I have designed my first Laser engraver
I have the Mini Gerbil controller
I`m going to test NEJE 2.5W and 5.5W Laser diode (PWM/TTL)
After some “googleing” I found that I should use " RF excited tube" mode to get the best PWM results, but I cant find how/where to alter laser mode/type.
I have connected the laser to 12V and the PWM output on MiniGerbi - but when I test the “Fire” function the laser stays on when I set fire = off
The laser have 4 pins
