If I put the enable option back to 0 it works, not perfect but better than before see attached

If I put the enable option back to 0 it works, not perfect but better than before see attached

Correction - sorry that's because it was in pin 2, I just tried it as advised by Opt Laser

step by step:

-put it back to mode 2, witch should enable laser beam by using input1
-MDI M3 S1000 -> beam should stay off
-measure with between GND and input1 (input1 disconnected)
-if you measure the 4.9v make link from Input 1 to  GND

I get 28mv thats it

this Manual (https://optlasersgrav.com/index.php?controller=attachment&id_attachment=56)
say's Mode 2 will enable Laser with Input 1 High
and on page 20/21 Hight Level is from 3-24V so for the Moment i have no answer why it's not
starting if you put 5V to terminal 3 (after M2 S1000)

maybe Manual is wrong.

pls check the voltage between Pin3 and 4 when the 5V are connected.

4.95v Between pin 3 & 4

4.95v Between pin 3 & 4

but laser is not turning ON?
Mode2?

No

so maybe contacting

contact@optlasers.com

would be an Option, for the Moment i can't see, what we are doing wrong.
