Thank you for your help in advance, I have tried to reinstall ethercat master and trying to disable eoe, but its getting worse with the ethercat service can't start. I hope I can continue to update when it works with onceloved's help

ooh, thanks

ill look at this when i wake up. im burned out from trying to make chatgpt give me something useful haha

Probably invented hot water, again!

Hallo miteinander,ich konnte keine vernünftigen Datenblätter für diesen Antrieb irgendwo finden.Schade denn ich hätte diesen Antrieb gut gebrauchen können. Jetzt habe ich Plan B umgesetzt.Wenigstens konnte ich das Getriebe retten, ich habe ein Adapter gebaut und wie ihr seht ein JMC Servo verbaut.Im Anhang findet ihr ein Bild.Vielen Dank an alle die das gelesen haben.Viele Grüße.

This is what Ethercat master documentation says
 

Two places to modify

Read out the sii info with "ethercat -p 0 sii_read"

1. Supported mailbox protocols.
Like it says in the figure, word 0x1C byte 0x38, bit 0x02 specifies EoE support.
Clear that bit for no support.
To orient yourself, you should find bit 3, 0x04, set for CoE support.

2. Enabled EoE mailboxes.

To find the byte that specifies drive EoE mailbox enabled:

In the read sii file, use some kind of hex editor.
Skip 0x80 bytes forward over the hardware config info
Byte 0x80-0x81 is 0x1a00 meaning strings section
Byte 0x82-0x83 is a word specifying the length of the string section.
  Example : 0xd100 = 209(dec) words.
  Add 1 to make it even: 210 words.
  Multiply by 2 to make number of bytes: 420.
  Add two for the size of the 0x1a00 identifier word: 422
  Sum up 128 + 422 = 550. Hex 0x226
At bytes 0x226-0x227 one finds 0x1e00 meaning general information section
0x228-0x229 is a word specifying the length of the general section
EoE mailbox specifier is now byte 9 in this section: 0x231 
To orient yourself, byte 8 (0x230) is FoE mailbox specifier, CoE details are in byte 7, (0x22f)

To disable EoE, first verify that the specified byte is 1. Then, write a zero in that position.


Upload the modified sii file to the drive again with "ethercat -p n sii_write mod_eeprom"

Personally, I wouldn't do this. I would use a Ethercat master with EoE disabled.

The above is only theoretical and may be wrong. Don't use it.


 

I haven't had a chance to really give it a good go lately, other things have got in the way.
But I've found your project to be solid and though it doesn't really relate to your project, but when I came across it I was in a bit of a dark place and it gave me the will and drive to get active again.

Here are the general signals that was generated for me by pncconf some years ago.You would need at least the enable and one of the vel-cmds.
Maybe forward/reverse and so on.
They all connect to the spindle pins (created by the motmod component).
Speed feedback is optional but nice to have, at-speed if your spindle can do that.
 

I'm civil/builder/construction labourer, using the page I linked to I was able to create Mesa bitfiles (then some custom ones for a clone board I made).

What it comes down to is being able to follow instructions.

A small request to everyone who uses Rio.

I hate telemetry in software, I don't want it in other software and I don't build it into mine either!

The downside, however, is that I never know if the stuff is any use at all.

I'm always happy when someone writes here that they've built a custom board, or when I happen to see pictures or videos online of boards I don't know yet.

An open source programmer usually only sees the problems and errors that users have, but very rarely reports of success.

So I would be very happy if you could give me a little feedback.

And even those who don't use it can say what they think is missing or what is stopping them from trying it out.

Best regards, Olli

@Dave3891, but you can send me the files (pinouts + board-image),
than i can create one for you

Thanks !

not really, in 'riocore/files/pin*.py' are some helper scripts for me (dev-branch),
but yes, most i do by hand.

@all
---- WARNING --- parts of the dev-branch is not usable at this time,
i do some bigger changes for the joint/axis configuration

20 years ago I tried Linux CNC once, but I gave up due to language barriers and the European purchase restrictions of the cards.
I have built quite a few CNC machines in the past 40 years in systems running under Win.
Today's language translation programs can be an incredible help.
Clone cards are now available at a reasonable price, so I thought I would try the Linux world again.
The helpfulness that the Linux forum provides is amazing.
A special shout out to PCW for his help and expertise that he shares.
I am an electrical engineer and I can create an electrical circuit diagram in minutes. My limitations when it comes to PC programming are huge. I have been trying Linux for 2 weeks. I still have a lot of questions. Today I will upload the unique configuration I received from PCW to the 7I92 card.

  Hello everyone. Can anyone tell me why the set coil works like a regular relay, and does not remain on when the input signal disappears?
I tried sending %B0 to the internal relay. The result is the same.

thanks, friend request sent
