I've heard comments mentioning that I may not have sufficient Z height. I've never built a machine like this much less been around them so the likelihood of me painting myself into a corner is pretty high. Funny thing is I have been worried about the Z height, only I have been concerned that I have too much room, not too little. The good news is the bed can easily slide up or down the legs and be attached right in the sweet spot.

Here is how it measures out today...

There is 31mm (~1.25in) of space between the lowest tip and the top of the steel. The max travel of the fully extended tip is 21mm, which leaves me 10mm (just under 1/2in) that my board mounts will need to lift up the board (at a minimum) so the tip can reach the board. Same goes for parts. Since I will probably be designing/milling my own mounting system I can really make them however thick they need to be, but I didnt really want them to be much over 1/2 inch. Does this sound reasonable?
