Hi Jeff,
thanks for your quick answer.
So am I getting it right that the TTL on the 3-Pin Connector should be12V, right? So I should not connect it to Pin44, then because that would be a 5V-Pin?
The way I understood it is that you need the fan port (D9?) to switch the laser on and off and the 5V-PWM port to change the power of the laser. At least that is what this German website says:

Here is the way they’d wire it up:
Or am I missing something?
So I should wire the 12V to D9 in order to switch it on and off using M106/M107.
Then I wire the TTL/A+ on the white wire to Pin44 and that way I am able to control the power as well.
Is that correct?
But why the heck are there 3 pins for TTL?
