Sorry.

Yes using level shifters, but if it works properly with the resistor just use that, it is OK.

Can you elaborate on this?

I found a situation with inductive sensors where default input threshold of 3.5 V is to low, as those sensors are 4.5-5.5 V in OFF state.
For one sensor I mitigated it with adding 10K pulldown resistor. Is there any better way to do that?

Tom I came across your videos looking for information on a Messer plasma table. I have an older machine year 2000 that I bought from a John Deere factory in Iowa that was running the day that I purchased it, I am trying to get it up and running but don't have software or the computer cables etc to fire it up. Everything is hooked up but its looking for a password. Has an older Navigator control that looks good but I cannot get past the password as I cannot type it in. I do know the password - i just cannot type it in. Messer is no help, they just keep saying it is obsolete. If you could point me in the right direction or be of any help I would greatly appreciate it. Thanks Sean

HI,
I wanted to share with you a tool I've built to make my life easier and I think it has reached enough maturity to be used as a real tool.
It is be no means perfect and some of it is not as polished as i wish it was, but I thought it'd be nice to have it reach more people.
The project's name is NoHAL and as the same suggests - it's supposed to make you not write HAL anymore.

https://github.com/b0czek/noHAL/blob/main/docs/public/screenshots/editor.png?raw=true

It does that by visualizing HAL network as node editor - with an added benefit of making repetitive parts of your HAL configuration templatable through sheets.
I've built it around what I work with, so it might not match your workflow perfectly but issues/pull requests are open for suggestions.
There is Mesa configuration utility built-in but I've only defined a limited set of boards - only those I have used.

Here's a link to repo with it:
github.com/b0czek/noHAL

And here's a guide I've written on how to use it:
b0czek.github.io/noHAL/

Please let me know what do you think of it.

Yes, Flex has full manual spindle controls for all 8 spindles. I'm working on updating the documents.

Just to prevent any search engine from finding incorrect information I deleted the posts with the incorrect information.

Thanks for all the hints.
And because I hate to abandon discussions out of nowhere, let me just say our family was hit with quite a tragedy and I can't say when there will be time and mental energy to get back to this project.

greetings mclien

I will do one last test with an Advantech Aimb 505 card with an i5-6700 processor. I tested the latency with Trixie and under stress it does not exceed 40 microseconds with a maximum delta of 2. I asked the customer if I could do this test and he will give me the machine available. Also because, now the only solution we are waiting for is a new version of Ethercat that is adapting Grandixximo?

A little preview of what’s coming soon.
This will soon allow you to create a board from the flow config,
or at least a template.

Has that bug been reported to the Devs?
 

Yes.

There's another spindle synchronization bug, possibly related, that I encountered at the same time last year.  @Aciera found a workaround for it, but I don't know if the two are related.
github.com/LinuxCNC/linuxcnc/issues/3556#issue-3398986003

I don't have the skills to really figure out what's causing the two problems, much less contribute to a fix.

EDIT - I somehow messed up pasting the forum links when I first reported the bug, but one can highlight the link and right-click to open the forum thread.

I've tried using qtdragon hal bridge function in every way possible, but it's not working. According to qtdragon documentation, if I understand correctly, if I define HALBRIDGE = hal_bridge
and also define a macro in the MDI_COMMAND_LIST in de INI file, qtdragon creates other pins that I can access through halbrdge , but these never appear in hal Show. I also understand that these pins related to the created macros can be accessed through external buttons, but unfortunately, there's no documentation on how to do this. In my configuration, I control some functions through external buttons connected to halbridge but for other functions, such as activating a macro, I can't, or I don't know how to, do it with halbridge.

Hi endian,thank you again. I made a completely clean test now with only the AX5125 connected on the EtherCAT bus, no other slaves connected.

I used your files from the zip exactly for the AX test. The startup initCmds file is your Antrieb-1-AX5-0-initCmds.xml unchanged. I only pointed my machine config to that file.

Current result is much better now:
the AX5125 reaches OP when it is the only slave on the bus.Current ethercat slaves output is:
0 0:0 OP + AX5125-0000-0216 EtherCAT Drive (SoE, 1 Ch.)

The important dmesg lines are these:
EtherCAT WARNING 0-0: Slave does not support changing the PDO mapping!
Currently mapped PDO entries: 0x0086:00/16 0x002F:00/32. Entries to map: 0x0086:01/16 0x002F:01/32 0x0024:01/32 0x0050:01/16 0x81E4:01/32 0x81E5:01/32EtherCAT WARNING 0-0: Slave does not support changing the PDO mapping!

So the situation now seems to be:
before, the drive stayed in PREOP plus ERROR with MBX_SOE.
now, with only the AX and your startup file, it reaches OP.
but the drive reports that its current mapped PDOs are still the smaller set with subindex 00, while the config wants the extended subindex 01 mapping.

My main question is:
is this already the expected next step, meaning I should now reduce the config to the fixed PDO set the drive actually reports as mapped, or is there still a missing startup/configuration step that should switch the AX5125 to the full 01 PDO mapping?
In other words: now that the drive reaches OP, what is the correct next step before I put the other slaves back on the bus?

Thanks a lot for your help. 

Ich sehe gerade, dass die Chinesen die Aliexpress Anzeige geändert haben und nun zwei verschiedene Karten in der Beschreibung sind. Keine Ahnung was man bekommt, wenn man die bestellt. Ich meine jedenfalls die hier.
