Remora - ethernet NVEM / EC300 / EC500 cnc board

buenas necesito la ayuda de algun experto ,, yo soy un novato en esto pero quiero aprender,, a la hora de cargar los componentes me sale este error....

Hi Everyone,
recently I was trying to get started with EC500. I was able to flash the firmware and was able to ping the board on the 10.10.10.10 address. It worked nicely with a pico probe and pyocd.

However, I continuously get joint following errors on all my joints while jogging and while executing gcodes. I cannot get rid of them.

Also, the following error is very high, even at low speeds it is more than 1mm. I also tried to increase the P gain or to increase the spike filter in remora-eth.c component without success.
My computer has the following latency  values:
 

If I ping the board over a longer period of time, I get following values:
 

There are some outliers with high ping, but they are rare.

I already tried to reduce the jitter:
- Isolated two cores
- Moved kernel threads to the non isolated core
- Moved NIC interrupt to the isolated core

I can think there can be two source of problems now:
1. Latency jitter of the NIC
2. Latency jitter of the PC (Fujitsu Esprimo P556)

Can you give me some advice please how to debug this problem? How could I trace down which one is the issue?
Thank you for your help.

Hi, it's very unlikely that following errors are being caused by jitter. The control loop should compensate for that. Why do you have your [TRAJ] MAX_LINEAR_VELOCITY so much lower than you [JOINT_n] MAX_VELOCITY? 

The [TRAJ] MAX_LINEAR_VELOCITY should be higher than the joint max velocities otherwise the frequency command will be limited.
github.com/scottalford75/Remora-RT1052-c...emora-eth-3.0.c#L545

This means that the control loop would never be able to catch up the following error.

Also, it looks like you are not you loading the latest version of the component. loadrt remora-eth-3.0

Hi guysI have not seen that anyone mentioned LCD display that can be connected to NVEM boards via serial port (small white)There is not much info on AliExpress


Could this be easily implemented to be used directly with board? 
I do not own it myself but more info if this is touchscreen with jog or just preview for DRO.

I will just leave it here for initial data collection

Hi Scott,
thank you for the hint. I'm loading the right version, just renamed it to keep overview.

I increased the values as my new attached INI configuration. I increased the [TRAJ]MAX_LINEAR_VELOCITY to a large value.
The P gain that worked best is 1000 (similar to a mesa configuration). I set the FF1 gain to 0.95, which gives reasonable results.

Now, the error comes not immediately, but for after 3-4 seconds, most often at the end of a jog move.
 

In this example, I'm jogging alternatively in positive and in negative directions. The following error has some very large sudden spikes.I made the spike filter parametric and experimented with different values, but they do not make any difference (n=2,4,8, m=500).

Hi everyone

How have you resolved your ENA output on NVEMv5 board in linuxcnc HAL file and in config.txt if different?
I have tried OUT1 on remora.output.00 and @cakeslob help with no success.
Could this work on Aaxis outputs pins.

To clairify what Raf is talking about,
We are trying to set the enable pin for the stepper drivers, to control them from linuxcnc like normal. We are wondering how everyone else is wiring up their enable pin. Im not finding any examples of it in the configs, so it made me curious. Wondering what pin was used and how you wired it, it would be appreciated.

This is the error that appears after compiling remora-eth.c

Hey Ray, first, I think you should be installing this one, if you are using the RT1052 version
github.com/cakeslob/Remora-RT1052-cpp/tr...omponents/Remora-eth

second, I think your linux version is probably to old. weezy is old, and thats most likely why it wont compile

Thank you very much I thought I was not going to get help, the version I use is nvem v2 which has the SMT 32 microcontroller, I have a PC with an x86 processor, the latest version that supports this architecture I understand that it is whezly although I have updated to Linuxcnc 2.8.4 ...is there a solution to make it work with whezly?

ok good, so you are using the correct component for your board for the STM32

What to make it work? I am not sure. I am not 100% sure its because you are using wheezy, but I think its very likely. The kernel looks like 3.4? Which is very old, and wheezy was released over 10 years ago. I didnt know of a solution

is the RT kernel RTAI? that could be why maybe
