These spacers can be used to correct the IR filament sensor. Just stack them below until reliable readings are achieved. I am also including the f3d file in case anyone wants to print a single, final spacer to suit their exact measurement needs, or simply to reduce wasted filament. The 1mm worked perfectly for me on both kits.
Included:
.2mm
.5mm
1mm
Range Steps: .2mm, .5mm, .7mm, 1mm, 1.2mm, 1.5mm
If you exceed 1.5mm, there is probably a separate issue...please contact Prusa support.
The sensor information can be found by navigating the LCD menu:
Support > Sensor Info
"1" means that the sensor detects filament. "0" means that the sensor thinks the filament is empty. Cut a 15-25mm piece of filament, angle the tip, and use it to test by inserting/removing just far enough to move the ball, but no far enough to catch in the gears. Proper height spacing should reliably toggle the 0 and 1 reading with no misses.
If you print this and it works, please post the size(s) you used to help others.
