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

Change Tool Offsets after editing the Tool Table

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.

Using POSIX realtime

Category: EtherCAT

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.

Mode and Scaling

Category: EtherCAT

1. Normally csp I would say. For a spindle motor csv.
2. I prefer to send position in machine units to cia402 and do the scaling closer to the drive. But that's just me.
3. lcec comes from here github.com/linuxcnc-ethercat/linuxcnc-ethercat and there is a link in there to a reference guide. Unfortunately it doesn't cover sdo uploads. But it's done like this. Example comes from one of my ect60 stepper motor drivers.

<slave idx="0" name="X" type="generic" vid="00000a88" pid="0a880002" configPdos="true">
      <dcConf assignActivate="300" sync0Cycle="*1" sync0Shift="0"/>
      <sdoConfig idx="2000" subIdx="0"><sdoDataRaw data ="a0 0f"/></sdoConfig>  <!-- Max motor current (3.0A=b80b 4.0=a00f 5.0=8813) Rated=4.0A -->
      <sdoConfig idx="2003" subIdx="0"><sdoDataRaw data ="64 00"/></sdoConfig>  <!-- Standby current percentage (100%) -->
      <sdoConfig idx="2011" subIdx="0"><sdoDataRaw data ="01 00"/></sdoConfig>  <!-- Closed loop -->
      <sdoConfig idx="2023" subIdx="1"><sdoDataRaw data ="a0 0f"/></sdoConfig>  <!-- Kp=4000 (def=2000) -->
      <syncManager idx="2" dir="out">

The sdoDataRaw has some quirks. First you must enter 4 bytes for a 32-bit variable, 2 bytes for 16 bit and 1 for 8 bit.
Note the byte order, 4000 which is hex 0x0fa0 is entered as "a0 0f". 100 (hex 0x64) is entered as "64 00",

You don't set open loop in linuxcnc. You set it to cia402 csp (cyclic synchronous position) mode and it is up to the drive to figure out how to come to the position you tell it. In open loop the driver will just report back the target position, not the actual position as the actual position well that's obvious I guess.
If you need to set the sdo value during startup you can do that like this (example from my ect60 drive)

   <dcConf assignActivate="300" sync0Cycle="*1" sync0Shift="0"/>
      <sdoConfig idx="2000" subIdx="0"><sdoDataRaw data ="a0 0f"/></sdoConfig>  <!-- Max motor current (3.0A=b80b 4.0=a00f 5.0=8813) Rated=4.0A -->
      <sdoConfig idx="2003" subIdx="0"><sdoDataRaw data ="64 00"/></sdoConfig>  <!-- Standby current percentage (100%) -->

Note the byte order, 4000 which is hex x0fa0 is entered as "a0 0f"
