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

To check the hardware, I tried Inga's colorcnc project ( this ). Inputs, outputs and PWM work correctly. There are questions with stepgens, but they are related to hal file settings.

Is it possible to make 5 axis closed loop cnc with the 5A-75E/5A-75B boards ? 

Dear svb
To run LiteX-CNC do I have to install LiteX first?
Can a tutorial on detailed commands be issued?

Yes, of course

What tutorial you mean?
For LiteX? On github LiteX page.
For Litex-CNC? On github Litex-CNC page.

It will be available in the future if there are opportunities and time for TOLP2 to make this functionality

Hi, I'm having troubles to create the firmware, can you help ?

Hi.
Small instruction

Pre-requisite.
Check for LiteX environment installed. (Read LiteX wiki how to install LiteX)
Check for OSS-CAD-SUITE installed

1. Clone LiteX-CNC GIT repo, branch envoders!!!
git clone github.com/Peter-van-Tol/LiteX-CNC.git -b envoders LiteX-CNC
2. cd LiteX-CNC
3. python3 -m firmware examples/Your_json_Examples.json
If all installed correct you do not have any errors and get your test config ok.
4. For example, you select examples/5a-75e.json
In LiteX-CNC after running command from "3." you now have forder named as you examples, i.e. 5a-75e.
cd 5a-75e
you will see 2 folders - software and gateware. We need cd to gateware
in this folder run Shell script,for my examples will be build_colorlight_5a_75e.sh
sh ./build_colorlight_5a_75e.sh
if all pre-req installed correctly after this script is finished you get build_colorlight_5a_75e.bit and build_colorlight_5a_75e.svf file in this folder
Flash any of this file with your preffered soft.
End

No No No No!!!!

buffer_depth MUST BE LESS or equal 256!!!

In old version Litex-CNC:
buffer_depth: int = Field(
1060,
help_text="The size of the buffer for the Etherbone protocol. Should be "
"large enough to fit all data for communication with LinuxCNC. TODO: check "
"whether this size can be automatically determined."
)

To kwarup:
probably you use the main branch, use branches envoders
