Also, there are some updated parts lists and drawings that highlight most of the differences.
Note that each post name will have the H-1 Assembly Manual chapter number so you can cross reference easily. I'll do these in the same order as the original manual if possible.
The primary differences in the H-1.1 are:
- it uses linear rails and bearings for the three axis. These are higher precision the the H-1's rails and bearings
- it comes in a choice of colors (!) with complimenting black parts
- it uses precision bearings for the belt idlers instead of plastic bushings
- it has an updated Hot End
- it has a lower parts count for easier assembly
- it comes with cool adjustable belt clamps/tensioners
