Invert logic output H3

[flopo76]

Hi,is there a way to invert signal output on H3 (heather3). Now i have M3 S255 and my laser is off and on with M3 S0. I need to invert,but how?

Thanks

If you are using M452 to put the machine to laser mode, and you are using the P parameter in that command to set the pin for the M3 command, then you can also use the I1 parameter to invert the output. Looks like I forgot to document it in the GCodes wiki page.
