I think I've got it now, took a while to see where to set everything and move entities to a new layer, set the depth and offsets but I think I am ready to make some acrylic snow as a test cut in plexiglass scrap.

Attached are my LC file and tap file.

your doing better. but you have to redo it.when you offset a chain you have to remove the original chain.you left all of you original chains and when l-cam did your code it wrote them into
the tap file.l-cam will take everything that it can find active and write code for it.so you have to delete or disable original chains.later tonight or tomorrow i will do your dxf with a 3/16 end mill
the way i think you should cut it out.and you can use it for a comparison.you are catching on pretty fast,just keep pounding on it.

Bill,

I just tried cutting and my 1/2" dia pockets are more like 5/8" Guess I need to go back to the original dxf and start over, but it's progress. I do use inside offset for the pockets, slot and holes and outside for the outer perimiter correct?

Kristin

Kristin

you did not delete the original chain that you used to make the offset.

bill

I get that part, going to start from scratch, I could not figure out what was what at this point so I'll start fresh and move layers offset then delete the original chains Think I'll write down all the numbers first so I can keep it straight.

Kristin

Kristin, just take note that when you pocket or offset an item, as soon as you click that button, the original line that was offset or pocketed, will turn red and then all you have to do is hit the "rem. objects" button and it will disappear - 

Really not getting there, anybody with a clear step by step moving layers, offseting and deleting originals explantion, it seems I select the wrong thing to delete. Going to start again real simple with a single hole and a single recess, way too hot today again.

Kristin

Dave,

I have tried that, just seem to be getting nowhere, I know I said I didn't want pre-made code but if you could just do a .191 dia through hole .25 deep and a 1/2" dia around that .125" deep at least I could compare the code. Oh I am using a 3/16 end mill so it has to be offset from what I can figure .0995" or is that a negative number too? I keep getting too big a circle with everything I try. I would think the offsets for this would be inside which I what I have been using, well another several hours wasted and I seem to be getting nowhere fast.

Kristin

Ok, I did one for you with a .030 Z clearance height and each pass is only .030 as well. The plunge feed is 1 and the feedrate is 10 but change it if you like, of course.

  Let me know how it goes for you, ok?

Dave How very interesting the code now reads :

N55 G1  Z-0.0300  F1.00
N60 G2  I-0.0021  J0.0000  F10.00 N65 G0  Z0.1000
N70 G1  Z-0.0600  F1.00
N75 G2  I-0.0021  J0.0000  F10.00

Not the -0.0955 that my lazy came generated???

ODD indeed....
