Remora - ethernet NVEM / EC300 / EC500 cnc board

No it's still the same. The first clip is in CSS mode. The signal is gradually tapering up and down when moving in 10mm moves. You can hear the spindle nearly stopping as it's tapering up or down, only when it levels out again it goes to the required speed.

The second clip is out of CSS mode and manually pressing the Jog buttons. The signal has sharp edges as it's going straight to the required speed instead of tapering up or down .

I still can't figure out why this is happening. My VFD requires a 0-10v input. I'll hook up an oscilloscope to the speed input on the VFD and see what's happening.

Hello, everybody!

About 1.5 years ago I tried going the Remora route on my NVEM V2 with the STM32F207 and a Raspberry Pi 4. After a steep learning curve I finally managed to get the motors to turn, but experienced an issue where the motors would stutter, or skip steps, for some reason. Despite some kind peoples best effort to help, I was never successful in solving the issue and my PrintNC has been out of order since then.

I finally gathered some energy and wanted to give this another go, so I bought a mini-PC, a Lenovo M93p, mainly because I feel more comfortable using a real PC rather than a RasPi, and because it feels like there is more support for it.
Anyway, I followed all the same steps as the last time to get Remora up and running, but unfortunately the result is the same, the motors turn, but stutters.

1.5 years is a long time in the world of open source firmware development, so first of all I would like to ask if the Remora-NVEM repo is still the latest one for the NVEM V2? Or has the old NVEM V2 been integrated in another repo and has seen some updates since?

My next question would be, if it turns out that I simply can't get the NVEM to work properly, what is the board to buy nowadays? Is it the EC300?

Regards,
Christian

I have been using EC300 with Remora for the last four months, and it has been great. Once I got it up and running, I didn't have any problems. You can now get an EC300 with Remora firmware on eBay.

I noticed when looking at encoderS0.position I'm getting no valves. Also no valves when looking at spindle.0.revs in halshow. Could this be causing the issue ? EncoderS0.phase-Z is getting the signal from one of the remora input pins(my encoder index) which both are blinking in halshow when triggered. Should I be seeing the spindle.0.revs displaying a valve in halshow?

normally yes, it will increase, and then during threading i think, there is a reset index command which turns it to 0 i think. during css operation im not sure.

did you end up getting the abz encoder? did you do the spindle.speed-in stuff? monitor that while your doing the css and see if it takes a dive while the speed is changing. the remora.sp0 signal looks exactly as i would expect though, with the speed tapering up or down as the diameter changes.

Yes iv A and B hooked up to the PV which is working, counting fwd and back. Iv another encoder that came with the machine stock (emco encoder) that I'm using for the Z as it's 24v and hooked straight to an input pin. Yes iv the spindle speed in , in my Hal file same as yours.
