Hi Bird
Hopefully the base will be poured soon, We have had 40c deg heat this week pretty warm! So the pour was put off.
As soon as that is done the Z axis and carriage will be next. I will document it soon.
Tip.
If you are using linear rails and ball screws, make a definite decision on those first. When choosing ball screw end bearings for a given ball screw there will likely be two different sizes that will fit, Choose the larger size for extra stiffness. If you are not making your own there are also various ballnut mounts available, some steel some aluminium, I choose steel.
I am guessing you are finding that when you add up all the heights of the x axis bearing rails and slider blocks, the ball screw end bearings and ball nut mounts and allow for fastenings you end up with a height problem. The setup does not work well with simple plates unless you stack in spacer plates. One option is to machine the plates from solid if you have the facilities. The design I am working on uses a hybrid of laser cut steel plates, turned pillars and is epoxy filled. Oh! and the carriage is heavy.
If you like post a screenshot of your current design. Everyone faces this problem and it would be interesting to see different approaches.
