Description
The FoxAlien PWM Smart Relay Module is designed for controlling the CNC add-on such as FoxAlien VFD Spindle and vacuum cleaner when using the CNC machine. It can also work with the laser engraving module and air assist pump. It can allow the controller to turn on/off those add-ons automatically.
Works exactly as expected. Would have been better if there was a 10 second delay before vacuum outlet turns off to clear dust (chips) from hose.
I find having this item to be very handy. I mainly use it when I have my 40W Laser on my CnC. I love the fact that it turns on the Air Assist automatically
