I used the values out of the stepconf wizard. I will try and change them and see what happens.

That's not going to cope well with bipod calcs.

Looks like I need to do some more reading. When in joint mode does the scale not matter?

I am not saying that your scale is wrong, just that it looks unlikely.

I assume it needs to translate to "steps per inch of string",

The problem might be your kinematics setup. I don't think it is possible for L0 L1 L3 L4 to all be zero, and that is probably messing up the maths.
They are the other sides of the triangles where D01 and D34 are the top horizontal sides. It is impossible for L0 + L1 to be less than D01 and typically they would be about the same value.

Yes the kinematics was wrong. I also backed the scale way down and it is still giving me a joint following error?

I suspect that it might not be the cause of the following error, but the scale ought to go up for conversion from mm to in.
It is steps-per-unit, and it takes more steps to haul in an inch of thread than it does a mm.

I think you need to go through your iNI and work out whether every number is the _right_ number.

Ok I ran a program and it works. But the right and left is backward on the A-B axis

I assume that A and B are angle from vertical and from horizontal?

I am not entirely sure how one would define what the sense of those angles should be.

Is the problem a mismatch between CAM and CNC?
