sorry spoke too soon
there are 4 pwm in the terminal command but hal stop on the pwm freq line. i tried it with a hyphen and an underscore
here is my relevant info

try this:
setp hm2_5i25.0.pwmgen.pwm_frequency 1000
setp hm2_5i25.0.pwmgen.00.scale 100
net pwm-enable <= motion.motion-enabled => hm2_5i25.0.pwmgen.00.enable
net pwm-output hm2_5i25.0.pwmgen.00.value
This assumes pwm-output is a signal that has the current desired PWM value
And delete this line:
loadrt pwmgen output_type=0
Note: if you have a issue with names, you can list all pwm related pin/parameter names with
halcmd show all | grep pwm
(when LinuxCNC is running)
setp hm2_5i25.0.pwmgen.pwm_frequency 1000
setp hm2_5i25.0.pwmgen.00.scale 100
net pwm-enable <= motion.motion-enabled => hm2_5i25.0.pwmgen.00.enable
net pwm-output hm2_5i25.0.pwmgen.00.value

Replied by mmt on topic neeed help with additional pwm 6i25 and 7i76
now i have no idea what is going on.
with the 5i25_7i76x2_2pd loaded my hal does load the pwm without alarm (i have not checked actual output though) but my A(3) axis does not work. If i revert to 5i25_7i76x2 A axis is good but obviously no pwm
???
thanks

another question
i know the standard io pins can not pwm very fast.
i only need 10K freq can they acheive that?

There are only 3 stepgens per 7I76 in that configuration, so that's expected.
You probably need a configuration with just 1 PWMgen per 7I76.
I can make one when I get a chance.

Not likely, you need hardware PWM for that.another question

i am assuming by your lack of a firmware file one needs to be created. Is there a way I can do this ?

nevermind i got ahead of myself i now see you said you could create one. That would be much appreciated.
Thank you for all your help

5i25/6i25 firmware for 7i76X2 last stepgen (04) on each 7I76
replaced with a PWMgen
replaced with a PWMgen
