Please note that the product cannot enable or disable the blowing function based on layer selection, but the blowing function can be temporarily turned off in the software.

To disable the air assist function while engraving, you can follow these steps:

1. Open RDWorks and select vendor settings. The password is "RD8888"

2. Uncheck the enable blower.

There are the same options in Lightburn.

Note: Turning off this option will also interrupt the power output to the exhaust fan on the machine. It is recommended that you plug the exhaust fan directly into a household outlet to ensure proper smoke ventilation.
