The first step is to open the stl file in the make orientation of the model as per the orientaion of the wax in the SRM-20.

The next step is to generate the .prn file by creating the two processes i.e finishing and roughing file from the modela player.
### Creating the Roughing file.

the 10 mm indicates the width for the silicon walls of the mold. This will help in creating a mold that would hold the casting material.

For the roughing process we will be using the 3.145 square end mill to create the roughing profile.

We had the cutting area and depth area. And set the start height to 5mm, so that there we a some thinkness in the negative mold to hold the cast later.

The tool path for the roughing process will be contour lines (Upcut).

Finally roughing is done after 2 and half hours.

### Creating the finishing file.
Now the next step is the creat g-code for the finishing file. Not much of a difference, we have to change the tool to R1.5825 Ball.

And the next step is to set the tool path to scan lines.

Now make sure that we have saved the g-code file to a proper location.
