Hello Experts,

Is there any readymade package with LinuxOS+RTKernel+Ethercat Master prebuilt.?

Can someone please explain the core concept of Ethercat communication compared to traditional step and dir method?

I was wondering what parameters vary from machine to machine in terms of Ethercat configuration?

For example, I have seen that the Ethercat module needs the network card ID when installing/configuring Ethercat Master.
 

You have something called extrajoints, maybe that is what you are looking for?

Hopefully someone that knows how to work with carousels can jump in.

How is this sensor project going? I notice the product page still mentions out of stock. proma-elektronika.com/product/c2v-capitance-to-0-10v-converter/

I guess one way would be to loop back the commanded position to the feedback position
when homing, by using the mux2 component.

Normally you would do this in code  in your custom homing component (homecomp) or modify the cia402.comp

the HOME ini setting may help. linuxcnc.org/docs/stable/html/config/ini-homing.html#_home
It took me a long time for me to understand to use G54 Offsets to touch off at the origin to use for the gcode program.


 

Got it. Is there a main repo that is being worked on currently? I see there are a couple of repos out there.

Hello,

I changed the NVBRAKEONV and NVBRAKEOFFV settings a while ago on my 8i20 driver.  I would like to increase the voltage settings but I can't remember how to do it.  Also, searches in the Linuxcnc forum are giving me "401 Unauthorized" faults on a number of links where I would normally find the relevant information.  Any help would be greatly appreciated.

Regards,

It looks like we are using a 1024 bit long key (DSA1024) which is considered insecure by Trixie.
Ref: Google AI
Debian prefers a key length of 4096 bits for RSA OpenPGP keys used for signing, although Ed25519 is now the default for new keys generated with current tools, offering even stronger security.
While 2048-bit RSA keys are still considered secure for some applications, Debian's preference for 4096-bit keys is influenced by both security considerations and the desire to reduce future migration efforts for volunteers maintaining keyrings. This aims to combine potential future migrations from 2048 to 4096 bits into a single, proactive move.
When creating a new GPG key pair for signing Debian packages, you can specify the key type and length, with 4096-bit RSA or Ed25519 being the recommended choices.

and:
A dsa1024 key refers to a Digital Signature Algorithm (DSA) key with a length of 1024 bits, 
 

Have you checked that 'iocontrol.0.emc-enable-in' goes TRUE when you clear the external estop?

You don't need to worry about the position as its really automatic but if you do want to read the position the pins axis.L.pos-cmd is the commanded position for each axis.

Okay, thanks, that was easy. I haven't tested it on the machine yet, but it looks good.

In the tool table (gmoccapy), I can assign multiple tools to a pocket.
Can I check in the table that only one tool is assigned to each pocket?

my recommendation is to get it working in axis and then convert to gmocappy cos it does some funny things. If your config breaks on conversion, raise it with  gmocappy.

This is how I did it with a safety relay and an external latch button attached to the relay that
sends a signal to pin lcec.0.3.in-01 when the relay is enabled
this is inverted and sent to  the drives estop input on all drives.
The estop button is attached to the safety relay

github.com/rodw-au/vmnmillqt/blob/main/VMNmillQT.hal#L146

In this case no estop-latch is used,
