In this section we will get your drawing file loaded into SheetCam. We will change a few settings and get SheetCam ready to create some tool paths for the KRMx02 CNC.
We are going to start with a simple gear I have setup in CorelDraw.
It's a small gear inside a 2" x 2" square. Note that I almost always add a rectangle around my part that will represent the stock I will be cutting to make my part.
In this case its a piece of 2" x 2" soft PVC plastic
By doing this you assure the location of your part in the stock you are using. Granted there are many other ways of referencing the part, but I have found this to be the easiest one to start with.
I select my gear, the box, and the shaft hole and then select "Export" from the File menu.
You want to export the part as a dxf for SheetCam. Select DXF from the "Save as type" selector.
Give it the file name "small gear.dxf" if it has not already done so.
Hit the Export button when you are ready to save the file.
Load SheetCam, then make sure you have Rotary Cutting selected in the Machine type tab shown here.
You can bring up this dialog by selecting "Machine" from the Options menu.
Move to the Post processor tab and set it as shown here:
(Click to Enlarge)
Change to the Working envelope tab set the size build of your KRMx02.
In this case I'm using a 30" x 27" KRMx02.
Not that if you have set your KRMx02 as metric these numbers will be the metric equivalents.
Click the OK button once you have verified all the settings.
From the File menu select "Import drawing".
When the dialog pops up, navigate to the location where you saved the small gear DXF file and load it.
You will be presented with a dialog asking how you want to reference the drawing.
Select the Inch (or Metric) option and make sure the lower left corner of the Drawing position has been selected.
SheetCam should look something like this. Most likely however, the part stock is not set correctly.
Form the Options menu select "Job Options".
Select the Use drawing checkbox then set the options as shown and click ok.
Now, your SheetCam window should look like the one shown here. You can use the mouse wheel to zoom in and out.
If you select the "View toolpaths" option shown here, you can drag the part around in order to position it better.
At this point SheetCam is almost ready to create some toolpaths. First we need to add some tools.
