AutoLevel with Servo and Photosensor

thingiverse

I attempted to craft an extremely basic AutoLevel Sensor. You can print it without any supports and you only need to print two parts. Furthermore, a rod, optical sensor, and servo are also required, but that's all there is to it. In my case, the rod I used was a standard carbon fiber rod (2.9 mm in diameter). Since you will have to drill the rod guide anyway, you can simply adopt it to your rod's hole size. However, it should be around 3mm to fit the probe perfectly. Once everything fits together properly, just attach the probe to the rod by gluing them. Be extremely cautious as you only need a tiny amount of glue for this task. I recommend applying the glue using a toothpick to maintain better control over the application process. Depending on the type of PLA/ABS material used, you might have to paint the probe with something like black Edding. This is necessary to ensure that no light can pass through it. In my particular setup, I was able to achieve a minimum accuracy of 0.02mm in terms of repeatable performance. With such an accuracy level, you will be able to obtain outstanding AutoLevel measurements. Have fun working on this project! By the way, I would like to extend my appreciation for the amazing inspiration behind this design, which can be found at http://www.thingiverse.com/thing:490024 – A truly incredible piece of work!
