I need help. How do I get signal from lightburn software. To control air assist. Which pins can I use with this version of the board. ?? Thank you very much.

If this is running MKS firmware you can try to locate the IO04 pin. Can not see it on the labeling. I also can not see an i2C header (SCL pin). If it is not exposed on a header you can solder a wire directly to the related ESP pin.

SCL pin is high by default on my board. Obviously when I connect it to my relay module it sets the relay ON which is not what anyone would expect. Can the default state of the SCL pin be set to low so that we can turn it on and off with the G-Code command when required/cutting? My relay module

Also, Is it possible to use the I2C header and protocol to address a I2C relay? board

There are relay modules available wich have an opening and a closing contact. This can solve your problem.

For this one you need to connect power to 5V. 5V is available at the probe connector.

Yo may also take a lock here how i solve the problem:

The relays in the drawing looks to have both NC Normally closed and NOpen. So should be no prob, as long as you get a signal to them, either way.

I will give that a try... I did not consider reversing the relay, was focused on the board.
