Model Carving too deep

Post by Leo »

I do not want to upload the file with the models in it.

The stars are too deep.
I want the stars to be flush to the surface like the anchor is.

If I shut off the anchor models the stars will be flush - but I want both to be flush so both Anchor and Stars need to be on.
Hmmm - I may be answering this myself???

Any thoughts - suggestions?
I have tried as much as I can think of.

Could you post an image of the “3D Finish Stars” toolpath specs?

Just off the top of my head. . . you may need to create a base for the stars to sit on top of to raise them. Something that is flush with the background.

Have you tried putting them on different levels or adding base height?
To be honest I am not that good when it comes to 3D modelling. When I have had this sort of problem in the past I have got around it by turning models on & off & then machining them separately :lol: :lol:
It has worked for me but not the best use of the software :oops:

Adding a base height to the stars should solve the problem.

I tried changing base height and shape height with many different settings.

At some trials I also noticed that the base and shape heights got changed to number that I did not set.

Seems like Vectric takes all active models as one entity. When in the SET window to adjust depth of model I cannot isolate the stars from the anchor.

Martin, yes, that does seem to be the work around.

I have never used LEVELS - maybe that is the answer.
Do you have a brief explanation of that?

Here are the 3D Anchor and Star tool paths

I tried LEVELS

Stars on Level 1
Anchors on Level 2

Did not fix the issue

Are you by chance bundling the stars with your V-carved letters...just a "what if".

No - the stars are a 3D finish toolpath on a 3D model using a 3D finish toolpath

The text is not modeled and is a Vcarve text on vectors

I'm experiencing the same issue with a project I'm working on. Tried different levels as well as different base heights for the various 3d models that make up the project. But when it comes to creating the toolpath it groups all the models to same height as the model that has the greatest height. I'm using version 10.515 of Aspire. Defiantly puzzled by this.

Leo, could it be that you don't use a Roughing toolpath? I've had a dissimilar problem with Vcarve Pro when I tried to eliminate my Roughing toolpath on a project.

I was in a hurry so didn't follow up on it, but at the time I was wondering if this was a "quirk" in version 11.

Perhaps "something" in the Roughing toolpath gets referenced in the Finish toolpath?

Had a quick play today Leo, try adding a small negative base height to the stars, it seemed to work with the 2 models I tried it with from the clipart :lol: :lol:
A positive base height seemed to drive the shallower model even deeper which was why I tried a negative. It was just a very quick test but seemed to look ok. Maybe try a negative number so the 2 models equal the same thickness if that makes sense :lol: :lol:

I can't really add much when it comes to using levels, I have not used them much myself, just when trying to get components to look right when building things up :lol: :lol:

I have tried negative base and positive base. I also tried merge, subtract, up, down. Yes things did make differences, but I could never get a combination to work out.

There are a lot of different settings and combination of settings.

It just seems that when all models are active, it cannot be done.

One thing I didn't think of was zero plane(s).
I will play around with that today.

One thing to note.
The models are not clipart
I created the models.

The times when I've had problems like this, it was because one of the components (not the star) went below the modeling plane somehow. This caused alignment problems with all the other components. You might check the non-star components to make sure nothing is dipping into negative territory.

Steve, I am not sure what you are referring to.

So this is where I am currently
too deep-11.jpg
I added a zero plane on each level.
Calculating to the level made the 3D work the entire material - not good - not good at all

I then used selected vector - but the stars were still too deep.

Scratching my head - I tried base height again.
-.125 base on the stars only
Recalculated - reset preview - run all tools
result = stars flush + anchor too deep

+.125 base on stars only
Recalculated - reset preview - run all tools
result = stars WAY WAY too deep + anchor flush

Hmmm - compromise?

-.062 base on the stars only
Recalculated - reset preview - run all tools
result = stars flush + anchor kinda flush

I think maybe adding levels and zero plane helped
I am not really sure

I have spent many hours on this.
I cannot charge the customer for my learning.

It was an interesting challange.

Take away - use Levels - use Zero Planes.

Thank you all for the input, suggestions and helps.
