Z Axis Changes for V0.04 and V0.05
Assembling the μRepRap V0.04 revealed a minor issue in that the X Stage Flexure now only moves 4mm before colliding with the Z tower. As moving 4mm is "pushing it" with the current Axis Driver, that's not a huge problem and existing builds won't need to fix it, but I've changed the Z Tower design anyway:
I've trebled up those vertical supports to help add rigidity.
Moving on to V0.05 that's all going to need a rehash anyway. The Axis Driver is going to change shape, so I'm not concerned about the bodged nature of this fix.
Current thoughts are to add constraining flexures limiting lateral movement of the pantograph flexure, and only allowing it to move up and down in line with the drive screw. Haven't figured out how to nicely design that yet.
