I did a nother check in my BIOS and maybe i did annother improvement.
The ping performance looks mutch better then before.

Maybe this could solve the problem.
Fingers crossed...

I get 83 errors when I shut down linuxcnc, but they reset when it turn it back on. So a non issue, although would be good to know the why and fix it.

Also not I have not yet set up the IO on the drives.

Hey Tommy,

many thanks for your support.
At the moment i would like trying to solve it at this configuration.
The last 3 days i installed everything new (serveral times). with Probe basic, IRQ-Optimization, automatic tool probe.
At the moment everything works very well, only thisone problem.

Is there no way just use another driver or kernel?

Here some infos from ethtool.
Maybe there ist something, that could fix the problem.
 

Pulse generators are easy now, well not like piece of cake, but much easier than discreet stuff back in my days.
As far as i can recall it should have:
-adjustable voltage
-adjustable current
-adjustable ON/OFF time or PWM
-current feedback and limiting
-adjustable PWM frequency
All those can be easily done with any microcontroller, but might need better ADC converters.
Adding an output to it for sending signal to controller when short circuit occurs so the controller can back off should also be a couple lines of code.

If you do not need the latest features, you would probably be much better off by using the 2.8.4 ISO of LinuxCNC, and it is very easy to test if that works for you if you already have a working config:
-download 2.8.4 ISO from the downloads page
-burn to a USB
-boot the PC from said USB - do NOT install
-use file explorer to find the config on the internal drive
-make a copy of the configs folder to be safe
-open the copy of the config folder
-find the file that ends up in .ini
-right click on it, select open with
-near the bottom click on "use custom command" or similar
-type linuxcnc
-enter
That should run the machine as usual so you can check if it drops the link or errors out.
If that is successful you can install on internal hard drive.

Hello,

there are already some threads about this, but most of them never continued the topic or vanished. So I wanted to start another (that hopefully not has the same fate). The topic would be homemade sinker edm machine with a pulse generator. Is it possible? I just had some thoughts:

- Using the pulse generator based on Ben Flemings book (Build a pulse edm machine), but replace all the knobs and pots (if possible have not checked yet) with software and/or relais and control them via a gui.

- For simple jobs use a G1 Z-??? F??? and then somehow measure the spark gap and use motion.adaptive-feed to adjust it. The feedrate could be trial & error. Add a timer that every x seconds sets motion.adaptive-feed to -1 (or more than 1, have not tested that function yet) to lift the ram up and flush. Then use the spark gap value again to move down.

- With a XYZ(C) machine maybe even orbiting the electrode?

- Has anyone here build the Ben Fleming pulse generator?

Just trying to gather information before jumping deeper into this topic.

Thank you.

OK, after 2 hours of testing, the error appeares again...
Someone who can help me..

Best regards
Jens

I'd thought I'd add samba and windows can be a PITA to setup.
As the underlying OS is Debian bookworm, any guides or how-tos that cover installing samba on Debian will be far far better than asking here.
I would also install gvfs-backends and gvfs-fuse as well. Samba-vfs-modules might be an idea as well.

You only need the Ethercat repos if you are going to use Ethercat .

Thank you for the link.

I set up the software limits and homes. I assumed the hardware limits wouldn’t be necessary to get it running.

What I don’t understand at this point is how I get the gantry, which is currently at the midway point of the machine, 24” from the desired home location, jogged to the home location, in this software, so I *can* home it. I don’t see how wiring in the physical switches allows me to do that.

Hopefully the docs will get me there. Thanks.

Thanks. I’ll order the switches.

Having a blast is not my goal here. I need a working tool.

To be clear, when I set up the limit switches the software will treat the two Y motors as one? Currently they are being treated as separate axes, which makes it impossible to move the gantry to a home position.

hello, since there is no default configuration for 7i96s+7i77 in pnccfg, I'm trying to use mesact, but I get an error, I can't enter values ​​in the specified fields at all. thanks

Colleagues, does this apply for version 2.8.4?

Yes this is my goal, everything on a same board.
IC-NV part is not easy but one from PEdpex is working so I should use the same.
There is not much chip that can do this as good as IC-NV so I might stick to this one.
And STM32F4 works good for encoders so it should be a good match.
I will try to start from your E7000 then thank you

I want to install samba, but apt install samba gives "Package 'samba' has no installation candidate", I did apt update but it didn't help. I checked repositories and there is only linuxcnc.org. Should I have also Debian repositories or not? How to install samba?

Also do I need: "download.opensuse.org/repositories/science:/EtherLab/Debian_12/"? What is it for? It gives an error on apt update:
"Get:1 download.opensuse.org/repositories/science:/EtherLab/Debian_12 ./ InRelease [1,575 B]
