ER-Spannzangen sind genormt in der DIN 6499.
Für eine ER-Spannzange braucht du ein ER-Spannzangenfutter und eine ER-Spannmutter.
ER-Spannzangen gibt es in verschiedenen Baurößen. ER40 Spannzangen gibt es typischerweise von 3 mm bis 26 mm.
Die Spannzangen in Übergröße würde ich versuchen zu vermeiden.
Die Spannzange wird in die Spannmutter eingeschnappt. Erst dann wird des Werkzeug in die Spannmutter gesteckt. Somit wird sichergestellt, dass beim Lösen die Spannzange wieder aus dem Spannfutter gezogen wird. Die Spannmutter und die Spannzange sind ungefähr bündig.

Das von dir verlinkte Spannzangenfutter ist OZ und somit nicht passend für ER Spannzangen

I just received a new PCB that I designed based on an AXIS sample project. It is a CIA402 test board.
According to the AXIS manual, it uses an STM32H745, which has 2 cores, both H7 and H4, and is expensive. I saw that all the configuration examples only use the H4 core, so I designed another STM32H723 as an alternative. It has a single core, the H7. It costs almost the same as the F407, which is much cheaper than the H745.

When I finish building the PCB, I hope to compile the files successfully with the knowledge I have gained from Hakan.

With the use of SOES github.com/OpenEtherCATsociety/SOES there is no difference for me as a programmer.
There is a tiny difference in how to reset the ESC chip, LAN9252 can be reset by writing over SPI, AX58100 need a pin to go low.
Ax58100 also has a pin for a led that indicates successful read of the eeprom. Pretty useless but has been nice diagnostics when starting up the board.
Other than that one can consider them identical.
I have seen someone state that the AX58100 is faster than the LAN9252. I can not see that, I haven't been in a situation where I can identify the ESC speed as a factor, on individual usec level.

If so, I will try LAN9252 on the next board.

The asix chips look nice on paper but then again if you pair it with a MCU, how much benefits are there, I don't know? I was just wondering if there are benefits from the programming side so that it would make sense to use that instead of the LAN9252. I have 0 experience with the asix chips so I would love to hear from people that have used both.

Although both maybe available on aliexpress, I would say the LAN9252 is far more obtainable than the asix chips. I typically try to scan something like octoparts for any "special" components I might use, at least if there is even a small chance I make something more than one. A quick look and just digikey and mouser stock these in the thousands. I lost my mind on the chip shortage so now days I try to find multiple sources for parts and if I'm lucky multiple alternatives.

I followed hackaday.io/project/181058-ethercat-serv...e/log/196311-ax58100 for years before the project switched to AX58100. There was a description between the two chips that I didn't quite understand until I found Kahan's project that switched to AX58100 and I followed suit.

@ pippin88  Yes, I started with this project to work with STMBL, but I was still a newbie with Ethercat, it was very confusing for me until I discovered Hakan's project that exposed kikad and explained it in detail on YouTube, with immediate response when I had problems via Github.

This is the AX58100 SPI to STM32F407VGT6 connection test board with Axis and IO expansion board.
I haven't made it into 1PCB yet due to the price constraints of PCB size exceeding 100X100mm.
I'm adding the DAC Op-amp circuit and waiting for the test. Encoder connection.

@Hakan Thanks for creating and sharing, I got the AX58100 working again. It's a very good project to share and learn. I've learned a lot from this project. It's a good starting point to learn how to create and use Ethereum by myself. There are some contents related to STM32 MCU, suitable for those who have no background. It works on VSCode, very beginner-friendly. I will update my board again.

hello
could you provide the hal connection for the stepper step/dir connection to the carousel component , i am using mesa 7i96s board

I will create non legacy mapping and update them here... It should be problem with my mapping shape .. I will load them to el6731 and double check  them with my stuff
 
regards

here is the non legacy stuff for single axis for DC sync ... as profibus for s600 and for s300 same, I tested them on my stuff and it should work for you too, I HOPE

if not dmesg me the output and I will check it asap

Hi everyone!

i'm quite new to linuxcnc and have some basic knowledge about linux, i don't want to compile a kernel and that stuff, installing specific packages are nit a problem...

at the moment i'm using a raspi 5 image from linuxcnc download page.
I have some resolution problems with my 7" touchpad, it loads the one and only available resolution 1920x...
i would like to have another resolution, my problem is that the "normal" things for raspi do not worl with debian image.

2 Questions:
- how do i do that with the linuxcnc debian image ?
- should i switch to the image provided here with raspios ?

i'm using the raspi together witth mesa ethernet card

thanks a lot

Lars
