WebbRemove lead screw and install through the top of the nut until it seats into the coupler. Also, this is a great time to get your lead screw aligned. Thank you so much for this advice. It is perfect. Don’t back drive the stepper it turns into a generator and can cause the magic smoke to escape. Remove screw. WebbScrew axes which have translation along a line only result in reflection conditions along a line in reciprocal space. This is shown in the table below: From the table, it can be seen that if the translation component of the screw symmetry operator is 1/ m, then the reflection condition is of the form m × n. Also, in contrast to the reflection ...

The X one is independent, while the Z is coupled and moves together with the X, and lastly the Y lead screw is coupled into the Z plate. To simulate the dynamics, I have created a Simscape model.
