Remora - ethernet NVEM cnc board

pip is for python pip3 is for python3.

@aol you need Python and Python3 installed than if not already installed use Python to install pip or pip3 accordingly than
install tftpy with "pip install tftpy" or "pip3 install tftpy"

"sudo apt install python3-pip -y"

check with "pip3 --version"

It is easier to help if you post whole terminal output after running command.
don't forget to run: "sudo apt update" between installation of components and it has no errors that could cause you more headache

I believe that pip3 was working for me to install tftpy but I found issiues with some linuxcnc deb releases although rpi should not have problem with tftpy installation.

All issiues have been mentioned earlier as well and try not to repeat already resolved problems. I wish forum to have timeline progress if in developement but we all been in here returning to 1st poage not once not twice

Still it is great pcs of work thanks @Scotta again and everyone involved.

hi raff110,
thanks for your help!
i thought i have install newest version...

here is the complete terminal window.

cnc@raspberrypi:~$ pip install tftpy
error: externally-managed-environment

× This environment is externally managed

Hello everybody
I've been following this topic for a while and I think remora is really cool.
But is there a video explaining how to put the firmware on a nvem RT1052 card because I only find videos for STMs.
Thank you very much for all the information

Hi everyone
-For my EC500 V5
I was able to flash my board and upload the config. I think my hal, config and component are ok in linuxcnc. I can come out of estop and the serial data look all right. My motors don't move and no error is reported in linux but the dro is changing. I have DC servo and I think my drive need the pulse to be positive low to high.
1- Does the EC500 output the pulse correctly for my drives?
2- I took the nvmpg.c component in the nvem directory, is this ok ? Not sure I have the right one
-I also own a EC500 V3 STM32F407
3-Do I have to compile the code myself to put remora on it? I don see any .bin file in the EC500 STM32 repo
4- I think no new feature gonna be added to this on but . I know the RT1052 is faster but is there other differences I need to be aware

Thank you Scott for your great work, this project is awesome

Drive documentation
 

1. you may need to change the modifier in your config file to something like PULL UP or PULL DOWN
2. , just install both github.com/scottalford75/Remora-NVEM/tre.../LinuxCNC/Components
3. , no its provided as a hex file github.com/scottalford75/Remora-EC500/tree/main/Firmware
4. the 1052 has encoder support aswell as dma stepgen


@aol, i think thats something with the new debian install. other users have that issue, unrelated to linuxcnc im fairly sure . you might have to google search to find it.


@raf, it would be more than helpful to compile all the knowedge you have required into some official documentation. remora-docs.readthedocs.io/en/latest/ , it would be very helpful. im sure we would all appreciate it.

re :-
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install

If you are using a newer version of Debian you will get this error.
I am Using Bookworm (Debian). Here is the sequence that worked for me.

sudo apt install python3-pip -y
pip3 install tftpy --break-system-packages
python3 upload_config.py ec500-rt1052-DMA_full.txt

the dramatic sounding "--break-system-packages" doesn't seem to have affected anything yet.

Thanks
Alex

I have already thought of doing it
I would but not sure how to use git to edit. Would be probably better starting new from scratch and provide it for manual if accepted by scotta.

I have not finished configuring my machine to fully working linuxcnc.

Drive documentation
 

For your SMT based EC500. The firmware is here github.com/scottalford75/Remora-EC500/tree/main/Firmware

How have you wired your drive to the EC500? The EC500 has differential outputs, where your drive has single ended so you will need to pick up a ground and just use one side of the differential pair. You should be able to get it to work. Start with the default config so you don't have issues with step length.

Hello everyone.
No one to give me a little helping hand??
