Pretty sweet.


Nah that's really sweet. Wot it do ?

That would really require delving into the data sheets regarding the gpios, and how and if the Linuxcnc kernel exposed them, they might be available via sysfs. I have doubts about whether they would be realtime capable.
May libgpiod, but not at all sure.

I think someone may have raised suspicions many many months ago. But my memory isn't what is used........oh ok there's a monkey

Guys
I got the cable! just found one from when i got the 7i78 previously and never used it.

Thanks a lot for the availability to ship one out

How about the bit file, where can i find it? do i need any special firmware editing or something?

thanks

Boot the PC from it and run the tests in Live mode, meaning do not install, see if it hangs.

Literally what I said in my post before it "mysteriously" disappeared into thin air.

(no offense to you)

Sigh...

1. You literally repeated my already existing post
2. You linked the wrong ISO location for the same ISO
That can and will absolutely raise suspicion.

This is the only thing that works smoothly for me.

Haha no problem! Yes, I know I still have a lot to learn but I think I'm getting there in my own time. 
I won't bother with pics of floors, roofs or pipes but here's some metal I did earlier in 2019. I look forward to hearing where I'm going wrong!
Like a lot of people on here, I also have a day job - in my case power electronics product development that requires a fair bit of travel to Korea and Japan, in addition to time in the office each week away from home.

Valuable advice NWE, I will keep this in mind going forward.

I can confirm that the home function works. I made a connector from an old VGA cable and tested it on one axis.
Pin 13 <- 0V
Pin 8 <- Home switch (DI3)
Reference run method: 6
I am now waiting for the cables I ordered, and then I can test and complete the other axes.
Note 1:
The DI status (U40.04) is contradictory.
The inputs do not show as switched high.
When they are activated, they go low.
The driver interprets a low as 1, which is confusing.

Note 2:

There may be a problem with cia402homecomp.comp.
Once it has started, it cannot be stopped.
This happens, for example, when the servo moves to a limit switch.
It is not possible to move freely; the error “Home movement is still active” occurs.
This error also occurs when only one axis is referenced.
After completing the home movement, it is displayed as referenced, but can no longer be moved. The error “Home movement still active” also appears here. I will see how it behaves when I perform the home movement on all axes.

Note 3:

Since recently, I have been getting an amplifier error on the Y-axes (gantry) when starting Linuxcnc (gmocappy). The error can be acknowledged and does not reappear during runtime. 
However, this may have another cause.
 

Thank you very much, you are great.

net rro-count <= [HMOT](CARD0).7i73.0.0.enc3.count

# verbinde max Geschwindigkeit Neufestetzung Inkrement - MPG (connect max velocity override increments - MPG)

setp halui.rapid.rapid-override.direct-value false
setp halui.rapid.rapid-override.scale 0.666667
setp halui.rapid.rapid-override.count-enable true
net rro-count => halui.rapid.rapid-override.counts

Is that correct? Does PNCCONF need to be adjusted? Does MESA CT use the new values?
 

Note
For GMOCCAPY 3 some HAL pin names have changed when new controls have been implemented. Max velocity does not exist any more, it was replaced by rapid override due to the demand of many users.

For the record, don't repeat the mistake I made a while back. I mounted the encoder inside the belt drive housing to some shaft driven by gearbelt. If I remember right I used a hal mux switch to select encoder scale according to backgear position. It all worked pretty good, but foiled all attempts at tapping because the encoder was not at a 1:1 ratio to the spindle. I think the big problem was index changed with each spindle revolution.

I figure it would have worked better to drive the encoder at a 1:1 ratio with the actual spindle.

I explain above that with every settings off the difference is about 5000-7000
Edit: Anyone know how to use gpio on the board?

Edit 2: i really hate this style off editing of the forum. 

I used last night the iso from youre post
www.forum.linuxcnc.org/9-installing-linu...-rtai-and-rt?start=0

Linux Mint 19.2 with the bios settings off (single core) RTai
Run it like 2 hours and it never froze.
And the latency was about 12000
