Hello
I'm a newbie. I started DIY Ethercat board with AX58100
1. AX58100-16in-16out
2. AX58100-Step/DIR + Encoder ABZ +8in/8out GPIO

Everything works on Twincat and I can connect it to Linux lcec

I want to use it with Linux CNC as 3axis and 1 spindle
In the axis there are
-Step/Direct
-Input8
-Output8
-Encoder ABZ
And there is AX58100-16in-16out board as the main I/O of the system

But I still can't create the correct ethercat-conf.xml file. I don't understand if it needs to be used as CIA402 or not
I have attached the XML files from AXIS for both boards

Can you please suggest a generator for ethercat-conf.xml for this project

Thanks for your support

 
 

The system does have brakes which I have disabled (the joint free drops when it gets the follow error)

it doesn’t have a physical counterbalance that I can tell, maybe the gearbox has some sort of clutch?  

When idle, the motors are able to hold the joint in place even if I push on it.

I have a feeling that there’s something off  between the motors and encoders.   When it moves, it seems to be miscalculating the actual vs expected travel - but that’s just gut feeling.   It sometimes errors moving up, but not always.. it always errors moving down.

Just add a VCP button, if you need it.

link to fdarling's sample code if you don't already have it by now.

Is there any way to create a button to select two different accelerations? example
my machine has an acceleration of 1000ms2 in the ini file, I want to create a button in the axis interface that when I press it changes the acceleration to 500, so I can work with heavy parts more smoothly without having to change it manually

First of all, my deepest deepest sympathies,sorry to hear you live in Melbourne, the only good thing Victoria has to other is Philip Island and the roads, airports and docks that lead out of the state.

Why aren't you using the premade image for your RPi ?

The links are on the Linuxcnc home page under downloads.

Please supply config files.

No the W5500 works, initiating (ip addrr and other such stuff) is done via the FPGA via the SPI interface.
You'll have to setup your config to use the W5500 so that the correct bitfile is generated.

Examples and docs are supplied on the github project page.

Remember "it doesn't" work isn't very helpful when trying to get help. Config files and such help. Remember this is not a trip to the dentist, we are not dentists and don't want to have to pull teeth to get information to help.

What does that exactly mean? How do you initiate the w5500?

Any reason for not using the ready made debs from the releases page?
github.com/NTULINUX/RTAI/releases
Or from here
linuxcnc.org/dists/bookworm/base/binary-amd64/
and the corresponding LinuxCNC build from here
linuxcnc.org/dists/bookworm/2.9-rt/binary-amd64/

I think I'm going to send it, because I found in the /usr/src/RTAI/ksrc/5.4.279 there are 4 .patch files that I think are what I needed.

Yeah, to many things missing and/or wrong there, or wrong config files.
Use StepConf wizard to make a new config and choose as shown in the attached picture:

This wouldn't happen to be what you are saying is it?

$ git clone /ksrc/patches/v5.4.279/"*.patch ; do patch -p1 < "${i}" ; done

So, now that I finally found time and access to a pc, I can share my .hal and .ini

I really appreciate any effort anyone puts into this.

Resolved issues by installing via dpkg from the Linuxcnc Downloads page rather than the Synaptic packages, ie followed the instructions above!

Max jitter on Dell Optiplex 980 i3 550 3.2GHz, 16GB ram, 512GB SSD, has dropped from c.60,000 using preemt rt to c.9800 using rtai with everything recommended disabled in BIOS.

So a good result.
