Remora - Rpi Software Stepping Using External Microcontroller via SPI

I dont know what would cause it to not work on the RPI4 vs the RPI3,

A couple things you can check though

- Does it work with AXIS on rpi4?

- Did you install the same component version as you did on RPI3?
If you are using the nucleo version, use the comp in that repo. The nucleo version uses a different linuxcnc component than main remora,

Hi Cakeslob,
Yes I have used your static config.
Same remora.c from your repository.

Hmm ok, as long as its this comp for nucleo boards, what ever repo you get the firmware, use that component
github.com/cakeslob/Remora/tree/nucleo_s...NC/Components/Remora

Hmm on second thought, it could be this,
In your hal file in the loadrt remora try adding this

I have the nucleo 446 running at a higher base thread in the firmware, so the linuxcnc side component needs to match.


I dont have an RPI3, Ive been using RPI4. I can recommend you try this image if it still doesnt work
github.com/Expatria-Technologies/remora-flexi-hal/releases

Viren, I would like to use a trimmed down version of your lathe configuration as one of the provided sample config. I hope this is ok.

Also, can you post a file with threading?
I am working on my tiny remora lathe, but I dont know how to set it up or how to use a cnc lathe. I was hoping I can copy most of your config file and also use it as a sample hal file for the remora project.
I hope this is alright with you.

I will be more than happy, to share something I know how.
meanwhile, I added your suggestion to .hal file. did not work.
  

Ok, thanks Viren.


Hmm that is odd for sure. I am only using RPI4. I dont know exactly the difference between RPI3 vs RPI4 in regards to SPI

What board are you using with your setup? I dont think it should matter, but just wondering

Also, how long is your cables?
I had to use shorter cables than I normal (3d printer boards I was using around 100-130mm) with my nucleo setup, I had to use less than 100mm cable length.

ok, just to have our bases covered
- leave the base_freq entry in hal regardless, we need that for the nucleo repo
- test with axis gui, (shouldnt be any different but lets make sure)
- try the flexi-hal RPI4 image, that one should positively work software side.
- copy the comp from your RPI 3 setup. I dont think Ive made any changes since you first installed, but just double check
