Kinematics and Calibration

Hi, I am progressing at the consept of kinematics, forward, reverse or inverse, but I am confused about calibration, of the L6 arm, SSC-32 and Rios so that the Y=0 plane is like a sheet of paper and then I can crayon on it like I used to in grade 1. ? Let me rephrase:
I am interested in some pointers to documentation or tips on how to set up my arm for use with RIOS.
For example, Y, varies from 3.12 near the arm to -1.03 far from the arm. so can I use (or adjust) gravity compensation to correct for this anomoly? ( even though I would need negative gravity corrections?)
pondering…
P.S how could I tell if it is the shoulder, elbow or wrist which is most out of calibration?
P.P.S if you read this far thanks…

Hello.

I am FAR from an expert but I will try to help you the best I can.

As far as mechanical setup goes, make sure everything is centered and “by the book”. This is very important since you need everything to be in place when all servos are at center.

Then you follow the setup portion of the RIOS manual as far as setting end points and you should be good to go.

I would suggest bolting the arm down to help with some of the bobbing.

Hope you get some more answers. Again, I am hardly an expert and still on the learning curve myself.
