Hi Bernd,
You are making progress.
Set PWM Base Frequency to 100 (spindle setup)
Set Output #1 to Active Low (output signals)
Set Clockwise (M3) to Output #1 (spindle setup)
You need to add spindle speed to your Gcode (S0 = minimum PWM ; S100 = maximum PWM).
You need to be using Mach3 version R3.043.056 or later.

If you wish to test the circuit / setup
without it being connected to the laser PSU
then temporarily connect the components shown in red.
With this and when Mach3 is set-up as described then the commands…
M3
M11P1
S100 should indicate 5 Volts
S50 2.5 Volts
S0 0 Volts
Etc.

Hey Tweakie
I assembled everthing like you told me. I have version R3.043.066 and adjusted all the things as you texted me.
To get everthing right, should i connect a 5 volt source (4,5 also possible?) as +pole with the 10k , the -pole with Gnd and place the gauge in between?

4.5 Volt would be OK, connect as shown in the diagram (+pole to the 10k and -pole to GND).

Hey Tweakie
Last time to be totally sure...is it at the 1st picture a 10k resistance and at the 2nd one a 10k potentiometer?
1.)
2.)

Hey Tweakie
I have set up the curcuit layout without the power adapter and 4,5V battery and it works. But it shows me at OV at S100, 2,25V at S50 and 4,5V at SO, shouldn't it be the other way?

That sounds correct.
When using the TTL(L) input to the laser PSU 0Volts is maximum laser power output and 5Volts is minimum laser power output.
However, to reverse the voltage slope just change the Step Low Active state of the Spindle (Config. / Ports & Pins / Motor Outputs).

Hey
Thanks for your help, now really the very last question, is it mandatory that the potentiometer has 10k? cause i don't have a 10k one

It is not mandatory. I would think any value between 1K and 22K would be OK.
(I use a 10K, 10 turn, potentiometer with calibrated dial).
