is there a way to move the hot end to the front and center so i can work on it?

Turn the machine off and move it with your hand

I've been told ( and demonstrated) directly from the UM team you can just move it with your hand as long as the motors are "free". if they resist, don't move them.

I move it (with the machine off) by pulling on both ends of the guide rod(s) one axis at a time.

This is good practice as it's a bit more gentle on the printer. However, you should be able to move the print head around just by grabbing it and dragging it to where you want it (which is what I do). If there is significant resistance when doing this there's something wrong. Most likely the axes are not properly square. If they are, the rods probably need some oil. A single drop of sewing machine oil per rod is plenty.

Yes, especially those four rods with the phosphor bronze bearings. The thought of those running dry: shudder
