DiaMark
Q: I have defined saw and/or cut planes on a rough stone, but when I mark them, the line is apparent only at parts. Why does this happen?
A: The marking of the line on the rough stone is achieved by combining two motions:
 The rotation of the stage - 360°.
The movement of the laser source - Z axis (up and down).
The laser is calibrated in a way such that its focus lies very near to the center of the stage, ±200 microns (±0.2 mm) horizontal tolerance (though the actual shift off the center is much less usually).
Any point on the stone's surface that can be brought (by rotation) to the laser beam can be marked on. Because the laser cannot be moved horizontally, all the points on the stone that stay above the very center of the stage in all rotation angles will never reach the laser, and hence will not be marked. Obviously the face of the stone which lies on the stage cannot be marked either.
In order to achieve the best marking results, it is best to place the stone on the stage in a way such that the planned saw/cut plane is as parallel to the stage as possible. In that way, all the points on the line will reach the laser at some time during the rotation of the stage, and a full line will be marked.

Laser Mapping
Q: Why is it necessary to cover rough stones with the white solution before performing a laser mapping?
A: The white solution creates a matt coating on the surface of the rough stone. This prevents the laser beams from breaking and reflecting when they reach the stone's surface. Without the coating, the laser mapping can be distorted because of the stone's natural transparency, and the resulting model of the stone would be inaccurate.
Q: I am considering adding the laser mapping capability to my DiaMension machine. Is it better than regular (optical) mapping?
A: Laser mapping is needed for working with concave rough stones (i.e. stones which have holes and crevasses in them). If you only work with stones that have smooth surfaces, you do not require laser mapping capability. Optical mapping is just as good as laser mapping when the mapped stone is not concave.

Reports/Labels
Q: Is it possible to create my own label, which includes only the data that is relevant for me?
A: Yes it is. Different users require different information when generating labels and reports from the Sarin system. Contact Sarin support if you want to customize your labels and/or reports for DiaMension, Brilliant Eye, or DiaExpert. If you are using DiaVision, simply select Tools | Views/Reports Editor to edit and create your custom reports.
Q: I am using the DiaMension and DiaExpert applications. When I print labels, sometimes the first row is missing or trimmed. How can I solve this?
A: In DiaMension: In the Definitions section, Directories_Printers tab, click the Label Printer button. In the Frame titled Margins, you can adjust the position of the text on the label. Top sets the distance of the text from the top of the label; Left sets the distance of the text from the left end of the label. Values of Top and Left are usually between 0.0 and 0.3. Click the OK button when you are done.
In DiaExpert: In the Reports section, click the Label button, click Settings. In the Frame titled Margins, you can adjust the position of the text on the label. Top sets the distance of the text from the top of the label; Left sets the distance of the text from the left end of the label. Values of Top and Left are usually between 0.0 and 0.3. Click the OK button when you are done.

Upgrades
Q: I have a Sarin machine, and I want to upgrade my computer to one with a Pentium IV processor and windows XP, so that I get better performance. Are there any implications?
A: Generally speaking, a typical Sarin system consists of many parts:
The machine on which stones are placed and measured.
The software through which the user sends commands to the machine and receives results.
A control card through which data is passed between the computer and the machine, and
a frame grabber which handles the capturing of the different images taken from the stone.
The computer on which the system is installed.
The operating system which is installed on the computer.
Not all software versions can work with all cards, not all cards match all computers, not all operating systems support all cards, etc.
Since there are many possible combinations of these elements, some of which are supported and some of which are not, you should never attempt to upgrade your system without consulting Sarin Technologies support first.
