Remora - ethernet NVEM / EC300 / EC500 cnc board

Today I've tried again and board seems to be empty, there is no eth connection. 3 diods are on. I cannot flash any firmware with stlink2.
Have you got any ideas how to fix it?

I'm not sure is my stlink is still good. I've tried to update firmware on stlink with their software and it shows firmware corrupted error 

Update :

I believe my stlink stopped working fine. I've used nanoDaplink and there was still no answer from the nvem. Finally I've pushed (and keep it pressed) reset button on nvem, then start flashing with pyocd. When I started pyocd I've released reset button and whole process went fine from there. It was flashed with remora 3.1.3. Later I've connected ethernet and tried to ping. One of the leds on nvem went off and my ping was succefull. Then I've used this config :

github.com/scottalford75/Remora-RT1052-c...NC%2Fnvem-rt1052.txt

And it was all good. Previously I've used by mistake basic and full config from here :

github.com/scottalford75/Remora-NVEM/blo...vem-basic-config.txt

Which I believe was not for RT1052 version of nvem board. DON'T USE THIS CONFIG. 


Quick install eth component and everything works perfectly. I can move 3 connected axis with this linuxcnc config :

github.com/scottalford75/Remora-RT1052-c...Fremora-rt1052-basic

But this Linux cnc config is only for 3 axes. Do I have to manually set my 4th axis? 

Next step will be adding limit switches, one for each axis (except 4th). Maybe this evening I will find some time. 

 

Hi mate,
You have to hold Reset button before starting pyocd command, when pressed start pyocd flash command and quickly release board reset button.
That works 100% for my nvem.
If you dont have reset button on your board try manual reset by looking on your board pinouts.

Yes, you will need to configure both the INI and HAL files so LinuxCNC can use the additional axis. The NVEM config file you have used as all 6 axes configured. For the LinuxCNC configuration, I'd suggest posting questions in:

forum.linuxcnc.org/49-basic-configuration
forum.linuxcnc.org/10-advanced-configuration

Ok, I was able to set emergency button (ext), probe and limits. But when I tried to go from x0 to X50, it stops at 49.995, when I try to go back it stops at - 0.005. My j0pos-cmd is different than j0pos-fb by 0.005 all the time. I've never had that kind of issues with simple lpt port board. I'm using default basic remora config as a base for my setup. I've asked in basic configuration category but there is no answer for few days.

My current guess is about FERROR and ferror_min. 
But I'm not sure why my setup behieve like this

You'd prolly have better luck sharing your config + hardware/step setups. Bet some here could fine tune this for you being able to see clearer. 

No, not ferror. PID rather. Hack it with deadband = 0.001 (for instance). Bit of a band-aid though...
