This video of mine explains how to build Linuxcnc for a RIP (and Debs)

Ethercat install is here forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

But once you change the name, it should not matter if a user installed by the Debs. The .so just needs to be installed in the right folder. Perhaps that can be scripted too.

It will be interesting if your planner could be copied to the EMC folder src/emc/grotius_tp and the main make file modified to build it. I did this once for a seperate task module and it took about 15 minutes.

Easiest way is to grotius build an .iso file for greenhorns as me... but I think the best way to do it is to learn it myself but it is pain to everybody around included me who is something starting from scratch ... there it is a lot of stuff depends at a lot of other stuff ... I am starting them on my virtual machine but when it will work I will move to real iron .... I will need a little bit of help and patience too

Hi Endian,

Yeah. I know it's a pain.
But today i started building a new linux distro. I am at 50% now.
It will take some time.

Do you need additional software on the distro?

No basically not for me ... I am using only Geany, wine and lcnc + ethercat-master but others... If I am understand right what do you mean ... other stuff should be installed then

Hi Endian,

Geany & Wine are on the iso.

Hi,

The iso is based on : debian-live-12.10.0-amd64-lxqt.iso
This iso is unpacked, filesystem is updated :

new kernel : linux-image-6.1.0-32-rt-amd64 + headers.
codeberg.org/skynet/ethercat-master
codeberg.org/skynet/linuxcnc_scurve_compact
codeberg.org/skynet/linuxcnc-ethercat
codeberg.org/skynet/hal-cia402
+ qtcreator, wine, geany.
+ crontab install to find & set mac adress at startup for the ethercat bus.

Now this will take an hour or 2.
It's repacking the filesystem after it was modified in a chroot environment.
Working in a chroot environment feels a bit like hacking the guts out off linux.

Then repack back to .iso format.
Then test the iso by installing it on a old pc.
We will see what happens.

So far i made a LINUX_DISTRO.md file, to log the steps.

Hi,

Yesterday i was trying to install the new .iso but it failed. No kernel was found.
I noticed i made a mistake somewhere in the process. Brrrr.

Now after a while i noticed i had to copy some files inside the iso related to the rt kernel.
Then installed it again. This time the rt-kernel was found.

At the moment i added extra software and it's packing the filesystem. After that i will test the iso once again.
I am testing from 16gb usb to 16gb usb.
Then one usb contains the .iso. The other usb is working as hdd to install debian12rt on. This worked yesterday.
It's only a slow install process. It takes a long time.

We managed to borrow server space from our friends : QtPyVcp Team.

Here we can now host bigger iso files at : repository.qtpyvcp.com/linux-distro/
this link is now empty, but hopely later on this day, the first iso will appear.

Thanks to QtPyVcp Team.

Configuration software for Kollmorgen servo drivers are only for win7 and I do not want to use more PCs or virtual stuff on my lcnc ...

Tommy what any news with the servo stuff from your workshop? do you have any new pieces?

No, nothing new, it's been very quiet on the business side for quite some time so it's causing me huge mental stress after investing all that time and effort and money, but keeps me cool knowing i have plenty of stuff ready.
Just came from the old shop, was looking at starting to build a mill (finally) and a small lathe, and maybe if i can organize the rails and ballscrews a small wire EDM.
I have to much stuff that does not fit together nicely so i need to convince myself to grab the angle grinder and have a blast with it till stuff fits together!

As for servos, i still have some unused brushed motors, a huge brushless Siemens/whatever their name is, but no drives.
I do have plenty of RC servo drives, though, up to 8S/70A ones, but only small motors!

And to top it off in the "stuff that does not fit" i have analog RC googles but only digital RC camera!

@Tommy,

For your machines, you cut the steel plates for your machine's yourself and do hydraulic press bending the sheet metal too yourself?
What could be the reason the business is quiet?
