Machine: replace this text with what machine you have and what controller it came with

Board: replace this text with what board you have (LaserBoard, Mini, or Remix)

Firmware: Smoothie or GRBL-LPC? “I have a new board and I’m using whatever it came with” is also a great answer!

Problem/ Question: Please provide a detailed description and pictures of your machine/ board/ wiring.

Did you provide those pictures? We need pictures to understand your setup!

That’s the optiosolator. The part you need is a LTV-217-G by LITE-ON.

On your second photograph, pin 1 is the top-right.
