Starting to design out my build, looking for critique

[Chrono]

You could also think of using rotating ball nuts 2Mtr is a long way with 16mm screws

How would I mount the rotating nuts? I guess I would need the motors on the gantry then? Would that also mean that I would either need an elaborate timing belt setup spanning the gantry, or use two motors?

I can also just use 2010 or 2510 ballscrews and get a stronger motor for the X, which is something I am actively thinking about. According to the motor calc sheet, the Y and Z are perfectly fine as is, at 7.5m/s rapids, using 1610 ballscrews.


On another note: After thinking more about the changes I talked about and talking them, and other things, over with my colleagues, I am remaking the CAD file from scratch. While doing that I am also reworking everything to be 100% parametric, which is taking a while, but is paying off massively. Basically fixing mistakes made the first time around.

Current progress is the following: The table and X axis are done, except for the X axis ballscrews. The Gantry and Y axis are complete. What is yet missing, is everything concerning the Z-Axis, pending a complete revision, Motors and timing belts, and E-chains, that I want to account for. All in all, it is progressing nicely.
