No Thank You Very Much. Interesting none the less. 

What we currently have is STUPID FAST and high performance already. Unless a mysterious someone has a requirement for an hypersonic motion machine-tool, nobody here (in our star system anyway) will be able to ceiling the perf of RIO as-is on any parts/processes level. 

Not sure what you did but after updating the git today I'm clocking this x2 speed of what it was a few days ago. Used to be 2.5ms, now down to little more than a millisecond. Impressive stuff, Olivier. 

160890 == 0.16ms
all over 1ms would be to slow because we have 1Khz servo-thread

 

how many ppr encoder do you use?

Looks good, not sure about the delay

uugp,

Some flaky BIOSes/UEFI implementations don't play well with RTAI and there's not really anything to be done to fix it except use a different motherboard. The laptop I've been using for RTAI development causes panics too.

Gaming motherboards are the best IMO because of the flexibility and usually stable BIOS, especially ASUS (TUF, Prime, ROG, etc.)

Congratulations.
but, I am unlucky.

On RTAI kernel. can be installed and everything works fine, fresh Debain 12.6 and 2.92 or 2.93 and RTAI258 or RTAI279.
But,
Starting linuxcnc, freezes.
Running /usr/realtime*/testsuite/run test, freezes.

btw, usapce work well on Debain with RT kernel.

7I97 + 7I85S config with Step/Dir index support on encoders 0..3
6 Encoders total (7I97 only)

 
 

try it with these numbers, I think this is what im using on one of mine. What I found with another user, was that this wasnt entirely deadband related.

Alternatively, there is a tuning program within the Axis Gui, under Machine menu called Calibration. you can manually adjust these numbers while running linuxcnc

linuxcnc.org/docs/devel/html/gui/axis.html#_menu_items

edit, in the other thread, why did you make your deadband a negative number?

DB25 pins 5,6,7,8 are step/dir pins on the common 5 Axis Mach BOB
The inputs are DB 25 pins 10,11,12,13,15

New install.
Did not want to say this often, but from experience i know playing with network manager and etc/network/interfaces file usually can not be recovered easily, as those are also tied to other networking stuff in Linux.

I have the same issue as you. Did you find a solution?

 PCW, Tommylight: I deleted the 10.10.10.1 gateway entry and the "IPV4 Addressierung". Both has no effect for the connections.
Chris(at)cnc: I tried your interfaces file - after restart I have no connections anymore.

So, I think I should give it up. I go with the status quo and start with manually configured connections as before, in network manager.
I would like to have a starter file on my desktop, with the ethtool line.
Can you help me to create that batch with sudo ethtool -C eno1 rx-usecs 0 ? I created a file called ethtool.sh, but I can't start it with double-click.
Then, I created a starter file with  Exec=konsole --hold -e bash /home/hanno/Schreibtisch/ethtool.sh but that doesn't work. I found that line in a forum posting but I dont have the slightest idea from that...

Thanks for all your help!
Hanno

And yet another post!! Because, well, I can and and and and because it's "LinuxCNC-RIO Week!!!"

Finally got my Riocore Gui desktop icon working. No more cmd/cli endless keyboard input required. Just double click desktop ico, change stuff, save, generate!!

Change Exec= /to your paths/, save file on your desktop as type "Riocore Gui.desktop"

My 5-axis bob is a HW-356 Mach3 bob (inexpensive chinese bob). Those pins correspond to opto isolated inputs. 

Can one of the step/gen pin be used for a RCPWM signal or perhaps the spindle PWM pin.

The frame ground on a 7I96/7I96S should connect to
the  earth ground. This is to protect the 7I96S from large
EMI/ static from the Ethernet connection. This is especially
important for noisy machines like plasma cutters.

The reason for the 5V and GND on the step/dir connectors
is to support single ended use. For single ended logic level
drives or drives with common cathode connected OPTOs,
you would typically use STEP+/DIR+ and GND. For drives
with common anode connected OPTOs, you would use
STEP-/DIR- and +5V
