TTL (PWM) Laser head and Mesa 7i76

Also the readhmid output shows the original firmware (5i25_7i76x2)

Now I think everything is correct, the configuration I had is operational again and the --readhmid returns this file to me.
How do I identify the output pins of the StepGen and PWM on the Chinese card? I mean, the Step5+, Step5-, Dir5+, Dir5- for example

Hi

I am running a Mesa 7i96 where I have used all 5 stepper outputs and also would like to add a PWM laser control.

Would any of these cards do it?

Thank you so much for an answer.

If used to buffer a PWM output from P1, probably any would do

Thanks for the quick response.

Would I need to re flash the FW on the breakout board as you talked about before?
in that case how do I go about that.
Or what do I need to add in my hal file?

Sorry have not worked with the hal file in some years.

This is the kind of cable right?

7I96 (NOT 7I96S) configuration with 1 PWM
output on DB25 pin 2

 

To update your firmware, you would

mesaflash --device 7i96 --addr [card_ip_address] --write 7i96_p1pd.bit --reload

Those cables look correct

I believe there is a thread on laser PWM that may help with the hal setup
