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

do you still have this line in the hal file:
setp hm2_7i96.0.pwmgen.00.out0.invert_output true

and are you using the STEP4- output?

When you invert the PWM output (the statement above does this)
The PWM output on STEP4- should stay low at 0 PWM

no, I didn't have that line in the HAL file. I have now write it and it works perfectly.
How can I raise the frequency so that the spindle goes faster?

You should set the PWM scale to the maximum RPM value
Then the PWM will be at 100% duty cycle at the maximum RPM setting

Note that the PWM frequency needed is determined by you interface
hardware and may need some testing if not documented

ok perfect,
For this configuration I have used the custom.hal file and it works fine.
can I use multiple ports for PWM signals and have two PWM signals?
can I use a TB3 output for a PWM signal?
Where can I learn this language to be able to make my own configurations?  

Yes, you could have two PWM outputs on TB2 instead of PWM/DIR
with different firmware

You can use TB3 outputs for PWM, but only at quite low frequencies
because they can only be changed at the servo thread rate. For
example to get 1% resolution PWM at a servo thread period of 1 ms
you would need to have a PWM frequency of 10 Hz

To use TB3 outputs as PWM you would use LinuxCNC's software
PWM componant

I do not understand this:
To use TB3 outputs as PWM you would use LinuxCNC's software PWM componant

Could you explain it to me a little more?

So, would it be possible to add a laser module to my CNC and use another output to activate the laser and generate another PWM signal, that is, my CNC would be a router and a laser with the same firmware?

Hi. I'm sorry but I don't understand that language, I know how to program in C but not this and I don't understand it, I don't know the rules to understand it, and the documents that exist don't help me, they explain for people who already have knowledge in this language.
I need help to understand
If it's not too much trouble, can you give me a step-by-step example of what to do to configure a PWM signal on TB3 output 0 to drive a spindle?

hi, i think i understand some of linuxcnc but i'm stuck.
I have added the pwmgen component to the project only one generator
I have added the functions
and I have configured the parameters
but when showing the HAL configuration I don't see any changes on the pins.


I see that the TB3 outputs are solid state relays, when the hm2_7i96.0.ssr.00.out-00 for example
output is activated when i tipe in the MDI tab M03 S300 a contact is closed. I think that pwmgen acts on the relay closing and opening and creating the PWM signal

what am I missing?
