So 10 - 13 match with 30 - 33, 17 -> 24, Estop -> 20.
Is there a guide for this? I.ve looked HARD and found nothing. The PnCconf docs skip right over this.

If you want to delete the TEST sections, either don't delete
this part, or delete it and uncomment the commented out section
above (since they are duplicates)

Should also get rid of the TEST part completely, left side of pin names are just pin names (non existing ones that you created) so they will do nothing as they are.
So you will most probably need to uncoment all the listed stuff from PCW, for all joints/axis.

What we need is a way to "link" the two joints (example: X and X-slave)... Am I correct, currently we tell both to home and just expect them to go?

If one isn't ready, or simply fails to move, we would prevent both from moving.

What if CIA402 component had some pin, maybe an io pin to monitor, and any drive connected to it could set it, causing them all to halt?

net gantry-halt-interlock   <=> J1.cia402.halt
net gantry-halt-interlock   <=> J2.cia402.halt
If a drive is commanded to move, try clearing the pin just once. If a drive is faulted and sees this pin got cleared, set it again.

Or maybe a better way, (or additionally?) monitor both joint positions, if the difference exceeds some value, stop both?

Just throwing the idea out there. Maybe I'm just making noise.

There are many missing connections in the hal file:

As a start I would uncomment the high-lighted commands
##net x-index-enable <=> pid.x.index-enable
##net x-enable => pid.x.enable
##net x-pos-cmd => pid.x.command
##net x-pos-fb => pid.x.feedback
##net x-output <= pid.x.output

##################TEST#############################
# joint-0 enable chain
net joint-0-index-enable <=> pid.x.index-enable

net joint-0-enable <= joint.0.amp-enable-out
net joint-0-enable => pid.x.enable
net joint-0-enable => hm2_7i97.0.pwmgen.00.enable

What do you suggest?
Creating a new .hal file?

From your hal file:

Looks like a chemically castrated hal file, so what am i missing as that can not work.

Hey mark 
From memory no the run away doesn’t happen when I disconnect the axis from the masa board. Which may mean I should be able to use f2 to latch the relay!! Will try this.

yes I have the manual  and I haven’t done this as the drives were working perfectly before the controller died.  

You hardly have a close up of your 7i77?

Just to clarify I should be connecting the differential inputs E1 and E2 to Aout0 and Gnd?

What you are expected to do is for example:

Setup the number of stepgens and pwmgens and encoders you need:

 

Then select which axis are connected to which stepgens etc:

Intéressant, testez si pin 1 (et n'importe quelle entre 10 et 17) fonctionne comme entrée. Dans ce cas, la carte fonctionne en mode X (j'utilise ce mode fréquemment).
C'est rare, mais j'avais une carte double port qui ne fonctionnait que comme ça, si un seul port était configuré.

Replied by NWE on topic current latest download of LinuxCNC V2.9.8 will not install GRUB on several PC's

I didn’t spot it in the bios but equally wasn’t looking for it. Is it normally in the same area of the bios screen that legacy mode and secure boot reside ?

 
That sounds like it... Trusted computing. Boot priority. Those are some areas I'd think of checking. If it is nowhere, then it probably does not have CSM.

One naughty bios in one of my systems a while back showed: CSM = disabled. It could not be enabled. The manual said it can be enabled if you install a graphics card. I tried that and it worked. Which was a problem because it had only one PCIe slot and I wanted something else in it; I had no need for a graphics card on that system.

We created a file using the proconf Wizard.
We compared it to ours because ours was created with an older version.
We noticed some differences.
Then we imported the differing lines into our HAL file, which successfully removed the errors, but the axes still move slowly automatically.
In the HAL file, we marked the sections we took from the other configuration with #####Test######
Items we commented out are marked with two ##.

Can’t find anything in the bios related to csm
Not all bios seem to have that.

If bios has CSM and it is turned off, I have no luck booting anything in legacy bios mode, I get:
"No boot media found"

My hazy memory is slowly refreshing. It seems I manually created a small bios boot partition (legacy mode) or efi partition (uefi mode). I never investigated why I had to do that; whether:
1. The automatic partitioner failed to create it, or
2. Some option I had selected prevented it from creating it automatically.

Posting a screenshot of what it is creating at the stage it asks you to confirm the partitioning might be helpful. I'm not sure whether there is an easy way to take a real screenshot of that, you might have to snap a photo of it.

Unterstützung bei LinuxCNC + EtherCAT + Servos gesucht (Raum Stuttgart / Remote, was created by Muecke
Hallo zusammen,

ich suche Unterstützung beim Aufbau und der Inbetriebnahme eines LinuxCNC-Systems – nicht nur ehrenamtlich, sondern gerne auch gegen Bezahlung (€).

Kurz zu meinem aktuellen Stand:
Ich habe bereits ein 4-Achs-System aufgebaut (ohne Spindel), betrieben mit Mesa-Hardware und Schrittmotoren. Das System läuft grundsätzlich, jetzt möchte ich jedoch eine Nummer größer planen und perspektivisch auf EtherCAT mit Servomotoren umsteigen.

Je mehr ich mich allerdings einlese und anschaue, desto klarer wird mir, dass ich das wahrscheinlich nicht komplett alleine sauber umgesetzt bekomme. Daher suche ich jemanden, der mich beim Konfigurieren und der Inbetriebnahme von LinuxCNC mit EtherCAT-Servos unterstützt.

Geplanter Ablauf:
  • Aktuell bin ich noch bei der Auslegung der Motoren und der Auswahl der passenden Servoregler
  • Sobald die Hardware da ist, möchte ich zunächst ein Testsystem am Desktop aufsetzen
  • Ziel ist:
    • Motoren, Endschalter und Homing-Schalter korrekt in LinuxCNC einbinden
    • Eine saubere Dokumentation, wie die Motoren später kalibriert werden müssen
    • Sicherstellen, dass die Verfahrwege exakt stimmen, sobald die Mechanik fertig ist

Der Zeitrahmen für das Projekt liegt bei ca. 3–6 Monaten.

Örtlich & Zusammenarbeit:
Ich komme aus dem Großraum Stuttgart.
  • Bei Nähe: Gerne persönliche Zusammenarbeit, Hardware kann ich bei Bedarf vorbeibringen
  • Bei größerer Entfernung: Remote-Setup ist für mich völlig okay (VPN / Remote-Zugriff auf den Linux-Rechner + Videoübertragung)

Aktuell ins Auge gefasste Anbieter (EtherCAT-Servos):
Meine Frage an euch:
  • Hat jemand Lust und Zeit, mich bei diesem Projekt zu unterstützen?
  • Oder könnt ihr mir jemanden empfehlen, der Erfahrung mit LinuxCNC + EtherCAT + Servos hat?

Ich freue mich über jede Rückmeldung.

Viele Grüße
Muecke
