Remora - ethernet NVEM / EC300 / EC500 cnc board

lol not offended, you move to fast, i was trying to stay one step ahead. but no you cant just load it as is, but its a very similar config as to what you want in the end. make a copy of your config folder, and replace a bunch of stuff. Specifically the [DISPLAY] section of the config, then there might be some probe related macro files and qtdragon related files. the remora-flexi.hal , dont touch i think. but there are some qtdragon hal files in there

Figured it out with the help of Hakan! Filled me in on what I was not getting. Working now, or at least far more complete than what I have ever had before.

Thank you!

@caskeslob. When I'm in CSS mode and moving the X axis . In halscope the Remora.sp signal looks like it's tapering , is it supposed to this? You can hear the spindle in the background slowing down with every adjustment . I'm moving in 10mm jogs .

Not in CSS mode

im not an expert but i think thats exactly what its supposed to look like (rpm changing as diameter changes). assuming those portions that are the straight lines are in between jog moves. I didnt see (or hear) any weird spindle speed drop outs like before thought. i am assuming you figured out the issue?

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?
