Here is the rewritten text: Humans can now home on both the Z-axis from "Below" and "Above"! I'd like to explain: With my "Variable Endstop", I can quickly adjust for differences in print head height, whether it's due to different print heads or noses. This setup eliminates the need for a bed level sensor, which takes up space and adds weight. I prefer homing from above because I use interchangeable print heads. In about 3 minutes, I can swap out my entire print head with a new nose size without needing to relevel the bed. All I have to do is adjust the bed height using the dial and it's done! Bed leveling is only needed once, as the alignment doesn't change. The lower endstop isn't crucial for me, but it does prevent the print bed from descending further when the device starts up without homing. If you home from below, it's the opposite. To assemble this setup, I simply used a spring, some screws, and a square nut. You can also build an entire 20x20 rail system if you want; I just used my scraps. Have fun building, and then enjoy the added comfort!
