Thank you, Peter.
I did as you suggested and I was able to see the dio listed in halshow.
I spent all day trying to understand how to access and setup the inputs and outputs using the M64+ commands.
I think I figured it out after hours of frustration.
My issue was understanding the syntax of how the actual screw terminals of the 7I77 connected to the input of an MDI command of say M64 P4.
I needed to get my head around the random name that I had assigned to an output [ say Digital out 4], the terminal on the 7i77 ( that could be terminal 8..) and the call sign [say M64 P3] that i put into MDI . Understanding how to link them all together in hal to get a predictable result was a head-wreck.

Watching that single halshow dot finally turn from brown to yellow made my day.
Easy once you know.....as usual.

Thanks.

Having looked at this a few times, I think that the best place to do it is actually in a G-code filter. ie calculate the heading from the G-code and insert / append C axis moves as appropriate.

Actually, there is a use case that needs motion pins. A plasma cutter cutting bevels. An additional joint is needed to tilt the torch and there are complicated tilting torch holders that keep the torch tip axial to the Z axis (single axis bevel head). I was just chatting to a user with one who uses the post processor approach.

But picture a simpler torch holder design where the torch tip position moves when tilted. A component could take the bevel angle and calculate the offset x,y,z positions of the tilted torch tip and then apply external offsets to locate the torch on the cut path in real time. This way, the machine could consume simple 2D x,y gcode (which is the norm for plasma cutters) and enter plasma cutting nirvana with bevelled holes.

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.
github.com/LinuxCNC/linuxcnc/issues/3455#issue-3089348330

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.
