When I tried the Qt Touchy it would not start and gave this error as well as some strange noise out the speakers.
 

Running Debian 12

listing said 4A max and said it was an upgraded version i have not picked up any power supplies yet. usually China ratings are exaggerated so i never go to the max. i think the motors are rated at 3 A. I will keep that in mind regardless. maybe i will get some sort of manual with them when they get here? I will have to wait and see. but if i smoke a $7 drive it won't hurt to bad

In a terminal, what does
xrandr
Return for available resolutions?

I have those drives, they are good, they have issues, and for sure will die at 42V!
Those use the TB67S109 chip (IIRC) that has the absolute max rating of 40V or 42V, and a working rating of 24V, i have them running at 27V without issues for years, but i would not go any further than 32V.
They have good microstepping, have some protections, and do not die like TB6600, also less sensitive to EMI than TB6600.
Also cheaper than TB6600.
Max current is 3.5A, should be plenty.

Fixed the 7i78 stepgens, download the deb again and reinstall.

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.
