Wow, that is a sweet machine. It sure makes sense to modernise machines like that rather than converting manual machines. If the analog drivers still work, this could be a really simple retrofit. Like I did with my Maho. Not having to touch mechanical aspects of the machine can save you a ton of time getting it up and running.

How did Weiler do the home/end switches on this one? 

The EDA I'm forced to use at work is win11 based. I know I know...

However my entire dev environment aka compilers, IDEs, ect, are all Debian/linux based. No substitute

If you aren't friend with fine pitch then avoid the LV9QN88 part. Not much better than the ICE40UP5K to say the least. I'm with you though, prefer their LQFP pinouts...

Hi rodw, thanks for this hint. I havethis line in my hal file: Is that sufficient?loadrt hm2_eth board_ip="10.10.10.10"With the following settings the connection works at once:
 

My ping to 10.10.10.10:
 
What do you think about it?

THanks, Arno

Hi
waiting for a more suitable solution

I solved it almost like zylos146.

I searched and deleted all the ethercat-dkms folders, including the .deb

then I downloaded ethercat-stable-1.6 from
gitlab.com/etherlab.org/ethercat
followed the installation from install.md everything went well.

then I performed the standard installation here
it no longer returns errors
Hi

Not quite out of the woods. the changes were pushed to the LInuxcnc code on github.
I built a new image. The keys have been fixed but I am getting a dkms erorr so no joy.
I've updated the issue upstream, gitlab.com/etherlab.org/ethercat/-/issues/131
so hopefully  they will fix it soon. They have always beeen very good to me

WOW   very nice !!!
I recently tried to build a board with an ICE40UP5K, but I'm somehow too stupid to get it to work The FPGA chips are just too small for me to solder them by hand.

It would be cool to have a complete rio board without having to use a plug-on devboard .

I just saw that you use Windows, rio unfortunately only runs under linux, vm is also ok, if it works in WSL I can't say unfortunately

 

'trying to overwrite' errors indicate a conflict with another package.
This worked for me:

First contrib; Feel free to replicate/publish/flame/others. Great liltle working-but-simple fpga dev board.
Schematic attached. 

Do not enter a root password, if you do sudo is disabled and you won’t be able to complete the following steps

Interresting

I thought when I entered a password, I will be able to sudo

I don't know what to say, that was too kind Meister. Thank you so much for taking the time.

I'm working off a GW1N-LV9QN88 part (custom dev board). Schematic and pcb mostly inspired from the infamous TangNano9K and so I have a good feeling this won't be too difficult to port hardware-wise.

Let me set-up, clone, learn your work during the coming days. As soon as I have a successful IDE compile/project I'll share it with you to upload on your repo.

So excited about this already. Thank you again. I'll update progress!

jjdege .Thank you, I'll try to do that this evening, I hope to succeed

Do you happen to have LinuxCNC-RIO ported for the Gowin IDE? I'd like to explore your awesome work however would be willing to do so in an environment that I'm semi-familiar with already (i.e. Gowin IDE).

Thanks, yes gowin toolchain is supported, it even generates a project file for the IDE.
However, it is easier (at least for me) to work without an IDE, so you are not so tied to one manufacturer.
Since everything is more or less generated here, an IDE is only suitable for troubleshooting and playing around

for new projects, the best branch is here: 
github.com/multigcs/riocore/tree/dev

littlebee is not yet directly supported, but if there is a GW1N-9 on it, it should be no problem to use the TangNano9k configs as a template

copy the file: riocore/boards/TangNano9K.json to riocore/boards/LittleBee.json and edit it (type/family/clock-pin/speed), set toolchain to gowin

than copy riocore/configs/TangNano9K/config-uart.json to riocore/configs/LittleBee/config-uart.json and edit it (boardcfg and the pins / you can also remove all plugins and leave only the uart and blink for first tests)

then you can generate the Gateware with:
clear ; PYTHONPATH=. bin/rio-generator riocore/configs/LittleBee/config-uart.json

if all works, you will find a project file for gowin-ide here: Output/LittleBee/Gateware/rio.gprj







 

Pretty sure something like that can be done with LinuxCNC, as almost all motions are unique and repeat all the time, so each station has a single motion to do.
Probably most can be done with separate stepgens or siggens and some hal fiddling to ensure the tools are in place before moving the main part holder.
Add a VCP for editing values tools have to move and....

This is from back when i started using LinuxCNC and thinking what can be controlled by it, so just stuff in my head as i never had a chance to try and build such a machine.

Ah, I see.
I'm afraid not. LinuxCNC is not multi-channel capable so it cannot synchronize axes moving along different tool paths at the same time.

[edit]
The only way this could work would be to use a different installation of LinuxCNC for each station and synchronize the program execution using digital IO
