Hi, i am testing the linuxcnc hal file and remora rp2040+w5500 and have a question how add outputs in the config file for enable spindle and enable coolant?. Thanks.

probably something like this

Hi
Please help me, I'm stuck.
I want to install Remora on W5500-EVB-PICO board, and I drag and drop the firmware and rp2040 answer at the ping on 10.10.10.10.
I do the rest of Linuxcnc setings and I receive the following error.


The file 'remora-nv.so' missing !
What I do wrong?
 

you need to install the component

github.com/scottalford75/Remora-NVEM/tre...Components/Remora-nv

remora-docs.readthedocs.io/en/latest/sof...mp-installation.html

I do
(sudo halcompile --install remora-eth.c) from here github.com/scottalford75/Remora/tree/mai...omponents/Remora-eth

(cp -a ~/linuxcnc/Remora/LinuxCNC/ConfigSamples/* ~/linuxcnc/configs) from here github.com/scottalford75/Remora/tree/mai...igSamples/remora-eth

dont use the eth, it is most likely outdated. your hal file is asking for remora-nv

Thanks! Now works, but over 100mm/min feed I receive a Joint 1 or 2 following error.

 
 

 

I use a old Dell E5500 for test and I want to be shure if latency is problem or my settings.

 

Thanks.
 

Did you load your pico pin configuration to the board using the upload_config.py ?

Try with this configuration, it should work.
github.com/Expatria-Technologies/linuxcn...ain/picobob-ethernet

I do all settings from Expartia github link and now support velocity until 7500mm/min but some time crash with 'joint X following error', error is random not every time in same 'place' of gcode and joint nr cud be any. (0,1,2). The crash dont appear every time, for example 3 time run all code without problem and 4 th time crash 2 times.
I suspect the latency problem.

From what i can gather, it is a latency issue, the screenshots you posted are terrible but that might be due to using base period for tests.
The main issue is you still get the warning about latency excursions on the servo period when starting LinuxCNC, and that has to be addressed first.

Hall scope on Joint0 fferror

When works ok. At Feed 4000 and G0 at 7500mm/min
 

 

 

When crash
 


At low speed Feed 400mm/min and G0 2000mm/min

 
 


I think is PID problem not latency.


Edit : With firmware form hire github.com/scottalford75/Remora-RP2040-W5500/tree/main/build is more stable now, but need PID adjust.
