, Mr Geof, That's a hell of a lot better than what I am trying to do, especially since I can not cut a thread to size.

Me and you gonna cut that thread some day. After I get back from...

So I write myself a program for milling 72 thread per inch. I will use a .25 Dia thread milling cutter. I want to mill a thread inside a .687 bore, the thread will go down about .06 in, and the...
