You have the line that sends the position commands to stepgen.3 commented out so stepgen.3 does nothing.
And thanks for zipping them up it makes the posts easier to follow when files are attached instead of pasted.

Should be stepgen.3.position-fb, you have an axis 6 but only 0-4 stepgens.
Are you sure that was the error?

You have several errors so quicker for me to just fix them. Also as mentioned before your velocity and acceleration for axis U is much higher than a parallel port can muster so you get following errors. When I slow down the jog speed I have no problems jogging U.

I have movement but got the joint error on 6 probably due to the acceleration. Do I need to change this in the stepconf file or somewhere in the ini or hal file. what are good settings to start out with?

From now on, ignore Stepconf. You have made changes that will be over-writtten by it.
Having said that, the best way to find the velocity and accel limits of the axis is with Stepconf, so create a new, throwaway, config driving you U p-port pins as X and use the "Test this axis" button to figure out the limits.
