Hi
after installing the official LinuxCNC ISO for Raspberry Pi 5
I realized that the screen resolution is not good,
it is not manageable and there is no audio,

it will surely be fixed.

so I tried installing LinuxCNC + EtherCAT on native Raspberry OS
I installed kernel 6.6.45-rt39-v8-16k+ with inspiration from  here
for EtherCAT drivers I entered the keys for the repositories from here
and followed Rod's guide here here

Everything works

 

latency, maybe a little high

 

I was wondering if it depends on the kernel and if it is possible to modify it in some way
many Thanks

Hi PCW
Please make sure for me this wiring diagram me correct or not ?

Thank you

Hallo, ich muß das später noch mal nachtragen.

Hat nicht geklappt..

bis später

Ok tommylight und danke….
Torch on und Ark ok sowie 0-10 V für den Strom habe ich im Standart-Anschluss Zwei hätte ich frei gehabt der Anschluss ist aber nicht geschirmte !
Nun gut wenn das Probleme macht das bekommt das Gerät ein weiteren Plug mit Cat-Kabel.

thanks a lot

Yes. You are. Confirmed. 1000% spot on and a great visionary (imho).

If you don't mind/allow, let me know when you believe to have a semi-final stable solution of the Generator & Gui and I'll fork over. I'll bring in RIO for a "Gowin-Only Maintained Solution" and clean up the code of other toolchains, and everything else irrelevant to gowin. We can swap updates/features and ideas along. I'll point over to you for sources...  

ps. great way to publish that 5ax board sources and offloading from you any potential support/requests relating to that board/solution. 

You need to install the  linuxcnc image from the downloads page then follow the first post here

Looking at my notes on my Melfa robot config using absolute encoders it seems that the value in [Joint_n] SCALE is
360/gearbox_ratio
So for my 80:1 geared J0 I have SCALE = -4.5
for my 120:1 J1 I have SCALE = -3

And so on.

I'm not sure how I came up with that idea but it certainly works for me.

thanks guys, you show me again that i'm on the right track

One of the reasons for RIO was the poor availability of mesa boards.

i will concentrate again on the ICE40 and epc5 in connection with yosys/nestpnr. There I have no stress with licences or availability.

with Kicat it works better and better (before i was very limited with eagle-cad), so i will probably build another board like the Tangoboard, but this time with ICE40 and with W5500 .

I might also pursue an old approach for a modular board,
I had already done some tests:






 

thanks a lot
What steps should I follow to configure ethercat?

cnc@raspberrypi:~/Desktop$ ethercat slave
bash: ethercat: command not found
cnc@raspberrypi:~/Desktop$ sudo geany /etc/ethercat.conf
cnc@raspberrypi:~/Desktop$ sudo systemctl enable ethercat.service
Failed to enable unit: Unit file ethercat.service does not exist.
cnc@raspberrypi:~/Desktop$ sudo systemctl start ethercat.service
Failed to start ethercat.service: Unit ethercat.service not found.
cnc@raspberrypi:~/Desktop$ sudo systemctl status ethercat.service
Unit ethercat.service could not be found.
cnc@raspberrypi:~/Desktop$ sudo chmod 666 /dev/EtherCAT0

Don't. Don't do it man lol You've been warned. We'll figure out a way to get this board made avail somehow, no choice (in my case anyway).

Cant do this anymore bye all wrote:

Magic words!! I just did too, gotta call it quit bcuz I honestly can't make this medieval decade old crap working half-reliably whatever I try. Spent most of today learning this analconda python env, the whole things randomly puts up missing headers although all deps are in, ISE freezes, throws million warnings for no valid reasons, let alone unable to flash a bin over using openfpga among several others I've tried. Just nothing at all works - utter thrash all around in a few words. 20+hrs I'll never have back lool Honestly not recommending anyone to jump in the same bunny hole as I did, annihilates the awesomeness and rep of RIO entirely.

Nuff ghetto. Back to Gowin's EDA. Epic simplicity, less than gig dwload high-performance eda, 15mhz bin flasher/debugger, flawless under linux, ultimate 2-clicks-max joy at a reasonable price. STRONGLY ADVISED. 

Hello Todd,
I understand that you make example of "incremental encoder" with quadrature.
My encoder is 17 bit absolute multi-turn type, so the counts for one turn is huge value 131072.
I calculate: 131072*80/360 = 29127.111111. Is it still correct to apply ?.

I put ENCODER_SCALE = 29127.111111 to INI file, but nothing happen.
I understand need to revise HAL file to use ENCODER_SCALE, but it seem encoder component is only suitable to incremental encoder type.
linuxcnc.org/docs/devel/html/man/man9/encoder.9.html

Please advise Thank you.
