Auto air assist relay

Hi, I have the Sculpfun S10 laser, and I wanted to set up automatic air assist from this side: Relay Control - Diode Laser Wiki, but I’m having an issue because the pin is always in a high state, and the M9 command doesn’t reset it. Has anyone encountered this problem before?

Make sure it is Pin A3, not Pin 3. Also, I seem to remember it as Pin A5 when I looked into Air Assist for some reason, although the Wiki says A3, so you might try to see if that pin cycles with M8/M9.

But this is Sculpfun S10, not S9, and the motherboard is slightly different. The pin I connected the coil to is IO04 in the S column, but it remains in a high state all the time.

S10 Guru, we need a cleanup on aisle 4.

I dont understand :thinking:

Translation: We need an S10 user to jump in and help with the problem.

My lame attempt at American humor. My bad!

Ohhh ok :joy:. Let’s hope that someone has encountered a similar issue and will help.

I can try. Did you notice that there is a S10 section as well? It has a different mainboard. Or dou you even have an S30 mainboard? Maybe share a picture.
