I am trying to get linux CNC setup to start a linear delta bot.
I have been searching, I think I have found some kinemetrics for it but I cant find anything to tell me how to setup linux cnc.

I am planning to run three steppers with stepper drives like geckos. A PC and the the PC LPT port.

I have done xyz setups like used in mills before but I am new to this kind of a setup.
If someone could point me to an example or some detailed instructions that would be great.
If you have a proven kinemetrics setup files they would be greatly appreciated also.

Thanks guys
Andy

You want these files here:
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...83b208ddc08d873db180

I have no idea where the files are now. They seem to have just evaporated from the LinuxCNC project.

lineardeltakins have always been in joints_axesNN branches as far as i know:
latest is joints_axes12

git.linuxcnc.org/gitweb?p=linuxcnc.git;a.../heads/joints_axes12

example sim configs are ldelta.ini, ldelta_demo.ini

git.linuxcnc.org/gitweb?p=linuxcnc.git;a.../heads/joints_axes12

Ah, that explains it.
I have never figured out how to tell which branch I am looking at in Gitweb.
Or how to tell which branch a commit was pushed to.

you can go to:
git.linuxcnc.org/gitweb?p=linuxcnc.git;a=summary
and then scroll down to the bottom where 'heads' are listed in order of activity

Yes, but what I mean is that once you have chosen a branch and are looking at a commit or in the tree, you can not see which branch you are in.
For example, this commit page
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...83b208ddc08d873db180
I don't know how to tell which branch that commit was applied to.

there is something odd about the commit you reference (a04ddb857feaaf3b) because the usual
method of finding containing branches:
git branch --contains a04ddb857feaaf3b
returns nothing.

The git --contains command works for the parent commit:
git branch --contains ab4fa67b1219
and one can checkout a04ddb857 (detached head) so the commit does still exist
$ git co a04ddb857
HEAD is now at a04ddb8... Linear delta kinematics
I wonder how you got the page link?

An old email from Charles Steinkuhler about lineardeltakins.

But even for a less odd commit, finding the branch that the commit was applied to is rather difficult in the web interface. (Which is all I have access to at work in my breaks)

Some of my problem was finding the files which is now taken care of, thank you.
But I have found some files in the past and was unable to determine what to do with the files, some help with this would be greatly appreciated.

First I see an .INI file, where does this need to be placed?
Second I see a .c and a .h file which I would think means compiling, if so is there some tutorial that tells me how to do this?
After this do I need to run setup again or am I just making adjustments for my system in the ini file or something.

I apologize for asking but in my earlier searches I have been unable to find answers to these questions, links pointing me in the right direction would be helpful also.

Thank you
