| + | ==== Y-Axis ==== | ||
| + | The main concern with using a cable chain for the Y-axis is how to make a connection which is both capable of sustaining high currents, can be crimped, and is small to fit into a 3d-printed enclosure. | ||
| + | For this, a suitable option would be to use unisolated cable-shoes. These are easy to source and easy to use with a 3d printed mounting base, which functions as a junction box. On the picture below a first prototype can be seen: | ||
