After cleaning, select roughing tool, go to the bottom box and give a name to it , then select one of the numbered tool from the pulldown
click save. Select it, then when you go to the finishing tool use the pulldown and you should see the tool you just saved.

I said this would be fun!

Play around with the paramters some and see what lazcam shows.
Step: .050, .1, .20, .005
margin: use .1, then try decreasing it, like .010
Finish: .001, .002

I got the unrecoverable error to. In the tool window change the angle to something like .1 deg seems if it's to small things crash.

I don't care much about the tool parameters, to cut this handle ( small one anyway) you would need to use a "point tool ".

" I said this would be fun!"
Oh it is............but it was much more fun when I had HAIR !
Thanks RICH,

EVERY TIME now....tried all I know to try...many combos  .
Thanks RICH,
done

RC,
Happy your foolin with the file, you fell into my spiders web. You just identified one of the frustrating parts.
So I was going to do some quick guide on inputs. I won't get into changing start point,
the layers and all the other side bar stuff. I am trying to keep things simple. 


My thinking on this goes like this:
I should be able to create a point tool but shouldn't have some value which would may cause dividing by  or allmost"o".

Why this one is hard, is that there is no way you can cut this with one tool unless it's a point. Thats why the
inside corners have that .004" radius curve between the balls. That curve must be large enough for a tool to be able
to get in there and cut it and also do rough cleanout cuts. So it could be a good drawing, clean and covert well, but now you got to put some thought into how it's going to be cut. With some profiles i would guess it may be easier to use / compose it out of the wizards. Most users will un-thinkingly just assume what's imported can be generated with no
thinking around the cutting. No program is that smart.
Let me know how it looks in MACH.

RC,
Reboot your pc. I have found if you continue when you get that message your going to the black hole. Even if you go out of lazycam and MACH and come back, go to some other program and it works, if you go back into MACH or Lazycam
your in for the message again. I tried it until I locked the PC up. Just reboot and start clean, but take a look at the tool and also parameter's when you go back in. One or a combination of them is the culprit.
RICH

I wish I could get it TO Mach. I get the error when I hit the Create Profiles button.
RC

Just got your BOOT post.
Will try that, just before I boot it out the door.
RC

Well the cord was too short...didn't make it through the door.
Error every time still.
RICH, could you post the .lCam file of the part ?
Thanks,
RC

I just got that message also. Need to reboot. Back in about 5 minutes.
RICH

.lcam ?? where, what , Do mean the file which is posted by lazcam into MACH?
If that is the case the first one with code errors is attached. All of the files are included and noted in the
THREEBALLS4TO4D.txt file posted

That error message must be catchy. Got it again. May be that the step and margin in the parameters can't be the same.
RICH

When ready to post code, save it here.
Then send.
Thanks,
RC
