Changing the OS/LinuxCNC version is a complete waste of time.

This is most likely a hardware or hal file setup issue.

I explained how to debug this issue, but was ignored, I'm out.

 

I performed a fresh installation of the entire system.
I updated everything.
configure the wired network connection to the motherboard and check with the PING command
using the wizard I created the configuration 7i76e (it did not allow me to configure TB4)

- Linux 6.1.0-39 rt
- Linuxcnc 2.9.5 
- New config Pncconfig wizard

 

This is not a LinuxCNC version issue.

This is a hal setup or hardware issue.

1. Do you have +10V on 7I76E SPINDLE+ relative to 7I76E SPINDLE- ?
2. Can you set the spindle speed to 1/2 way up and then run:

halcmd show all  > all.txt
 and post the all.txt file here

(you run halcmd from a terminal window when LinuxCNC is running)
 

It won't have anything to with the Linuxcnc installation. If there was an issue, something missing, Linuxcnc would produce an error.

Maybe if you could take a picture of the power wiring to the board, that may show something. I've looked at things in the past for hours on end and missed a simple error.
I can understand how things can get very frustrating.
I take it you have measured the output voltage when not connected to the spindle input ?
The spindle does take a variable voltage and not a pwm signal, just asking as you were concerned about not being able to select pwm. Sorry for these simple questions, please dont take them as an insult .

thankkkkkkkssssss !!!!!!
I have performed all the tests before starting the forum. It does not output 10 VCC, it does not regulate voltage, that's why I started the thread.
I am confused with this situation, the board was working perfectly on a lathe with version 2.7.15. Now I need to install it on another machine. I tried 2.8 - 2.9.4 - 2.9.5 the result is always the same, it does not regulate voltage. But there is something that is not connecting, linuxcnc shows good operation in Halshow, but it does not go out through the 7i76e.

I am going to reinstall linuxcnc from scratch again and see what happens.
thank you all for trying to help me!!! I'll post updates soon!!!
 

I think it may have been a typo, but even then, there is a far better way to have multi versions of Linuxcnc, that's the beauty of building from source, if you can follow instructions you can do it, and taking advantage of the run in place facility, aka RIP.

Your HDD probably has enough space to dual boot LinuxCNC 2.9.4 and 2.9.4.

Why? What's the point of having two of the same version?

Could it be that I am not using the correct version of LinuxCNC?

No, any version of LinuxCNC from 2.8 on will work with the 7I76E

Like I said you need to check


hm2_7i76e.0.7i76.0.0.spinout-minlim  
hm2_7i76e.0.7i76.0.0.spinout-maxlim   
hm2_7i76e.0.7i76.0.0.spinout-scalemax 
hm2_7i76e.0.7i76.0.0.spinena-invert  

 hm2_7i76e.0.7i76.0.0.spinout
hm2_7i76e.0.7i76.0.0.spinena

with halshow

In axis, you can run halshow with:

Machine --> Show Hal Configuration --> Watch

And also verify that you have +10V on the 7I76E SPINDLE+ pin
(TB4 pin 3) relative to SPINDLE- (TB4 pin 1)

 

You may try 2.9.4 if you like.

www.linuxcnc.org/iso/linuxcnc_2.9.4-amd64.hybrid.iso

Your HDD probably has enough space to dual boot LinuxCNC 2.9.4 and 2.9.5.

When you tried to update the repository (sudo apt update), how was the PC connected to the internet?

You should be able to debug spindle operation by using halshow
to look at the spindle pins as you set the spindle speed to different values
Important things to watch are:

hm2_7i76e.0.7i76.0.0.spinout-minlim  
hm2_7i76e.0.7i76.0.0.spinout-maxlim   
hm2_7i76e.0.7i76.0.0.spinout-scalemax 
hm2_7i76e.0.7i76.0.0.spinena-invert  

 hm2_7i76e.0.7i76.0.0.spinout
hm2_7i76e.0.7i76.0.0.spinena


Also make sure then the electrical connections are correct
(so you have 10V from SPIN+ to SPIN-)

I was able to correct the IP address
it doesn't work, I can set cw-cww-enable but no speed.
I am trying to update and it cannot find the linuxcnc repository , gives an error
I am using 2.9.5

Should I reinstall everything again?
I don't understand what is happening

Yes, the sample file is set for a 10.10.10.10 IP address
if you are using 192.168.1.121, you will get that error
 

Is the networking set up for Mesa?
Is the IP address on the board set same as in the config?

Houston !!! i have a problem!!!
