Hi Shaun,

I googled 5040 laser and found this link, please confirm this is what you've got https://www.aliexpress.com/item/32315846861.html

Here's a photo of power supplies from the above link:

Which I guess is what your drawing relates to?

There's dozens of different laser units out there and we don't own all of them, so we haven't got a pre-canned wiring solution for the 5040. But we have helped many laser owners get their laser sorted when they can patiently provide us all the details we need.

Best way to start is a good quality (high resolution, with good lighting) photo of your power supplies, so the terminal labels can be seen.

Keep in mind that for a laser to operate it needs two signals: the PWM and the LO. Your drawing shows the PWM connected, but where have you connected the Gerbil's LO to?

Regards,

Dan
