Btw, you can mix the acme rod pitches as you need to but I suppose most people don't since there is usually enough pieces left over to make the z axis lead screw. The settings you need to use for each lead screw pitch are not difficult to figure out. You just enter the threads per inch and 1:1 gear ratio if you connect the lead screw directly to the stepper motor shaft with a coupler or use a belt drive with same size pulleys. Software settings make the hardware move the correct distance.
