thank you very much
i loaded the new firmware and everything works.
in the folder that i downloaded from the official mesanet site i saw that there are many .bit files
is there a way to know what the various configurations do?
i searched around a bit but i didn't find anything...
ciao

Which kernel version is best for real time? was created by DarkPhoinix

Which kernel version is best for real time?

Category: General LinuxCNC Questions

I tried several times even asking for help to solve the latency problems even by changing the video card.
I opened a post here:
forum.linuxcnc.org/38-general-linuxcnc-q...st-ambiguous-results
So I decided to do it my way and not Debian's way.
www.kernel.org/
I have always used Debian but as always this time I will have to compile the kernel by hand, hoping that there are not too many changes since the last time I did it, but I doubt it.

Can anyone please tell me which kernel is best for RT?
Thanks a lot.

Can I have 2 seperate interfaces on the same computer? was created by Catch22

Can I have 2 seperate interfaces on the same computer?

Category: General LinuxCNC Questions

Hello Everyone,
I have a question about using 2 interfaces on the same computer.
Right now I have my milling machine and it works on is axis 2.8.2 running on linux mint 19.3
But I really want to try Probe Basic but I don't want to ruin whats already working, can I
Install the latest version of Linuxcnc and Probe Basic and go back and forth between the two
to see if I can get it working on Probe Basic without deleting axis 2.8.2?
Thanks Mike

Not as it is. It would have to be added to this part of the code (unfortunately I'm rather busy with other things right now):

You can read the current firmware pinout and change the installed firmware with mesaflash

something like:

sudo mesaflash --device 7i90hd --epp --addr 0x378 --readhmid

To read the currents firmwares pinout.

or

sudo mesaflash --device 7i90hd --epp --addr 0x378 --write 7i90_epp_svst8_12_2x7i47.bit

To change the firmware to 7i90_epp_svst8_12_2x7i47.bit

I've tried everything:
in the ini I put:
#SERVO_PERIOD = 1000000
SERVO_PERIOD = 2600000
#SERVO_PERIOD =  700000
#SERVO_PERIOD =  777777
#SERVO_PERIOD = 1000000
kernel parameters:
#GRUB_CMDLINE_LINUX_DEFAULT="quiet isolcpus=2,3 r8168.EEE=0 pcie_aspm=off nohz_full=2,3 acpi_irq_nobalance noirqbalance irqaffinity=0 processor.max_cstate=0 intel_idle.max_cstate=1"

#WORKS WELL#GRUB_CMDLINE_LINUX_DEFAULT="quiet isolcpus=2,3 r8168.EEE=0 pcie_aspm=off nohz_full=2,3"

it doesn't work, I get improvements and delays in the error but while using YouTube sooner or later the job fails.
I'm understanding that LinuxCNC only works with specific hardware systems and it's not possible to use it everywhere. I have also tried 3 completely different hardware setups, and the other 2 have impressive latencies.
One of which is new hardware with integrated video card, Alder Lake N95 CPU, and 16GB of RAM.
So the question is: what hardware supports LinuxCNC? What hardware should a user buy who wants to use LinuxCNC?

mesa 7i90hd

Category: Driver Boards

hi everyone
after a long time i turned my cnc back on.
the 7i43 that was installed above after a few days shows no signs of life.
no big deal i have a 7i90hd bought many years ago in a drawer.
i make changes to the wiring, because the stepper outputs of the 7i90hd do not match those of the 7i43. with pncconf i put, on the pins that were left free in the same connector, all the various IO functions.
i start linuxcnc and all the various functions work but the step generation does not work.
the interface card between the 7i90hd and the outside world is a 7i42TA and with the 7i43 it worked perfectly.
i mounted the 7i90 as i bought it; I've had it for many years and I don't remember if I tried to modify the firmware then... and in any case I put it in a drawer because there was no option in pncconf and I couldn't configure it manually.
the firmware version that pncconf gives me is SVST1_4_2x7i47s.
what could have happened?
do I have a faulty firmware?
how can I fix it?
ciao
Roberto

Category: Gmoccapy

Hi, I'd like to ask if I'm the only one experiencing this issue, or if it's a general issue with the Gmoccapy GUI?
When I perform a fresh installation on a virtual machine, I get the same behavior. So I assume it's a general bug in the Gmoccapy GUI.
Please let me know your experience... Thanks

Hi Pcw,

Its still this one : codeberg.org/skynet/linuxcnc_scurve_compact

I did a forced upload yesterday, resulting the git history is whiped out.
Otherwise maybe to be sure : git clone --recurse-submodules codeberg.org/skynet/linuxcnc_scurve_compact

If you see the new hal pins appearing, it's ok.

I really hope you can run a few motions.

Moving from Axis to QtDragon?

Category: Qtvcp

Just one approach is to find a setup you like among the linuxcnc example and take a copy of that.
Copy your ini and hal file over those files.
Change the DISPLAY line in the ini file to
DISPLAY = qtvcp  qtdragon
and there is a good chance it starts up. A starting point.

I guess you installed ethercat-dkms, the modules seem to be generated a couple of days ago.
It works now?
If it doesn't I would say to reinstall ethercat master and the drivers
sudo apt remove ethercat-master ethercat-dkms
sudo apt install ethercat-master ethercat-dkms
# edit /etc/ethercat.conf again
and make sure that the rather lengthy part where the modules are being built for the kernel succeeds.
