Post Processing (CAM)

Once you have created a CAM profile, the CAM needs to be converted into gcode, the programming language that is used by the CNCs in order to run the machine. This "translation" is called Post Processing, and there are a few minor difference when working with the OMIO CNC (small one) versus the Laguna CNC (big one). Follow the steps below to correctly post-process your CAM.

1. Try to organize the operations so that multiple operations requiring the same tool are consecutive. Any operation that creates holes should be first in order to allow the user to add screws to the part and prevent it from moving under further operation

2. Select all the operations that use the same tool and also meet the screw-down-the-part requirement

3. Click Post Process, and make sure the configuration is set to Laguna CNC or CNC Router Parts (OMIO). (These post-processors can be found in the MVRT Parts Library, inside the CNC folder)

4. Change the file path as needed

5. Rename the file to reflect the operation and the tool used, commonly used format: <letter of order><tool diameter><descriptor> For example: A196drill, B25adaptive, C6mmcontour, etc.

6. MAKE SURE units are in millimeters since our CNCs uses millimeters

7. Save the file with a PRG (Laguna) or TAP (OMIO) extension

OMIO-specific Details:

- The Omio will use the speeds and feeds from the first tab in the CAM, so while it wasn’t necessary to adjust those values when working with the Laguna, it is necessary to adjust those speeds when working with the Omio. For now, use the same speeds as the Laguna (such as polycarb endmill (laguna) - 300Hz; in cam for omio - 18000 rpm (1 Hz = 60rpm)). After further use a table with the values for the Omio will be available.
