3d Model problem - ring around object

[tvannaman2000]

I've had some problems with STL files I've imported. After the final 3d toolpath is done, there is a ring around the model. In my sample above, you can see the ring around the border of the Alien 3d model. When looking at the 3d view, it looks the way it should look. The depth of where the cut is happening is at .2 inches.

Shape height: 1.3"
Base Height: 0.0

material setup: I've tried a bajillion different settings and it does not affect this issue, currently at .0648" gap above the model

I'ved tried a border vector for final toolpath, I've tried just the model. I've tried up to .05" boundary offset.

This happens on many STL models I import and combine with pocket toolpaths. I can send the .crv file if someone wants.

Any suggestions would be kindly appreciated.

Thanks.

Just a thought are you using a draft as I have seen this happen when I used it.

Not sure what you mean by "using a draft", but I have not carved it. I've imported it into a brand new CRV file and did the exact same steps and got it to look the way I want it so maybe a bug in vcarve or something else in the carve file is affecting it.

Thanks. I emailed it to you. Had to zip it to a .rar file because the .crv was too large for email at 14mb.

I'm having the same issue on Vcarve supplied 3d clipart and am using the double heart and rings. The line around the heart is related to the angle of the vbit and it's not getting close enough to the heart. Apparently, the clear-out section of the vcarve toolpath is not clearing out close enough to the 3d Object. I created a normal pocket toolpath around the heart with a .125" endmill and the ring disappears.

That sounds like the upper part of the v-bit would protrude into the 3D area whereas the straight up and down end-mill can cut right up to it. Would be interesting to try different diameter v-bits.

What is the Thickness of the material in which you are carving this sign from?
Reason for asking is you have a shape height of 1.3" noted

Also is the image you posted a completed carving?

So I am thinking that the model of the Alien is not properly placed within the material for carving therefore leaving a faint portion of material of the model at that surface.

Just my Thoughts!

Private message me!

Well that wasn't very helpful for the rest of us watching. I had no idea where or what the alien was from the OP first picture. I seen the circle but had no idea what it was suppose to look like without seeing the actual vcarve project file. Oh well...

Ezurick,
The main issue was that the new VCarve toolpath was used with the optional "Use Clearance tool" .
That created the "ring" or to be correct, the beveled edge to the head of the Alien.
The reason you did not "see" the Alien was because in the first Vcarve toolpath, meant to pocket out the first set of letters, the vector around the Aliens head was not also selected, so if reality the top of the face was cut away...
A few other small items but without seeing the file, my explanations would go on for a few pages..
My apologizes for not explaining bit I was later for work but I at least wanted people to know that the issues was resolved...

Happy to hear that the issue has bee resolved!

I had suspected it was something to do with the alien and/or carving there of.

It is always great to hear issue has been resolved!
