Ethercat random jitter fix

Category: EtherCAT

Thought I'd ask here. User has upgraded from Debian 10 to latest Debian 13.3 and 2.10pre RIP config. Now Running grandixximos Ethercat driver but have not set syncToRefClock yet.

He reports:
With the same xml file, i/o and drive configuration, Debian 10 kernel 4.19 with ethercat 1.5.2 works fine, it has no latency at boot and hasn't given any problems. The current system has kernel 6.12 with ethercat 1.6.9 and has synchronization problems at boot, sometimes it doesn't see some drives on the bus, I'm forced to turn it off and on again. Would it be possible to use the current 6.12 kernel and linuxcnc 2.10, with ethercat 1.5.2?

I copied the lcec_conf and lcec.so files into the respective bin and rtailib folders from the Debian 10 version that I have and which works well on my machines, with linuxcnc 2.9.0 pre1 and etherrcat 1.5.2. At boot time, the drives are now seen within 1-2 seconds of booting and are always found on the bus.

This has 5 axis servos and a few Beckhoff modules attached to EK1100 

Next step is to add syncToRefClock

It seems odd to me that today's Ethercat hal driver is not performing but rolling back to an older version of it works. It seems to me his problem is the driver, not the version of Ethercat.

Any ideas or advice?

Mesa 7I76EU TB2 not working right (TB3 works fine) – need help diagnosing

Category: Driver Boards

Unless you changed the firmware, I doubt that that's the issue.
 (all cards are tested and shipped with standard firmware)

You think it's worth it to give it another shot with flashing another firmware before returning it or do you advice against that?

The hal and ini file look sane so I would guess its some kind of hardware issue.
 So the card should be returned for evaluation

Mesa 7I76EU TB2 not working right (TB3 works fine) – need help diagnosing

Category: Driver Boards

I tried on a Raspberry Pi 4 with image "image_2026-01-21-raspios-lcnc-2.9.8-trixie-arm64"
and on a Laptop with image "linuxcnc_2.9.8-amd64.hybrid"
and unfortunately i get the same results on both, with the simplest configs i can do, even in the test/tune tab in pnc wizard it acts the same way, Sorry guys i may be missing something really basic here, do you think it might be the firmware?

config name "GG" made on the laptop

probe basic lath to define a net spindle-index-en spindle.0.index-enable

Category: HAL

I am going to test this

net simulation-Zindex near.0.out => and2.0.in0
setp and2.0.in1 1
net index-logic-ok and2.0.out => tristate_bit.0.in

net spindle-index-en tristate_bit.0.out <=> spindle.0.index-enable

net spindle-index-en => tristate_bit.0.out-en

I hope this fix the Input-output connection signal form <=> spindle.0.index-enable

probe basic lath to define a net spindle-index-en spindle.0.index-enable

Category: HAL

Dear andypuch

I am using a Ethercat encoder input, I only encoder cont (4096) per revolution, and turn counts

so I derivate the encoder counts to get the speed
and I derivate the turn counts to get the the Z index

Everything is working less the line
net spindle-index-en and2.2.out => spindle.0.index-enable

I test it with the screen qtdragon and the same result error (no good for lathes, lack on axis representation)
and with the gcomcapy screen and the same result error

I guessing that I am doing something wrong with the variable declaration, If I comment that line i can manipulate the spindle.0.index-enable on halshow mean variable is not linked

but if I uncomment the line on my .hal I get the error of that variable was already linked.

any suggest?
because I been testing allot thing but I still not viable to hit the ball

and as long I can see, this is my last missing point for run G33 or G76 on may ethercat Logan lathe 1943 upgrade (well I hope so, I can say that, after make it works).

Thanks again for your help.  Almost there but a few glitches. The 4th Axis program opens; X,Y and Z axis move however Y will not home. A axis homes but shuts the program down when attempting to move it.  Some type of (following error)..
I added a hash tag to the 3 axis enable line as I was getting an error saying the pin was already attached to another signal. When I applied the hash tag the program opened up.

Would greatly appreciate your comments.  I'm sure you would see the errors much sooner than I would.  It's been quite a learning curve, something I knew I would have to do sooner or later.

thanks in advance

The topic was not updated for a long time. I was trying to get the servo drives work with LinuxCNC and at one point I decided to start from scratch. Now my configuration is with only one servo drive. I managed to get the homing on index pulse working to a certain extent. The problem is when the servo is far from the index pulse, LinuxCNC gives "joint 0 following error". The servo keeps moving but LinuxCNC is disabled. For a successful homing, the motor should close to the index pulse. What is causing the following error? I attached the configuration files. By the way, the homing components used is the standard "homemod".

The "sudo dmesg" command shows warnings about datagram unmatched, time out and slave sync. The tried writing to 1C12:001 and 1C13:001 from the command line but it returns an unknown error "SDO transfer aborted with code 0x06010003". Using the attaced .xml file, when reading 1C12:001 and 1C13:001 from command line, it returns that the PDO mapping is flexible.

Very weird symptoms...

Probably should be returned for evaluation

As last check on the software side, can you post you hal/ini files?

I rather suspected that was the correct way to do it. I'll work on it.

I've never experienced the lag/delay you described. My setup seems to respond instantly to the pendant.

I guess I'll give the ferrites a shot.

I know TP2 does not support G33.1 yet, I thought TP1 did but never tested, might have to do some work there, thanks for reporting, will try to patch it up soon
