Inside offset problem with slot less than 2x cutter diameter
« on: October 24, 2008, 09:54:24 AM »
I can't get Lcam to do an inside offset in a slot that i need to cut that is less than twice the cutter diameter.

Lets say for instance I need a slot milled 5 inches long and .100 wide. The mill I wish to use is .060.

The slot is clearly wide enough to use a .060 cutter but I can't get Lcam to do an inside offset for anything less than twice the cutter diam. When I hit the offset button I get no "visible" offset but I do get a new rapid line. Is the offset actually produced and I just cant see it on the screen maybe? I haven't actually tried running the code yet because I don't want to waste material if I don't have to.

Thanks

Ryan

Hi Ryan,

Can you post your dxf for us to check out?

Ok, thanks. I had a look t it and I'm not having any issues using a .062 cutter. Let me ask you, are you zooming in when offsetting? I've noticed that the closer you are to the chain being offsetted, the lessw problems occur but frankly on this part, I could have everything in view and it still offset correctly.

Also, did you use the "clean" button before trying to offset?

I'm uploading a few pics for you to show that it can be done. May I ask also what version you're running?

From what I remember I didn't zoom on that area before offsetting. I think I did try the clean function though. I will try again and see if I can make it work as it is clearly possible.

Version 3.00.2

Zooming was the trick!!!

I got it to work by just zooming and doing nothing else. I did have to zoom in on it quite a bit. So much so that part of the object I was offsetting was outside the window. It still worked none the less.

Thanks budman!

You're very welcome, glad it's working for you.  :)

Just a side note, always use the clean button when you first import a dxf. It has saved me from many "unexplained" occurances -  :D
