UV LEDs Shutter

Hello! how are you? I have a problem when using the shutter of the UV LEDs. For the configuration of electronics that I have, it would not be working properly, it works inverted. When the LEDs should be turned on they are off and when they should be turned off they are on. Is there an option to invert the command to open or close the shutter without modifying the electronics? Thank you very much!

Re: UV LEDs Shutter

What "electronics" are you using to run the LED's? With the relay board i am using you can connect to the normally open or normally closed side of the relay, you could just move 1 wire to change this. Also post the gcode you are using.

Re: UV LEDs Shutter

I'm using this configuration:

With a Mosfet Irzf44n. I have to use the other transistor because the mosfet don't gate on 3.3v from the raspberry.
And I don't know to much from gcode so I don't touch it.
Thank you!
