Hello,
I try to configure according according

but when I add
addf pwmgen.make-pulses base-thread
I receiving an error
Do you have a base-thread?
That example probably comes from linuxcnc and relates to a rtai kernel
What happens when you attach to the servo-thread?
Also I try that

What I did wrong?

The scale HAL component should do exactly what you want:

You can set a gain and an offset value to convert the 0 -1 input
to a 40-60% of an PWM output value.

Hello,
I have BlackBuck 8M laser diode driver
(http://www.ebay.com/itm/BlackBuck-8M-8A-Buck-Laser-Driver-NDB7A75-NUBM44-NUMB05-NUBM06-NUBM08-/122257691806/?_ul=RU

with next spec
modulation input 0-5V or 0-5V TTL/PWM
Frequency - 4kHz
Modulation rise/fall time - 40/60ms
I user arduino as TTL generator everything are ok but when
duty cycle around 40% - 0% laser power, duty cycle 60% - 100%
laser power
Question possible to config on BBB
0-40% duty cycle - 0% laser power
60-100% duty cycle - 100% laser power
and for example
41% duty cycle - 5% laser power
40,2% duty cycle - 1% laser power
40,5% duty cycle - 2,5% laser power
etc
another solution?
