A test of How did they do that

[ohiolyons]

So I was watchin a FB post from Quint Signs, ( https://fb.watch/7aJY4IaIVt/ ). Watch the video before you try to solve the problem.

They appear to be doing a Profile toolpath on lettering with a model underneath a texture.

So I used a texture from clipart. Added text and converted to vectors.
I did a Roughing and Finish toolpath on the texture only, excluding the text.
I then did a Profile toolpath on the text vectors, zero depth, projected on 3d model.

It works partially, but not like the video.
They do use Aspire.
I have posted a FB comment on how do you do this and they haven't responded yet.

Don't use my file maybe I approached it the wrong way????

Project to 3D doesn't make that surface the bottom of the cut but rather the top of the cut, How about a profile toolpath cutting 0.001 inches (0.025 mm) deep—basically no appreciable depth of cut—projected to the 3D?

[ohiolyons]

0.001 worked better, but still not the same as on the video.

I'll update if they respond to my FB comment.

Or even zero depth (zero start depth, zero depth of cut). You don't need any depth to run a profile pass.

[adze_cnc]

I always worry about the potential for divide by zero errors.

[ohiolyons]

Or even zero depth (zero start depth, zero depth of cut). You don't need any depth to run a profile pass.

I already did that.

How is it coming out different?

[Beltramidave]

Looking through the Program Options and came across this. Does this effect this question...

[ohiolyons]

Turns out
start depth 0.000 cut depth 0.000 project on 3d model
and
start depth 0.000 cut depth 0.001 project on 3d model
yield very similar results

The verticals on the H are not behaving as the video, the vertical on the left side of the E is.

the up and down movement all the curved parts are incorrect too.

In the video the up and down toolpath on the left hand side of E is the way all letters should be.

And the winner is

DROP TOOL no

Thanks for all who helped.

And the winner is

DROP TOOL no

Thanks for all who helped.

Can you explain this more, please??

[ohiolyons]

EDIT tab, scroll down to and select Options, then scroll DropTool Under the Toolpaths Settings subheading.

Mine was set to Yes and changed to No

The result now looks like the motion in the video.

From the manual

[ohiolyons]

It is actually working exactly opposite of what the manual states with my limited understanding.

I think I know what the toolpath means, but what is the project. Is it the model? How does the project and model differ?

I just know it looks like the video when you set it to No.

[adze_cnc]

"Project" as a verb not a noun.

When projecting a toolpath on the model, drop the tool on the surface rather than project.

would better be written as:

When projecting a toolpath on the model, drop the tool on the surface rather than project the tool to the surface.

Even that is confusing without an understanding of what the real difference between "drop" and "project" is. i.e. in one case you are "projecting by dropping" and in the other you are "projecting by projecting".

[scottp55]

Still confusing to me, but saved that manual clip to desktop so I can play with it and preview the cuts.
Might come in handy, but never would have run across it myself!
Thanks!!
