Here is my config.g
I have the original arms, and yours is showing 291.06 for diagonal arm length. Mine is 340.5. Is there a configuration macro that can change that?
Now that I think about it, I crashed the machine against a part I forgot to remove, and had to recalibrate. That's probably when this problem started.
I'll do some more Googling on arm length now.
