Machine Parts Building

Hey Guys,

I'm currently new in Linuxcnc and the project I'm working at is 4-axis linear delta.
Started to understand the ini. and hal. files and the problem that i'm facing is that i cann't define the machine parts on linuxcnc so i can control it. 
if anyone know how to do this I will be grateful.

Not exactly sure what you are asking but there is a kinematic called 'lineardeltakins':
linuxcnc.org/docs/ja/html/man/man9/lineardeltakins.9.html

That would be 3axis I guess.

So do you need an additional C axis like a hand twist?

Hello,
Can you tell me the exact path to the file which is called 'lineardeltakins'?
I've found it on the LinuxCNC Github repo and there were 3 lineardeltakins files: lineardeltakins-common.h, lineardeltakins.c, and lineardeltakins.cc.
I'm not able to find any of these files on LinuxCNC on my device?
can you point out the exact path to those files?
Thank You.

If you have built linuxcnc from source then you should find it here:

your_linuxcnc_folder/src/emc/kinematics/lineardeltakins.c


[edit]
If you have installed through the package manager or the official ISO then it will be somewhere in your root directory.
I don't have such an installation but you could search for it in terminal:
sudo find / -name lineardeltakins.c

It's just been pointed out to me that if you don't have built linuxcnc on your machine then the .c files are not present since you only need to compiled files. So lineardeltakins.c would not be present on a deb install.
