Changing U axis to home on lower end instead of high end.
-
I have finally gotten around to installing my second extruder onto the U axis. Both X and U axis can pass by each other freely. I am trying to get both axis to home on the lower end instead of X on low and U on high. I don't see anything in the M574 command to tell it otherwise.

I figured it out. Change the U2 to U1. I feel sheepish now.
