Let's see what the EtherCAT master writes in the syslog when you try to start linuxcnc.
Can you please post the say last 30 lines from syslog? Command "sudo dmesg | tail -30"
Only the ones from EtherCAT are of interest.

 

With Jumpers W5,W6 UP,UP I see the user led's light up in sequence when I power it up

CR27 lights up green
CR15 led INT keeps flashing red

it seems like I am not able to connect to Ethernet

mesaflash --device 7i95t --addr 192.168.1.121 --write 7i95t_16m_fallback.bin --fallback
No 7I95T board found

You did not program the flash, just the FPGA.
Now you should have Ethernet access so you can run:

mesaflash --device 7i95t --addr 192.168.1.121 --write  7i95t_16m_fallback.bin --fallback
mesaflash --device 7i95t --addr 192.168.1.121 --write  7i95t_d.bin

Edit: Modbus (TCP) may not be the most "modern" approach that is available but I would say that it is the most universal, well understood, and common Industrial protocol. When it comes to system support it would be hard to argue against Modbus just because so many industrial control techs know it and use it. Simple system architecture typically translates to reliability. In an industrial application, reliability is king.

good point

I have been suspicious my bad experiences with modbus was mostly related to some inexpensive hardware I used.

Probe Basic has had a NEW Stable Release made as of today February 5th, 2026

In order to update to the latest stable release it will require updating your sources.list.d/kcjengr.list file to point to the updated repository. the same goes for updating to the latest develop version, please see the link below in order to see all of the update notes!

I installed Linux cnc / Efinity in a Virtual machine, I was able to use your command.
I just needed to activate python Virtual environment.

Could you please provide one .bit file? I am afraid that I might flash the wrong .bit file again.

It seems like I manage to flash the board?
What do I do next?

@IndeeSales,
Is something wrong with your account as i see it has been disabled twice till now?

Yes, I think that command needs the IDE or al least the xml project file with paths setup properly

Do you have a 7I95T  .bit file? (if not I can post one)

 

Hey Guys, I’m pretty new here.
 I have a little Problem with configuring my Stepper online A6 Servo Drive. I want to use torque homing but I can not Figure Out wich Parameters I need to set in the Drive. 

And I also Think that my Linux CNC Config is wrong. Can maybe someone with more experience then me help me

Liebe Grüße

Thanks Rod, I managed to build a deb in a bookworm chroot but it won't install on trixie because linuxcnc requires python3.11 and trixie uses python3.13. I also tried installing the deb from buildbot2 but same result. Looks like I have no option but to reinstall bookworm. Major PITA.
On that note, I recall you posted the 6.3.0-rt11-linuxcnc kernel somewhere, but I can no longer find it. Could you tell me where that is? Thanks again.
Jim
 

OK those settings should result is a +1.0V output
(as they do here)

Possible reasons for a very different output voltage:

1. Measuring wrong pins ( analog output 0 would be measured from TB3 pin 4 to TB3 pin 3)

2. Marginal 5V supply to 7I97T

3. Problem with the voltmeter

4. Damaged 7I97T analog output driver

5. 7I97T analog output connected to shorted  load

Okay first of all thank you for all your help with this, I am very new to this and have watched countless hours of youtube on ethercat and a having a hard time finding solutions to errors. I have another error 
Failed to register PDO entry: No such file or directory
LCEC: master 0 PDO entry registration failed

I want to thank everyone again for the help, I had lost hope on my project until now.

I consider having to restart LinuxCNC unacceptable. If I don't find a better solution, I will not use this pendant.

The rotary knob sounds more like a configuration issue(?). Have you checked if you see the position switch changes by running "xhc-whb04b-6 -a" from a terminal?

Hello I try to setup a mill with all servo drives run with analog command and it's working fine.

However, now I try to setup a MPG
after customizing the HAL file, here is the situation:
the MUX is correctly working for the scale and the axis.x.jog-scale is correct (value from 0.01 to 1mm)
axis.x.jog-enable works fine, same for Y and Z
axis.x.jog-counts works fine, I can see the number of pulses moving when I turn the handle
axis.x.jog-accel-fraction is set to 1

When using Axis interface with the and - button, it works fine
However; when I turn the handle, the axis is not moving at all, I don't have any error message.E-stop is off and Toggle Machine power if ON obviously. 

Any idea what could be the issue?
thank you
 
D'après votre description, la plupart des connexions MPG semblent correctes. Le problème vient probablement de la manière dont les incréments de déplacement sont utilisés. Un piège courant est que les incréments seuls ne permettent pas de déplacer un axe si le mode de déplacement n'est pas correctement configuré. Assurez-vous que l'axe est en mode « téléopération » ou en mode de déplacement par articulation, selon que vous utilisez une configuration par articulations ou par axes. Vérifiez également que les incréments MPG sont bien connectés aux broches d'articulation ou d'axe appropriées, et non mélangés. Il faut aussi vérifier la vitesse de déplacement : même avec l'accélération activée, une vitesse de déplacement nulle ou très faible, ou une limite de vitesse de déplacement trop basse, n'entraînera aucun mouvement. Découvrez un casino en ligne retrait instantané où les jeux classiques et modernes se rencontrent. Enfin, assurez-vous qu'aucun autre signal (comme un autre canal MPG ou une source de déplacement d'interface utilisateur) ne maintient l'activation du déplacement à l'état bas pendant l'exécution.

Greetings Mark!
First of all, excellent work on the retrofit - this thread will end up being a literal goldmine for me. 
Last week I also purchased a 1986 MH400E and the goal is to convert the machine to LinuxCNC in the coming few months. 

Somewhere in this thread I saw that you have a 'collection of notes' for your conversion - is there any way to get these from you? I can't seem to find an email-adress available on your YT Channel as previously stated. 

I haven't quite had the time to work through all 180 pages, but I do have a quick question: 
How is the gear-changing generally handled? Do you have to command an exact speed value, or will LinuxCNC pick the correct gear for whatever arbitrary speed you command? 
Also, will the gear-change happen automatically whenever a speed is commanded, or is there specific codes that need to be ran (I would love to use the F360 CAM and I wonder if linuxcnc will handle selecting the speed automatically, or if I need to fiddle around with the post-processor?) 

Thanks and very best regards from Germany
Daniel
