I guess I never tried access to 192.168.1.121?
I have always used 10.10.10.11

Here is that log

If I am not careful the whb04b crashes and only way to restore function is to restart linuxcnc.

I have found it happens when the display does a big re-organization.
Typically I just finished in Auto, with a certain screen layout.
Then I jog in any axis: The HMI switches from Auto to Man, can also be MDI to Man,
the screen re-organizes, buttons appear. At this point it is 50-50
if the whb04b crashes. 
I have learnt to avoid using the whb04b to switch modes, and now the whb04b works many hours/days.
It looks like something does not like the relatively long wait for the screen
to rearrange. Happened in Gmoccapy, qtdragon and qtdragon_hd.

Okay, I mostly understand. Configuration of the pendant is a bit clunky. Nice that you got it working somehow and good on you for posting the solution.

I am mainly thinking about improvements to the driver and/or firmware. Of course, configuration could maybe also be improved, but that would not be the priority for me.

yes I dont know what keeps happening I have registered 3 times in 72hrs.

Did you have card access before at 192.168.1.121?

What does

ip a

report?


Also with W5,W6 = UP,UP, the fact that the /INIT led blinks means that
the fallback configuration in the flash EEPROM is valid and still works...
 

I doubt it uses step/dir internally. With a built in driver it most likely
skips that and energizes the coils more directly.
At last that's what I would do.
And then it keeps the count just as a way to determine position,
but not connected to a performance parameter.

I already asked this question in the forum a few days ago. 
[solved] XHC-WHB04B-06 rotary knob button feed rate not work

No, the head is working perfectly and all pins are there.
There is just no signal for the feed in program mode.
You need to tap this  from whb.axis.[joint].jog-scale and convert it.

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!

kcjengr.github.io/probe_basic/update_notes.html

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?
