Prusa i3 Mk3S Autoload IR Fix

thingiverse

When I assembled my new Prusa i3 Mk3S, I found that the filament sensor was not working correctly, so after checking the forums I found some solutions that could work, such as disabling the IR sensor, abrade a part of the "extruder motor plate" or installing a spacer between the extruder and the sensor. As I also had to upgrade another Prusa mk3 to mk3s, I decided to add some modifications to the extruder parts to correct these problems, like smoothing the Extruder motor plate where have the problem with the Fs-lever and reducing the size of the Fs-lever too. After installing the parts in the mk3 to mk3s update, everything worked smoothly. For those who are about to carry out this update and want to avoid these sensor problems from the beginning. Before printing the parts of the update from the official website, try these, they may work as well as they do for me.
