Are you guy's sure your not screwing with the new guy!  hhahahahh!

First of all i used the DOC's file to get the part ready to cut. Everything went perfect and was very easy to do.

I spent hours trying to replicate what was done and   IM A FAILURE!! I cannot figure out what is different between the Doc's and mine. Here is what i tried. What did I miss? Is there something in the setup that i need to change? Why does it work on doc's computer and not mine?

Load AirCleaner4Test.DXF
Turn Rapids off
Turn Leads off
Move Chain#0 to new layer #3
Move Chain#2 to new layer #4
Move Chain#4 to layer#4
Move Chain#1 to new layer#5
Select layer#5
Click pocket tab
Click spiral, ccw, in-out, left
Click tool, 1/4, step 40, finish .048
Click create islands
click create pocket
Failure
Move layer #5 under layer Visible
click chain#11
click pocket
Failure

you aint dead yet, here is another pile of crap. heheheh!

The first thing i do after loading a file into l-cam is to turn leds off then turn the rapids off before doing anything. maybe that might be causing you a little snag.

keep in touch were all pulling for you.

I am going to try to do what you described here. I never would have figured out this type of stuff. This is exactly what i need in the way of helping me and not doing it for me. I really appreciate your patiance and if i ever figure this stuff out, I will pay it forward for sure!!

You'r killing me!!

How exactly did you do that. I scaled up 20X and created a tool 20X and tried to do exactly what is in the previous post and no luck. Still wants to cut the entire oval out. Yes i checked "create islands"  Is there something else in the setup stuff i need to change?

Hi Doc!

Thats some nice work there but....  Its backward. Take a look at the photo of the air cleaner about 4 posts ago. The part you cut was supposd to be the part that sticks up.

Sorry if i wasted some of your time.

OK NOW I got ya, I'll work on it at that level then. I might be able to get it working now that I know the real scale of things.

(;-) TP

Keep track of what you do. The only reason for making this thing was to learn how to use LC and Mach3.

Thanks for all the help thus far!!

Steve this part is TINY is it to scale??? IF so you will have to work with extremly small bits to make it work.

UNLESS that is the idea (;-) TP

This part is huge compared to some things i have made. I have a steam/air engine that has a .0625 bore and stroke and a .250 flywheel.

The first picture is the air cleaner i am trying to replicate. The second is the engine it has to fit. If the size is .950 wide and 1.950 long then it is to scale. The plan is to cut it out with a .016 end mill. This is the second project i am attempting to do with LC. The first went well but this one is giving some trouble but that's how you learn.

I tried to pocket the area but it did not leave the ribs as islands. It pocketed the entire oval. The tool being .016 and an overlap of .007 I thought would do the trick. Then i tried to do an offset around all the ribs in the center and it would only do a few ribs and stop. The offset would not go all the way around all the ribs in the center cluster. It is pretty complex but if you folks think it is possible, i will keep at it!

Now see if you can pocket the inside of the large oval and leave all those ribs. I think that large cluster in the center is too complicated. LC wants to machine the entire center removing all the ribs.

Not sure what you are doing to combine them. I used a line connect tolerance of .001"

(;-) TP

That was it!!  I set mine to .001 also and BOOM! it worked!

Thank you!! Thank you!!  Thank you!!  Thank you!!

I have tried alot of things described above. No matter what i click that "rib" seems to always be part of the larger oval. All i want to do is pocket inside the big oval .032 deep and everything in there will be islands. Then i need to cut the outer oval to complete the part.

Here is the file

Is it possible to take 4 entities out of a chain and create a new chain of those 4 entities. In the uploaded photo there is a thin strip that needs to be broken away from the outer chain.

Can this be done?
