I have a 3-axis rotary delta robot, my servos are running smoothly in trivkins, but when converting these settings to rotarydeltakins, I get the error "kinematicsInverse gave non-finite joint location on joint 0".
The .hal and .ini files are attached.

did you try setting the offsets in a Postgui file so the interpreter gets set up first
setp rotarydeltakins.platformradius 40.0
setp rotarydeltakins.thighlength 384.0
setp rotarydeltakins.shinlength 1091.0
setp rotarydeltakins.footradius 60.0
setp rotarydeltakins.platformradius 40.0
setp rotarydeltakins.thighlength 384.0
setp rotarydeltakins.shinlength 1091.0
setp rotarydeltakins.footradius 60.0

Thanks, it worked. So my servo motors should not move more than + - 55 degrees How can I adjust it?

there is a MAX
MIN
Limit in the INI for the Joints
the rest is up to the Postprocessor
You can try out Autodesk FeatherCam this makes pritty impressiv gcode on Rotarys

I cannot adjust how long the motors can move with the max min in INI, I just set the boundaries as the coordinate.
My motors can damage themselves if they move more than + -55 degrees. how can i set this up?
If it can be done from the INI file, I do not know which feature is affecting under which title.
Thans for helping

Assuming that you are using LinuxCNC v2.8+ then the joint limits in the INI should allow you to limit the angular joints.
Your setup is a good example of why you might need separate and different axis and joint limits.
