Hello, does someone use cohesion3D laser board? I need some photos from the back of it. I managed to burn something on mine

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.

Thank you very much

That’s correct - the pin with the divot immediately beside it is pin 1.
