Thank you very much! That would helps me a lot! When you have time it would be very nice when you can write the hal and ini file. I only need 3 Axes (X,Y,Z) 1 Input for home and 2 outputs for mist and flood and 1 pwm for spindle speed. I will also look at the example of the HAL file, so i can learn a little bit and try it out!

Sorry TOLP to disturb again. Ive Tried installing litexcnc and get this error:
Collecting litexcnc
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: pypi.org/simple/litexcnc/

Is there an solution?
Thanks

This is because there is no 'official' release to pypi.org yet. To install the package you should use:

pip install --extra-index-url https://test.pypi.org/simple/ litexcnc[cli]

I think in my previous post I forgot the /simple/ part in the command. Will verify and change it there as well. Without this addition, Thanks for trying!

For your use case, you can use the pre-made configurations on this documentation page. You should download the documentation for the version of the board you have. I would recommend the use of the 'named' version of the configuration over the 'indexed' one. Why? With the 'named' version all pin numbers will show up in the HAL with their name, i.e. J1:1 (which is thus pin 1 on connector 1).

For your HAL, I think the code below is a nice starting point:

loadrt [KINS]KINEMATICS
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS
loadrt litexcnc
loadrt litexcnc_eth config_file="[LITEXCNC]CONFIG_FILE"
loadrt pos2vel number=3

# Add the functions to the thread
addf [LITEXCNC](NAME).read servo-thread
addf motion-command-handler servo-thread
addf motion-controller servo-thread
addf pos2vel.convert servo-thread
addf [LITEXCNC](NAME).write servo-thread

The above HAL-file needs a speciel section in the INI-file:

[...]

[LITEXCNC]
CONFIG_FILE=<path to your config file>
NAME=<name of the card from the config file>

A good tactic for getting this up and running is to use the standard step config to generate the structure and the basis for your HAL file. Then you replace the stepgen with the part above and change the required settings.

I´m Sorry but this link also not working. I have put now to the test.pypi.org to firefox and I searching for litexcnc - tadaa - there it is - don`t know why.
So I downloaded the Source Distribution
litexcnc-0.9.0a3.tar.gz

Strange, can you please share your input and output from your command line, i.e.:

$ pip install --extra-index-url https://test.pypi.org/simple/ litexcnc[cli]

There are also some other possibilities:

you need Python 3.8 or higher. So if you have 3.7 installed, pip cannot find this version;
if you have Python 3.8, your might use pip3 depending on your system. The standard pip might default to Python 2.x version.
last resort: update pip (pip install -U pip)

I will check whether I can draft a release which also supports Python 3.7, because it is the last version which is in the older Debian repos.

So I think thats my problem - i have Python 3.7 installed.I Will update pip. How can I Upload to python 3.8? also when i try the command without pip3 and only pip the say I have only Python 2.7 Installed..

Checking at this moment whether it installs on Python 3.7. If it works, I'll directly release a new version.

Seems like you have multiple python installations on your system. I just released alpha-4, which does support Python 3.7, so you should be able installing it with the first command.

If the python 3.7 installation is on path (which is assume to be, as pip3 is on path), the scripts like install_driver should work and you won;t have to bother with the Python version hell.
