Bonjour, je possède un laser de 5W qui fonctionne parfaitement, mais j’ai voulu changer pour un laser de 20W et le problème c’est qu’il reste allumer il y a un switch d’allumage au dessus, apparement je n’ai pas de oscillation TTL il me marque les ligne de déplacement à fond tout le temps !! voir la photo jointe, merci

Hello, I have a 5W laser which works perfectly, but I wanted to change to a 20W laser and the problem is that it stays on there is an ignition switch above, apparently I don’t have no TTL oscillation it marks me the lines of displacement at the bottom all the time !! see the attached photo, thank you

Check the pins on your old module vs your new module. Make sure that the pins match. If they don’t you will need to modify your connector or get a different cable.

Thank you but it’s exactly the same connections, picture of my LASER PWM controller

It’s very hard to read but the connector for your old module looks like:
GND PWM 12V

The new module in the same orientation is labeled:
PMW GND 12V

Can you take a closer look at the markings and make sure? If so, that’s the source of the issue. You will need to swap the PWM and GND pin positions.

Thank you very much, great the problem is solved and also it was necessary to make $32=1
