ColorCNC Colorlight 5A-75E/5A-75B as FPGA controller board

I really like this project.
Today the second 5A-75B-V8.0 will arrive. Can´t wait to flash it with LiteX.

And when I get the workflow for the modules finally, things will become even more exciting

@TOLP2 can you explain how to deal with stepgen constraints and how to set them properly? Imagine that one is implementing a machine with servo drives configured to 1000 steps/mm and maximum speed 1m/sec (60m/min) (this yields 1 MHz step clock). Let servo period will be 500 usec, jitter is 10 usec (10/500=2%) and expected joint following error 20 um at a maximum speed (possible position error caused by jitter at a maximum speed: 10us*1m/sec=+-10 um). Are these values achievable? How to set up pick up value properly?

Maybe this answer which helped me, will help you....

forum.linuxcnc.org/27-driver-boards/4442...ard?start=490#263931

As mentioned in the documentation, the max step frequency will be 400kHz

There is already 54 pages...
Can anybody give brief info, is ColorCNC works, is ready for use in real machine, and how to install it?
Thanks in advance.

Here is my way....

Install Linux from official ISO
DEBIAN 10 - LINUXCNC 2.8.4 - ISO

Install packages:

sudo apt install python3-pip
sudo apt install git

pip3 install pydantic==1.10.5
pip3 install packaging==21.3
pip3 install ninja==1.11.1
pip3 install chardet==5.1.0
pip3 install meson==0.64.1
pip3 install requests==2.28.2
pip3 install yapps==2.2.0
pip3 install importlib-metadata

pip3 install -i test.pypi.org/simple/ litexcnc[cli]==0.9.0a5
litexcnc install_litex --user
litexcnc install_toolchain --user


#edit or check .bashrc and .profile
# set PATH so it includes user's private bin and oss-cad-suite directories if it exists
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

# set PATH so it includes oss-cad-suite
if [ -d "/home/oj/oss-cad-suite/bin" ] ; then
PATH="/home/oj/oss-cad-suite/bin:$PATH"
fi

Install driver for LinuxCNC
litexcnc install_driver

this will compile the modules for linuxcnc. when you get the no permission error to copy the files to the linuxcnc folder you
will have to modify the file install_driver.py on line 19. found in ~/.local/lib/python3.7/site-packages/litexcnc/cli/
change 'halcompile.py --install' to 'halcompile.py --compile'

run 'litexcnc install_driver' again and it will compile the driver without copy them.

then copy the modules manually with sudo

open a terminal
cd .local/lib/python3.7/site-packages/litexcnc/driver/
sudo cp litexcnc.so /usr/lib/linuxcnc/modules
sudo cp litexcnc_eth.so /usr/lib/linuxcnc/modules
sudo cp pos2vel.so /usr/lib/linuxcnc/modules


create, or edit a JSON config file for your board. I used one of the examples and changed to my needs
litex-cnc.readthedocs.io/en/latest/examples/index.html

litexcnc build_firmware "<path-to-your-configuration.json>" --build

Is this project alive?  Any real world schematics/examples.!

The project is alive, please check this: github.com/q3k/chubby75/issues/107#issuecomment-1517377816
@TOLP2 is working on his prove of concept.

I have a question...

How to write bitstream to flash?

I have installed litex-cnc and all I need, I can compile bitstreams.
I have got Lattice HW-USBN-2A and installed Lattice Diamond Programmer, I can write bitstream to FPGA, but the W25Q32 flash chip is invisible.
This is not problem in development, but CNC driver which losts firmware at every power off is unusable...

I mentioned the same and was checking if I did something wrong. Apparently I'm not the only one
I'm using a "ESP-prog" to program my FPGA

Due I'm quite unexperienced with LinuxCNC I am looking for easy way to create an configuration to get started...
Let's say I am building a XYZ mill with 2 Y motors.

can't wait to play with it
