what budman said is good .  v12 basically used here. my example was how i managed your drawing. l-cam does not like arcs on small parts. try drawing on many layers and scaled up, this helps.
avoid using offsets on pockets if you can, it might generate oversize code. l-cam has a lot of power ,but it does goofy stuff. when you draw big to go small it helps alot. it saves on crop circles too.
lately i have got in the habit of big drawing and using the scale feature of mach3 wich works really good.

Hi Steve
here is a pic of my loading setup. this pretty much gets most of my stuff.
this is going to be a step by step of what i did to your dxf to make that l-cam file.
1.import file
2.turn off leads
3.turn off rapids
4.scale to check for X dimension , i wright down 1.950,close scale,make sure origin stays lower left
5.leave large outside chain in original layer,move second largest oval chain to next new layer
6.move big curly chain to next new layer
7.move top small chain to next new layer
8.move bottom small chain to same layer as top small chain
9.open scale and set X to 31.200 wich is 16 to 1
10.after scaling highlight each layer to make sure they are still where you put them
11.open scale again and make sure it set to 31.200, if it did not repeat steps 9,10,11
12.hit optomize once
13.highlight each chain and move lead arrows to middle of the flatest and longest line
14.check each chain and make sure your leads did not move
15.hit optomize again
16.save as your master l-cam
17.close l-cam
18.restart l-cam and load you l-cam file turn off leads and rapids. you should be ready to go.

Hi Steve

you aint dead yet, here is another pile of crap. heheheh!
you said you are going to use a .016 cutter ,so i guess the real number is .015625 . at 16 to 1 that moves up to .250 . the l-cam i gave you was allready pumped up 16 t0 1 ,your orignal dxf imported showed X as 1.950 ,bumped to 16 to 1 made X 31.200 .
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. those two items mess the chains real bad.you dont need them until the end.
i made two g-codes for you that cut .016 deep so if you want to try to run them make sure to edit the feed and speeds.these  tool paths are both generated off the l-cam file i gave you set at 16 to 1 or 31.200 scale. air-poc1 after pocket path generation
was scaled back to 1.950 then you delete all layers except the pocket. then optimize, then i moved origin to center.you do origin the way you want. selected tool for the layer then posted code.this code works with mach3 X&Y scale set 1.000 .
air-poc2 was generated 31.200 and not scaled down. before loading into mach3 set scale X&Y to .0625 wich is 1 to 16 .when you check both files toolpath after loading you will see they are the same. this just shows differant ways to do the same thing.

keep in touch were all pulling for you.

i did not target your part to cut it out. just trying to show you a possible solution to using l-cam. only wasted 5 min anyway.
that is a good l-cam file i gave you back ,you should be able to do alot of damage with it.

hi steve

here is a l-cam file and a pic. i scaled you up 16 to 1 in l-cam and and moved chains to new layers. used a scaled up tool wich comes out to .250
it generated paths ok. lcam does not like small stuff, so go big to go small. you have two options from here after generating paths. export the code scaled up and set the scale in mach3.or scale lcam back down after pathing then generate code.

SScnc

 to jump your thread for a moment. do you have a good source for your cast tool and jig plate material . is their a chance for your supplier info.

thanks bill
