Apparently I ordered too many 8mm threaded rod online and was thinking and wondering why I haven't seen anyone do this:
Use the rod with locked nut system on the X axis.
Easy, replace one of the rods on the support for the threaded rod, place 8mm nut in the print head and change the motor 90 degrees to turn the rod directly.
I think I'm going to try this. From what I have seen on the Z axis, this should also get better resolution and you won't have to worry about gettting the right tension or having the belt in the way.
Any ideas from anyone before I try it?
