Dental Wings Scanner 7 Series Scan issue

[kotharyabbas]

I have a S107 Series Dental wings scanner and when I scan the model the scanner makes a lot of noise as if its grinding something inside while it moves. My images are totally seen as broken patches after the final scan. Has any one ever experienced similar issue. Please guide what is the solution to this problem. I am to far from Dental Wings Montreal where I can send the scanner for repair. HELP, HELP, HELP>

It would be nice to upload some pictures (screenshot) with your scans.
One problem could be the color of your gypsum model, try another color (you can try with ordinary gypsum, just for experimenting). Is it new? its the first use? was it ok in the past ?

First of all contact the guy who sold the scanner to you . And then the one who supports you .

 

[Jo Chen]

Have you been using the scanner for a while and this is a new issue or is this the first time you are using the scanner?

 

[martintay]

Sounds mechanical ? I think Drizzt is completely right if you have that option ?

It must be mechanical issue. Most likely your model is to big. I don't know about 7, we have 3s, I would open the door during scanning and see what was goin' on. I had similar issue while scanning some big partial models.
Solution was to drill two dead holes in the model from the bottom, distanced same as stop screws on holder.
Tightened the screws so model seated flat on the holder with the screws in the holes. That was it, problem solved

P.S.
The screws are M8 size, the drillbit needs to bi bigger, 9 or 10 mm in diameter.

Obviously, you need to contact you dealer...

only expert of this scanner can told you whats going on...

I am no expert for DentalWings specific scanner, but this sounds like an easy thing to diagnose and fix.

Just like any CNC mill or scanner with motors and control system.

Piece of cake...?

Rotary Axii are direct drive, or with belt and pulleys?

Maybe loose belt, or gears meshing incorrectly?

Physical obstruction?

Take cover off scanner and check it out of course!

Post some pics!

I wanna see inside your scanner.

Stepper motors, or Servo? Maxon motors perhaps?

If it sounds like it's growling at you during a scan your rotator arm is probably going out. How heavily is the scanner used? We were able to use ours until the part came and replace it ourselves. 800$ fix for the 3 series, contact dental wings and they will hook you up, very good technical support in my experience.

I agree, great technical support from Dental Wings. I've never looked inside a 7 Series, but I have seen the inside of the 3 and 5 Series. No belts, just stepping motors.

Hello All,
I want to thank all you good people for posting all your comments. I am currently in talks with Dental Wings regarding this issue.

7 Series scanner has no belts.

We bought this new scanner in 2012 so its been almost 2 years now. Do you think it should be worn out so soon. By the way we only have one scanner so all the scanning is done on this one scanner.

I would like to share with all of you members the actual scan output result image so all you members can review it and advice me if you have seen anything similar happening with your scans and what did you do to fix the problem. Thanks
