Umstieg von LinuxCNC + Mesa auf EtherCAT (Leadshine EL8 / Beckhoff) – Erfahrunge

Category: Deutsch

Das sind die A6-400EC 400 Watt EtherCat Treiber. Laufen mit einphasig 230V AC. Da die das cia402 Profil nutzen lassen die sich ganz normal mit LinuxCNC und der cia402 Komponente ansteuern. Beispiele für die ethercat-conf.xml gibts hier im Forum ja genug zu den A6 Treibern.

An sich stören mich die IOs der Treiber nicht aber ich finde das übersichtlicher/sauberer wenn alles auf die Beckhoff Module geht. Keine Lust da jetzt noch irgendwelche d-sub stecker zu löten für die Treiber. Habe durch mein Bedienpult nen haufen Digitalein- und ausgänge und mit den Beckhoff Modulen hab ich das schön sortiert.

Ich nutze die Treiber im inkrementalen Modus und referenziere nur über linuxcnc und nicht über den Treiber selber

Separating CiA402 Logic from EtherCAT (lcec): Modular Adapter + Drive Stub Valid

Category: EtherCAT

How about if we don't blame the drive for moving by itself during homing,
and instead make "motion" understand that it should follow the position feedback?

For several days now I’ve been getting the error “Motor 0 position error” whenever I try to move Motor 0 (X-axis). At the moment, only this motor is connected.The setup uses a DM556Y driver with a NEMA 23 motor.

I’ve attached the
.hal and [code].ini files.

I hope someone can help me figure this out.

thanks everyone :)

Still trying to learn exactly where in the code it fails.
It doesn't reconnect, that's for sure. If it had, it wouldn't have been an issue.
I overwrite the log and, alas, no saved useful log.
"Unfortunately" I didn't get a crash today when I worked with the machine.
I like the whb04b a lot.It's worth spending some time improving stability.

Running LinuxCNC on a Raspbery Pi5 using the Byte2Bot daughter board

Category: Installing LinuxCNC

I'm trying to set up the DB25 board to connect to a geckodrive G540 and running into some confusion. Currently reading the byte2bot guide on this and I'm confused about the hal_gpio pin naming. Where are these pin numbers for "pi5 2025" coming from?  They don't seem to match any pin mapping I've seen in any other online source. Do I use the 2023 or 2025 one? 

Image of pinout naming matrix below.

Hallo @nichtAlex, 

welche Treiber sind das von StepperOnline? 
Ich überlege, die A6-Serie (AC) zu nehmen, doch die von StepperOnline konnten mir nicht versichern, dass diese mit LinuxCNC funktionieren. Sie glauben es zwar, getestet haben sie es aber noch nie. 

Was mich noch interessieren würde: Was stört dich an den IOs der Motortreiber, sodass du sie nicht nutzen möchtest?
Hast du den Home-Eingang dann nicht in Benutzung? 
Sind das AC- oder DC-Motortreiber bei dir? 

Gruß Mücke

I think that's a good thought, however, I've found M19 is not available to directly remap according to this .
14.1. Existing codes which can be remapped
The current set of existing codes open to redefinition is:
Tx (Prepare)
M6 (Change tool)
M61 (Set tool number)
M0 (pause a running program temporarily)
M1 (pause a running program temporarily if the optional stop switch is on)
M60 (exchange pallet shuttles and then pause a running program temporarily)
S (set spindle speed)
F (set feed)

400V Servo (51 Nm) mit EtherCAT / CiA402 in LinuxCNC – bezahlbarer Drive gesucht

Category: Deutsch

Hallo zusammen,

ich möchte einen 400V Synchron-Servomotor in LinuxCNC über EtherCAT (CiA402) einbinden.

Ursprünglich war der Motor mit einem proprietären Encoder geplant, das habe ich jedoch verworfen.
Ich gehe nun davon aus, dass ein Standard-Drehgeber (z. B. Inkremental TTL/HTL oder BiSS) verbaut ist.

Der Drive muss also:
  • den Motor regeln (Drehmoment / Drehzahl / Position)
  • den Drehgeber auswerten
  • EtherCAT mit CiA402 unterstützen (CSP bevorzugt)

Motordaten:
  • Typ: 400V Synchron-Servo
  • Nennspannung: 400 V
  • Stillstandsdrehmoment: 51 Nm
  • Spitzenmoment: 120 Nm
  • Nenndrehzahl: 4500 rpm
  • Max. Strom: 122 A
  • Keine Haltebremse
  • Geber: Standard (kein proprietäres Protokoll)
Die Anwendung ist eine rotierende Achse mit Getriebe, keine hochdynamische Robotik.

Meine Frage:

Habt ihr eine Empfehlung für einen bezahlbaren EtherCAT-Drive mit CiA402, der:
  • 400V Klasse
  • ca. 50 Nm Dauer / 120 Nm Peak
  • Standardgeber (TTL oder BiSS)
  • sauber mit LinuxCNC (IgH + cia402.comp) läuft?
Der ursprüngliche Hersteller-Drive liegt bei ~4.000 €, das ist für mein Projekt zu hoch angesetzt.

Falls ich etwas übersehe:

Reicht es korrekt betrachtet aus, wenn der Drive:
  • den Motorstrom regelt
  • den Encoder auswertet
  • CiA402 unterstützt
Oder gibt es bei 400V-Servos noch typische Stolpersteine, die ich beachten sollte (z. B. Kommutierungsanforderungen, Encoderauflösung, Stromgrenzen etc.)?

Ich freue mich über konkrete Modell-Empfehlungen oder Erfahrungswerte mit LinuxCNC.

Viele Grüße
Mücke

Proposal to improve forum stability and structure

Category: Forum Questions

We are actually working on updating all the software now.

The downtime of the forum is due to DDOS attacks.

We actually have more control than I thought.

I was just in the garage using the mill with the pendant. And thought that maybe I should post a mood picture, so we don't forget why we put effort on improving the pendant software :)

Proposal to improve forum stability and structure

Category: Forum Questions

Hello JT,

It's a real shame that you don't have access everywhere.

Installing a Joomla + forum is not difficult in principle – the real challenge usually lies in maintenance and upkeep.

From what I've read so far, there are a few problems with the forum. Some functions do not work correctly or have been deactivated due to errors. In addition, the forum is often unavailable, which I find very unfortunate, as the community suffers as a result.

It may be possible to create a new folder under root and create a new database (the database software is already available). In this new environment, you could reinstall everything and set it up cleanly on a trial basis.

The new folder could be assigned a subdomain (e.g., forum-test.xyz.org). Everything could be installed and configured there at your leisure. Once everything is running smoothly and error-free, the subdomain could be adjusted accordingly and the old forum could be left as an archive – for reference and review.

I completely understand that your time is limited—we all feel the same way. Nevertheless, I would be delighted if we could find a solution together. This would certainly be very valuable for the community.

I would also set up a Joomla + forum myself, but I only have 5 GB of web storage—unfortunately, that's not enough. Therefore, it would make sense to implement it on your server.

Best regards
Mücke

Am I right in thinking you have battery-buffered encoders?Then you don't need homing.First remove the loops and see if the errors decrease. Dmesg requires admin rights.

@Aciera you should come play with the primary vtk display for qtpyvcp!! looks like you have sorted a good bit out, would love to have it native without needing a secondary add-in for simulation.
