Acorn not controlling DMM Servo (Added video to my post)

I hope it works for you, it’s been a pain in the butt for me. Look forward to hearing how it goes.

In the DMMDRV software, did you set the Gear Num and Line Num both to 2000 and then go into the Wizard and set the steps per motor rev to 8000?

What you gain with higher step rate is faster rapids, which you may or may not need.
But very curious to know why you can't get 400khz out of the drive.

Yes, I tried Keith’s settings and DMM also tried their settings.

Marty thanks for the video, I made some changes in the configuration, of which annex photo, now the X, Y axes rotate in the same direction, do not make turn inversion, the Z axis moves very slow and does not make turn inversion

Marty gracias por el vídeo, hice algunos cambios en la configuración, del que anexo foto, ahora los ejes X,Y giran en la misma dirección, no hacen inversión de giro, el eje Z se mueve muy lento y no hace inversión de giro

I don’t think you’re supposed to have the step boxes checked in the advanced settings.

But it has been the only way to make the engines move.
I made all possible settings, also click on the address box and it also worked. So I am believing that there is something unconfigured about the Program and I don't know how to repair it.

Pero ha sido la única manera de hacer mover los motores.
hice todas las configuraciones posibles, tambien pulse la casilla de direccion y tambien funcionó . por lo que estoy creyendo que hay algo desconfigurado del Programa y no se como repararlo.

I just bench tested my new DYN-4 drive/motor, with new acorn Rev 4 and everything seems to working well.

https://youtu.be/aUbWI4FpHrA

IN DYN4 software:
I started by:
Confirmed servo turned in the DMMsoftware then changed to pulse/Dir/position ect per keiths Cheat sheet
- used CNCkeiths suggestion of 2048 Gear Number and Line number in DYN4 software (DMMDRV)
- I did not invert the enable in the DMMDYN4 software. (this seems to be a new feature in the software)
- saved everything, and read drive to confirm it saved

In acorn wizard
- I clicked on the radio button for DYN2/DYN4 and NO the estopOK
- Steps /REvolution set to 8192 (as keith suggested)
- I Unchecked the Enable in Advance Axis Configuration.
- set to 400Khz
- I did not change Parameter #991
- I know that every time I go into acorn wizard I'm going to have to uncheck the Enable in advance axis configuration before saving other settings.

note:
* these were my initial settings that worked so I left them alone. I don't know if changing parameter 991 or if inverting DYN4 enable in the DMM software instead will work any differently.
* I'm running everything on 240V
* I'm not using DMM's DYN4 cable but rather two 4 wire shielded cables and a DB25 breakout board.

Oswaldo, are you using the DYN4 pigtail cable? Let me know if you don't get it working. I was considering showing the connections/ bench testing on my youtube channel (in Spanish).
