So, ich habe mir mal einen normalen Drehencoder besorgt und den an die 7i76 angeschlossen. Dort wechselt "Count" nur zwischen 0 und -1, "B" blinkt wenn ich den Encoder drehe und "A" leuchtet konstant in der HAL Show. "Velocity" und "Raw Counts" tut sich gar nicht. Stecke ich nun um auf die 7i85 (Ausgang 02), dann funktioniert alles wie es soll, "RAW Counts" und "Counts" werden gezählt, ein Wechsel zwischen "A" und "B", also alles so wie es sein soll. Keine Ahnung, warum das so ist. Jetzt warte ich noch auf 2 GT2 Riemenräder und den Zahnriemen, dann kann ich das Ganze mit Motor testen, ob es dann mit dem Gewinde funktioniert.

So, I got myself a normal rotary encoder and connected it to the 7i76. There “Count” only changes between 0 and -1, “B” flashes when I turn the encoder and “A” lights up constantly in the HAL show. “Velocity” and ‘Raw Counts’ do not change at all. If I now switch to the 7i85 (output 02), everything works as it should, “RAW Counts” and “Counts” are counted, a change between “A” and “B”, so everything is as it should be. No idea why this is the case. Now I'm waiting for 2 GT2 pulleys and the timing belt, then I can test the whole thing with the motor to see if it works with the thread.

Mint 22 with LinuxCNC 2.10, sim works.

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

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.
