Hi,
what are the exact planned distances in mm for the different color lines, see picture below.

Red line bearing spacing distance seems too small for that enormously long Z, doesn't matter that the Z is 3 rail supported. Best would be if is same distance like violet line.
Meaning 250mm is not right here. ~350mm is more sound. Have in mind that mostly and only Lower bearing blocks take the force, so should be up to the task of coping with 900mm extended axis acting as a lever. Proving that with a calculation would be useful. The upper bearing block acts only as lever arm so basically is doing nothing apart from levering, hence the distance here is extremely important.


Why so long Z? Longest reasonably Z IMHO is 500mm. Unless you plan to shape only egg statues . The z assembly will intefere, so i dont see what the benefit will be of so long axis.
