Hey everyone, I've been considering ways to stiffen up the carriage on my mini-ox build, and I've been searching for ways to move the spindle closer to the X-rails. Is there any reason why nobody uses this sort of design for the z gantry? This eliminates the need for the spacer blocks, moving the whole spindle closer by 12mm. Without spacer blocks, the wheels are also stiffer and can probably bear more compression. This also opens up the possibility of using ball screws or brass lead nuts, since they're typically much thicker than the 12mm nut block. Anything I'm missing about this that makes it worse than the current designs?
