Remora - ethernet NVEM / EC300 / EC500 cnc board

Thank You for the response!
I had the machine running with a parallel BOB. I have microsteps, current, acceleration configured already, did not change those. Steppers had a "healthy whining" sound. Only the EC300 is new.

The "faster" DMAstepgen doesn’t generate any movement for me. As far as I know, you can only set timings in DMA configuration.
My timings are exactly as Yours.

I have my config here for ec500 with nvmpg: github.com/zelo/linuxcnc-remora-ec500-rt1052-cfg  
Thank you, Zelo, for your response.

Unsurprisingly, your EC500 config file didn't work with my NVEM V5 board. So what I tried next was to git clone the repo named Remora-NVEM instead of the one I used previously named Remora-RT1052-cpp. However, when I uploaded the nvem-full-config.txt to the board, it messed things up, and now nothing works. It doesn't even accept any other config uploads anymore, and I'm stuck. I think I would have to reflash it and start all over again.

Anyway, back to my original problem: The outputs of the NVEM V5 board are all unresponsive, no matter what config I use. If anyone has a working setup for the output pins with the NVEM V5 board, please share it. Thank you so much.

By the way, just for a sanity check — when the output pins are high, should they be outputting 12V? What I'm doing is measuring all the OUTPUT(+) pins with COM(-), but I get a 0V reading. I assumed it’s not working, so any guidance would be much appreciated!

I’ve attached a picture that shows the difference between the responsive and unresponsive pins for reference.

Okay. I'm officially lost. I can't get the stepper motors to work normally. Everything else works or would work with a few configuration changes if the movement was resolved. With the ec300-rt1052.txt configuration, the steppers have the grinding sound you can hear in the linked video.

BSOD, I've had a similar issue before, and in my case, it was caused by the wiring of the stepper drivers. I would suggest trying the following:

1. Connect all the V+ pins of the stepper drivers to the Common pin of the EC500.
2. Then, connect each signal (Step & Dir) from the EC500 to the negative pins of the drivers.

If your current setup is already configured like that, try reversing the connections, i.e., connect the V+ pins to the negative pin of the EC500, and the signal pins (Step & Dir) to the Common pin.

This adjustment worked for me in the past, so hopefully, it will resolve the issue for you. Let me know if this helps!

IT'S  A L I V E !!!
Thank you! I had everything at least triple checked. I've never would have thought to reverse polarity on the signals. Actually, common sense tells me to watch polarity very carefully, to contain the magic smoke where it belongs.

 

MrDe I don't have NVEM V5 but i guess this config here is for it: github.com/scottalford75/Remora-RT1052-c...xCNC/nvem-rt1052.txt
Just make sure you have RT1052 version.

zelo, you speeds in your config arent that crazy. you should be abkle to go faster. if you are only seeing the issue with jogging, try doing a test, by lowering the accel and raising the velocity.
