Endstops and electronics

A distinct item you have not seen added to this design is endstop switches. You can use exactly the same switches that you acquired for your 3018 and mount them on the extrusions as you see fit (do not use the switches that come on rod mounts; those switches are fine, but their mounts are not). I haven’t done this here as they are not essential, and installation will depend on what you buy. I suggest you place them at the 0,0 position, and so the switches are at the left at the rear of the machine if you are looking down the Y axis from the X-axis tensioner. If you look at Figure 8.1, this would be the corner of the machine at the bottom left.

For electronics, you will need the usual components – notably, the board, power supply, and optionally, an emergency stop switch and LCD controller. You can 3D print or fabricate a box to enclose the electronics and mount the box against the feet of the machine. If you enclose your machine, you can run...
