scara making curves

Hello i am pretty new with linux and aslo with linuxcnc, i know the basic things about programing, i can do that a scara can move into my control board, but i have a question, moving the joints it moves correctrly that the screen says, but when i try to move on world mode, on x it mad kind of well but made like a reallly big circule, but on y made a small circule that not move on the right axis, and i have to but on these order X Y Z C , i have to use the C axis to the rotatory becuase if i use the A it dont move and start to do more strange things.

can somebody help or have any idea about that issue i am using the last linuxcnc and the scarakins, now im trying to do an personal scara kinematics but i have some library errors.

I doubt you have a issue with the kins probably an issue with the setup or measurements. Scaras are sensitive to incorrect arm length measurements.


Read the docs for scara kins and make sure your ini is setup correctly. If that doesn't work post them here
