Switches on or off vacuum sections that are used this is especially useful for large machines with different vacuum sections.
The software will determine in which section will be machined, then this command will switch only the used sections.

### Enabling the feature

The configuration of the vacuum sections is currently not available in the GUI settings, and it must be entered in the configuration file, which contains all settings.




The definition of the vacuum sections is manually in the cnc.ini for version 4 of the software and server.ini file inside the *config* directory for version 5 of the software, under section *\[VACUUMBED]*.

To enable this feature please modify the files (while the software is turned off) by specifying `automaticMode = 1` to turn the automatic management of vacuum sections on, and specify the number of vacuum sections:

:::BlockQuote
\[VACUUMBED]
automaticMode = 1
numberOfSections = 14

:::

Afterwards please start the software. The software will modify the file further with definitions of individual sections. Close the software and open the file again to modify the individual sections:

:::BlockQuote
\[VACUUMBED]
...
section\_1\_OutputID = 101 ;0: none, 1-10: AUX1-AUX10, GPIO101 GPIO408
section\_1\_XPosition = 0.000000
section\_1\_YPosition = 0.000000
section\_1\_XWidth = 999.000000
section\_1\_YWidth = 3000.000000
