Just in case, does it work with CSM enabled? And secure boot disabled, of course.

Yes, the 7I76+7I77 firmware is not common so I don't think that there
is standard 7I76+7I77 firmware that include a PWM generator

Do you have a free step/dir output on the 7I76? (that would be the easiest place to add a PWM output)

What 5I25 connector does the 7I76 connect to?

 

Selbst schuld wenn man so was nutzt

ich denke mal, das die liebe KI dir unsichtbare sonderzeichen in den text gehauen hat, nur ne vermutung

I also just tried using Rufus in ISOhybrid mode, and DD mode, and Etcher. Even used three brand new USB drives (I have loads of these things where I bought out a local retailer and use them for students)

None of the liveUSB systems were able to completely install the system, and all of them failed at the "installing grub" step. Sometimes they would fail halfway through the "installing system" step.

CSM boot is disabled to force EFI boot, and I've even tried accepting all the defaults during the installer. No luck, and no matter what i do I can not get the installer to accept the realtek-firmware.deb package so I can get network access during the install.

I'm even using a recommended motherboard/CPU combination, the ASrock J3455-itx, and a Sandisk 140GB SSD.

Seems like a cool project but not really relevant. My tool manager is just a plugin for the QtDragon screen to manage metadata for the linuxcnc tool table. It is not concerned with synchronizing other tool table formats, though if it did, I think Fusion360 and Vectric databases would be good candidates.

One output, but three resistors...

Unlike sserial pins, you can only "setp"  sserial parameters (like the source and sink masks) in LinuxCNCs hal file,
they cannot be  changed dynamically. This is true of all sserial parameters, that is, they are only updated on driver startup.

The output modes are something typically set to match the interfaced hardware, so do not need to be changed dynamically.

 

Installed the latter. So far so good, didnt do any major tests but multiple power cycles. Also, with the ClockSyncCycles set to 5 and syncToRefClock=true, my servos are now instantly OP. no waiting for them to be ready which caused some amplifier errors when i was too quick with the power button recently.

no idea if thats because of the new linuxcnc-ethercat version or because of those parameters.

one thing to note though, the dc-phased pin never went high for me.

Hallo zusammen,

hatte jemand von euch schon mal dieses Problem?

Ich bin noch recht neu im CNC-Bereich und kenne LinuxCNC (MiniMill 2.9) noch nicht so lange. Ich brauchte eine Aufwärmroutine für meine Maschine und habe daher mithilfe von AI eine Datei generiert.
Ich habe den Code in meinen Windows-Editor importiert und die Datei als <Name>.ngc gespeichert.
Ich hatte zuvor selbst kürzere G-Code-Dateien geschrieben, gespeichert, auf die Maschine übertragen und geöffnet: Sie funktionierten sofort.

Als ich jedoch versuchte, den G-Code mit den von AI generierten Teilen zu öffnen, waren die Zeichen im Code völlig verstümmelt – der gesamte Code war unlesbar!

Als ich die Datei mit dem „gedit“-Editor unter Linux öffnete, sah alles einwandfrei aus.

Hat jemand Ideen, Tipps oder Lösungen?

Viele Grüße

Freddie

Gotcha. i will try to get this (github.com/linuxcnc-ethercat/linuxcnc-et...84ef36b53f0b734eaedf) installed first, with syncToRefClock=true and ClockSyncCycles set to 5 to see if my jitter issues go away. they are very random as of right now.

Or should i use this patch with the settings above?

Perfect, thanks

thank you,

I have custom PyVCP on right side of Axis. Will I need rewrite this panel is the case I will move to QtVCP or gmoccary?

Yes you can use just one output

Hello all, I am trying to configure `output_sink` and `output_source` pins for my Mesa 7i76eu and I am running into some surprising behavior. My goal is to put `hm2_7i76e.0.7i76.0.0.output-11` into sink mode. 

Long story short, putting `setp hm2_7i76e.0.7i76.0.0.output_source 0x0000F7FF` and `setp hm2_7i76e.0.7i76.0.0.output_sink   0x00000800` in my HAL file after loading `hm2_eth` does not seem to have any effect, output-11 remains in sourcing mode. I spent some time debugging this and found some surprising results.

The first thing I did was attempt to setup the pins manually without changing anything in my HAL file. For this test, my HAL file did not set `output_sink` or `output_source` at all. On a fresh power cycle of both my computer and the mesa card, the following works correctly (causes output-11 to sink when TRUE).

```
halcmd setp hm2_7i76e.0.7i76.0.0.output_source 0x0000F7FF
halcmd setp hm2_7i76e.0.7i76.0.0.output_sink   0x00000800
halcmd setp hm2_7i76e.0.7i76.0.0.output-11     TRUE
```

I can toggle output-11 back and forth between TRUE and FALSE and it appears to work just fine. The strange part is that if I set output_source = 0x0000FFFF output_sink   = 0x00000000 (going back to the default value), `output-11` remains in sinking mode, it does not switch back to sourcing mode. The only way I can get it to switch back is if I power cycle the Mesa card.

The second thing I tried was setting `hm2_7i76e.0.7i76.0.0.output_source 0x0000F7FF` and `setp hm2_7i76e.0.7i76.0.0.output_sink   0x00000800` as part of my postgui HAL, the thinking being that maybe there is some timing issue for when you configure the output pin modes. This does seem to work as long as I do a power cycle of the Mesa card and computer, but it feels like a bit of a hack.

I'm using this setup to control activation of a wireless probe receiver which needs `output-11` to sink to ground in order to activate the probe, so my main worry is that I'm just hiding a timing related issue by doing this in postgui and will end up running into a crash down the line. If anyone has some insight into how `output_source` and `output_sink` are supposed to work, that would be appreciated!

Thanks!
