One thing that might be worth of note, as development moves along, is to check the Makelfile in the top of the directory as minor revisions can change for the the rpi-linux kernel.

Or you can run

Analog voltage from inductive sensor? Is that the position sensor for the ram/cylinder?
Maybe using the values from that sensor to home or to check and retract the ram at LinuxCNC start?
Also use the value from that sensor to stop the machine from moving anything else if not in upper position. I would strictly tie this to motion feed hold if this is punch press so the part can not move until the ram is up. This i think is a must on such machines. Also to make sure the material has stopped before ramming down...

Getting a Hunk #1-9 succeeded, and a few lines later (right after trace.c) a HUNK #1 failed during the patch. 

install and kernel activation does seem to complete if it’s ignored. 

Is the cylinder controlled by -10 volts advances and +10 volts retracted position 0 volts gradually descends
Note: I am using translate google sorry for any inconvenience

Thanks for the feedback, good suggestion, but since I'm very late on this project, physically installing a sensor will take more time and I don't know if the client will accept it on the next visit. Your idea helped me to try a different way, maybe never tried before in LinuxCNC, which would be to take the analog voltage reading from the inductive sensor that is present and already part of the original machine and create a logical ladder to compare the voltage from zero to 10V where 8.6 volts would be the virtual limit switch. With your experience, do you think it is possible to use an analog reading and determine certain thresholds to turn on and off a bit memory in the ladder and use it as a limit switch?

Found my issue. The internal encoder parameter is not getting set properly on the 7041's In my XML config file I have the encoder modparm set to false but when i open a terminal after axis has started up and check the parameter using "ethercat -p upload --type uint8 0x8012 0x08" it shows it as zero instead of 1. I suspect something in the driver code is not jiving with the revision of the modules i have. When I set the parameter manually after axis has opened up. The simulated encoder feedback is updated on the pins as it should be and all is well.

Is the cylinder controlled by +-10V or just 0-10V?

Is it setup as a normal axis?
Adding a switch and using it for homing would work in that case.
Adding the switch would be advisable in any case and set it in hal so it does not allow anything to move if the cylinder is not in the upper position.

None of us know anything about Parallels. People have succesfully installed Linuxcnc on apple hardware from an ISO but the machine no longer runs macOS

You can't run a CNC machine from a VM because it requires a real time operating system (eg runs PREEMPT_RT kernel) 
For testing and experimenting, I would install Debian 13 (aka Trixie) using a CD ISO from cdimage.debian.org/cdimage/weekly-builds/
Drilling down to AMD64 cd-iso, it looks like there is a Mac version
cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/

Be sure you are connected to a wired internet connection before running the installer
When installing Debian, ensure you install the XFCE or mate desktop (our ISO uses XFCE)
to install Linuxcnc then all you have to do is type:
 

This time you can blame it on me as if i recall correctly, Parallels is the software running on Apple hardware and makes it possible to run other operating systems in it, in short running virtual machines.
If that is correct, then all my answers are on point, it should run any ISO without making images on other hardware, that is the whole point of it.
Then again, it is Apple, so maybe only runs ARM stuff?

Thank you for your response.
Yes, you are correct. The position feedback should function properly as long as LinuxCNC is running, so I just need to set the position to retract the head at the end of the G-code, and the initial Z position should be in the retracted state.
However, when starting the machine, the process must be done manually to ensure that the Z-axis is retracted, preventing a potential mechanical issue where the Z-axis could be extended and collide with the punches.
How can I ensure that the Z-axis is retracted before executing the G-code program?

And please mention which model of the Lichuan servo and servo drive you use.
I assume they are cia402 devices. Here is a link to the cia402 component with a minimal example how to set it up.

Found another one.
The slider for max velocity is working incorrect.

As one can see, I test stupid high velocities, accelerations, jerk values and so on. With such experiments I am able to crash the tp. But no freezes of linuxcnc and I am able to stop the program and restart it without a problem.
