I hope I'm right

Hi everyone.
I’m writing this to make sure I don’t let out any of the blue smoke when I turn on my L4 (it works best if it stays where it’s supposed to be)

I’ve spent a long time searching for guides before posting this. But I just seem to have gotten more confused, and by no means friends with wires.

Have I misunderstood something?

Laser:
pwm_hz: 5000
output_pin: gpio.27
enable_pin: NO_PIN
disable_with_s0: false
s0_with_disable: true
tool_num: 0
speed_map: 0=0.000% 1000=100.000%
off_on_alarm: true

You have GPIO 27 in the config but your diagram has the wires going to GPIO 26.

GND for both your jackpot and the laser ought to be at the same potential.

See, that’s why you should always ask an adult first… But I’m not entirely sure I understand all that Gnd stuff. Do you mean like this?

Laser:
pwm_hz: 5000
output_pin: gpio.26
enable_pin: NO_PIN
disable_with_s0: false
s0_with_disable: true
tool_num: 0
speed_map: 0=0.000% 1000=100.000%
off_on_alarm: true

You need to put a line from the Ground for your jackpot power supply and your laser power supply together. That way they share a common ground

Like this?

On mine I took a single black wire from the ground connection on the jackpot to the ground connection for the laser. It just ties the 2 together. Sorry I don’t have a fancy drawing

Your first picture was almost right - so long as your config matched.
