That's a warning, not an error. You can usually fix it by copying the libusb.dll (libusb dynamic link library) to the path of your Python installation.

Note: If you downloaded Python from the Windows Store, you should copy libusb.dll to the C:/windows/system32 directory.

C'est un avertissement, pas une erreur. Vous pouvez généralement le corriger
en copiant le fichier libusb.dll (bibliothèque de liens dynamiques libusb) dans le chemin de votre installation Python.

Remarque : si vous avez téléchargé Python depuis le Windows Store, vous devez copier libusb.dll dans le répertoire C:/windows/system32.

in the directories VS2013,VS2015,VS2017,VS2022 there is a libusb-1.0.dll in each folder

Hi, there's some additional config parameters that can be used to configure the DMA stepgen. "Step Length", "Step Space", "Dir Hold" and "Dir Setup".

From the HBS86H data sheet:

PUL: pulse width should be longer than 10μs
DIR: signal should be ahead of PUL signal by 5μs at least

Therefore I'd suggest these settings in your config.txt as a starting point.

"Step Length": 10
"Dir Setup": 5

The normal stepgen runs at 40Khz so most drivers are happy with the step form being generated.

Scott, thank you very much for pointing me in the right direction. I made changes to the configuration file "ec500-rt1052-DMA.txt" (JSON) according to your guidelines. I modified the parameters: "Step Length": 10, "Step Space": 5, but for now, I’m applying it only to one axis, X - JOINT_0, for testing purposes. I’m glad you helped me. Of course, in the *.ini file, I adjusted the SCALE parameter to match the settings from the HBS86H (microsteps) and to ensure movements are adapted to the lead of the ball screw. For now, everything is set up on the floor at home. In the future, I plan to install the Remora system on my new CNC machine, which I’ve been building for a long time (mainly because it’s very heavy, as it’s supposed to be, and requires a lot of work). I want it to be faster in its movements than my current one, which operates on a parallel port. If I have any questions, I’ll definitely ask you or others on the forum. It’s great that you’re all here and creating such amazing things. Take care for now.   Christopher - tu_koper.
