Just curious, is there a current developer forum, mailing list or discord server for asking technical LinuxCNC code questions? Is GitHub the best option?

Hey everyone... I really appreciate the fast replies! I've contacted Wayne and sent him this link... so I am certain he will get it running.

Thanks again!
Jerry

Hi,
Does anybody know what connector is used for the MPG of the NVUM4-SP Board.
Tried:
1)IDC 2x8
 2) 2,54mm Modu
3) JST
None of them fit.
 
 


They are 8x2 pins.

Thanks

Oh good, it's not just me!

You can do exactly that in youtube studio, there is a feature something like make short videos of your existing videos, i made one once testing it.

Hallo,
Du brauchst für den ersten Test keine confg in den NVEM zu spielen, die Basiskonfiguration für den Test ist dort bereits in der Firmware per default vorhanden. Zumindest bei mir war das so, sofern der NVEM antwortet (was er ja bei Dir auch tut) sollte das reichen. Die Fehlermeldung hatte ich auch, anfangs hatte ich da wahrscheinlich auch die falsche Firmware.
Ich habe dann testweise mal mit dem Oszilloskop die Achsausgänge kontrolliert, die liefern auch brav die Impulse.
Viel weiter bin ich allerdings auch noch nicht gekommen, es stehen und standen andere Dinge mit höherer Priorität an, daher sorry....

Gruß
Mario

@andrax
I appreciate your help and efforts on the topic. Actually, this was my working configuration, I just added the additional rows in .ini and .hal files as per you absolute encoder guide topic.

The "sdoConfig" line for 0x6098 is there to set the homing method of the drive. I added it before looking at your guide. It simply sets homing mode 34 - index pulse.

What do you mean by the wrong naming convention? You stated the halpin "opmode". Did I write it wrong or is the data type of signed 32 wrong? As per servo manual, it is an 8 bit variable but LinuxCNC expects it as signed 32.

I did not use the "name" attribute for the EtherCAT slave in the .xml, instead I use the slave ID number in the .hal file.

Would elaborate more on what is wrong the .xml file? I can get the .ini and .hal files from you absolute encoder tutorial but there is no .xml file there. That is why I ask about my errors in the .xml file.

Disable secure boot  in your BIOS.
I had this issue recently. I thought I had done this to this machine ages ago but, I found it was hard to make the change stick. Eventually got it. I found the numeric keypad is not enabled in the BIOS and used the top row.

Using name="x" is optional in the XML format and without it, it defaults to the slave number (which is great if your drives are the first slaves on the bus as it aligns with joint numbers). but names does free up the order of slaves. If following a template format, deviating from the supplied XML  can require a lot of editing as you are discovering....

Another delightful forum feature.

This:

iopl() failed: Operation not permitted

Must be fixed before proceeding.

You can ping without root privileges but The hm2_eth driver
must block other programs access to the interface and this
requires root privileges.

This is most likely a LinuxCNC install issue or perhaps a BIOS security
setup issue (secure boot etc)

I am still getting pings from the card.
But the delay is sometimes high.

I thing the network driver might be mixed up?
This PC has realtek 8125 Ethernet chip.

How do we check if there is any conflict between the drivers?

This sounds like a LinuxCNC installation issue:

iopl() failed: Operation not permitted

Konstatin, 
I don't understand why you don't stick with one configuration and keep trying different ones.
You already had working configurations, but you replaced them with new experiments.
I get the impression that you haven't read the important threads!

Your EtherCAT XML is full of errors again.
You have to give each drive a name so it can be assigned   name="X"

What are you trying to achieve with the following lines???
<sdoConfig idx="6098" subIdx="00">
<sdoDataRaw data="22 00"/>
</sdoConfig>
6098 refers to the homing method and is defined in the .ini file
CIA402_HOMING_ENABLED = 1
CIA402_HOMING_METHOD=4
CIA402_HOMING_SEARCH_VELOCITY=300000
CIA402_HOMING_LATCH_VELOCITY=100000
CIA402_HOMING_ACCELERATION=131072


A certain naming convention has been established here in the forum
With such naming conventions, you’ll confuse your fellow forum members and no one will be able to help you anymore.
halPin=“opmode” halType="s32"/>

You have to remember that the names you define in the XML must also be used in the .hal file.

I can only recommend one thing:
Delete all that junk!!!
Use the templates from the A6, and enter your VID and PID correctly.
Stick with this template and post any error messages!
 

   

Hello All,
I have an error after trying to set up a 7i76E with a Asus Essential 14 N150 NUC.
Running the latest Debian and installed Linux CNC as instructed by Mr Rod on his youtube video.
All the installation went smoothly, but i am facing this error during my connection to the card.This is my second install, I have previously set up a 7i96S system and is succesfully running.
I am running a 12V smps for the 7i76E board, could that could be a problem.I think I might have missed something here.Please find the error report attached.
Thank you,

Antony.
