I suspect it has to do with having defined 6 coordinates and then you have 8 axis sections below. I don't know what exactly, what you have doesn't seem to violate anything in the manual and you have DEFAULT_VELOCITY set which controls jog speed. But, I have seen odd behavior like what you describe when I was trying to get the number of joints/axes correct. Why do you have two Z sections defined? I assume you are using gantrykins?
