I'm still searching for a g-code to access PB7 connection point.
Sailfish doesn't actually know any g-code. All g-code gets translated into x3g protocol before being sent to the printer. You can look for what you need in the x3g protocol: https://github.com/makerbot/s3g/blob...s3gProtocol.md

I'm afraid you won't though because I can't think of any PWM you can command directly through x3g. There is PWM in the firmware, but they're indirect. That is they're commanded by the firmware to achieve a goal (like heat the bed or make the LEDs a color).

You could write in your own bit into sailfish (that's what ZYYX did for their autolevel feature), but if it needs a new x3g command that could be problematic for compatibility.
