[SOLVED]How to configure the PWM signal in a MESA 7i96 for a spindle?

At the minimum. you would need to link the software PWM output pin in
hal to the SSR used for PWM output.

Ok, but what is the pin? I have tested all of them and it doesn't work.
I'm sure it's easy but I don't see it

pwmgen.0.pwm

so for example

net myslowpwm pwmgen.0.pwm hm2_7i96.0.ssr.00.out-03

hi, i have tested it but no work

It does work but you need to setup the PWMGen parameters and connect the
required PWM pins

Did you read the pwmgen manual page?

Can you post you current hal file here?

Hi, well it's already solved, I followed this manual
linuxcnc.org/docs/2.8/html/examples/spindle_en.html

The problem I had was in the parameters. Now I have another problem, I have broken the optocoupler of the spindle electronics, I did not realize it and it connects 5v directly from the source and I did not put a limiting resistor on it and I have broken the diode, tomorrow I will buy a replacement to repair it ;(

Hi, good day everyone, sorry by delay i'm had very work.
I repair my electronic of spindle, i have change the optocoupler and at now my spindle work fine, better than i used the previous port (TB1/TB2 port 4)
but at now i want to use the other port TB3 (output 1) for other PWM signal, i want to install a laser of 20W.
I have add other spindle at the HAL in the linerMAX_SPINDLES = 2 in the archive .INI

It's generated other PINS whit the spiendle 1
I configure all like spindle 0 but changeing few names custom.


Whe i try run the spindle 1 with command M3 S1000 $1 the menssage the LinuxCNC is invalid spindle number in spindle speed command
Can someone help me

Hi i'm stuck, can someone help me to set two spindles?
thank you

Ok, thanks you so much
