Problems with final product

Post by tonybell96 »

Hello,

I am rather new to Aspire, but have an interesting, yet frustrating, problem.

I purchased the attached model and ran it on a piece of 3/4 in walnut (Love working with walnut) using a 1/8 in ballnose.

In the center of the ship there is a triangle piece that did not cut, there is also a "line" that stretches out on both sides of the triangle. I have attached screenshots of my setup, but when I preview the file it looks perfectly fine.

Thanks in advance!
Tony

Perhaps your Z-zero was "off" and left that bit of material behind when you carved the project. Hard to tell from the tiny photo. Try running it again, but make certain your Z-zero is correctly set. Maybe run the project on cheap wood or MDF for the test before running on more Walnut.

Another thing some folks like to do is to set the model slightly below the top surface of the material (to assure no "flat spots" are left uncarved). This is done in your Material Setup menu (Gap Above Model setting).

Your z setting is set too high, lower it to 1 losing step and hitting your upper z limit

Hmmm. Possibly. I understood the Shark HD had 7" of Z, so I wouldn't think the 3" Home Position setting he has would normally be a problem. (Unless his spoilboard is unusually thick and "wasting" a lot of Z capacity.)

In any case, I agree it's likely just a z-zero issue as I stated above.

The actual Z clearance on that machine is closer to 5.5 inches minus 1 to 2 inches for the bit extension, and the 3" home, and a .75" spoil board.
Yup, that's real close to end of Z travel.

The model you cut appears to be inverted ( the high parts are low and the low parts are high)
If you are setting Z to jump clamps your setting makes sense for the rapid move setting.
I suspect the job material thickness and model height are the problem with the flat spots in the finished model......the inverted appearance...I am unsure what you did to achieve that

Might be an optical illusion. I don't think the model is inverted.

I have carved that model quite a few times - -if you look at the handle of the sword (bottom of the pic) you will note it is concave vice convex

The waves are convex vice concave.

I must need new glasses. I'm still not seeing that. :shock:

Look at the shadow from the shield... It's carved right. Just an optical illusion.
I can't see the "triangle" referenced in the OP though. Looks like it all cut but hard to tell from such a small image capture.

I see it now, it's on the cut part, not the model....
Is that triangle flat? IE, is it the top of the board you used?
Probably help if you post the toolpaths used.

Here is my toolpath... again any help would be great as the "line" is still there.

That's not the toolpaths, just the setup.
post the .crv3d file.

In the last screen shot it shows 0.0003 material on top.
that number should be 0.00000 or else you will be left with some material on top......like the triangle you refer to.
Are you cutting this model to make a mold?

Don't think that's right Pete, by setting a gap above the model it forces the model further into the material as far as I know. People use this when the material may not be completely flat to ensure that the highest parts of the model cut & are not left unmachined due to a low spot in the material
