New Scanner-Is this right??

[c6craig]

Hi all,

I ran my first scan with the probe tonight and I'm not too sure if my results are typical. Maybe someone with more experience can tell me if this is what I can expect?

The scan was of a Woodcraft knife blank. I specifically wanted to scan something metal to see if it scratched the surface.

What suprised me...and what I am wondering if is normal...when the probe moved along the knife surface, I expected more of a dragging motion. This was more of a sewing machine style rapid paced tapping. As a result, instead of the smooth surface I expected, I ended up with this.

Any advice?? Am I doing something wrong or is this typical?

Thanks in advance,
Craig

It should be smooth, the last time I had a problem like that was the item was not mounted tight to the sled.

That's how some of my knife scans came out too. I used blur or degauss or something in the pattern editor to smooth them out.
By the way, thanks for the pattern, would you mind sharing any others you do, I've been trying to get a good wooden knife collection going...
Thanks again!

Try taking a small mirror or piece of glass make sure and clean it good then scan it. It can be a really small piece so the scan wont take long (2 or 3 inches) be sure when you scan you are picking normal or best and the scan should come out smooth on top. If it does not post the results. Let us know how it comes out any how.

Thanks, I will try the mirror trick tonight. I have the machine doing a 4 hour scan now on a different knife blank to see if it does the same thing. I really made sure this one was solidly attached to the sled and not moving in any way. I can pretty much already hear the thing tapping along the surface though so I expect the same result...

Truck seems to move along smoothly until it contacts the item, I even removed the flexshaft from the truck as recommended.

I do select Best quality and set the depth just off the board, using a credit card to touch down on.

Thanks,

Did you make sure the probe was tight in the chuck, and are you using the QC, Rock or Carvetight.

Yes the probe hasnt shifted in the chuck, I took measurements before and after the scan because I was worried about that. This one is in a Rock Chuck with the adapter sleeve. I made sure to measure because I didnt want to torque too hard on the plastic, so I was a bit worried about it shifting.

It's weird, it just seems to kind of chatter along the top instead of the sweeping dragging motion I expected. When it isnt in contact with the piece, on the air scan parts it moves perfectly smooth. I guess I will see what the scan gives me, and also try the mirror test.

Thanks,

I am under the impression that the probe is suppose to sound like a minature jack hammer.

Well then that's what I have. I just don't understand how people get such smooth looking scans if this thing is tapping along the top. Yes, for a flat surface like a knife blank it is pretty easy to clean up, but what about a detailed scan, which is what I am hoping to do..

Maybe I misunderstood. I thought the probe would scan a pretty close likeness into a pattern without much cleanup. Do you guys have to go through the whole photo editing thing to make your scans usable?

Thanks,

I have only done one test scan so far, but that is what mine sounded like.

BJB's suggestions sounds very logical to me.
