3.6 Light Guide Alignment
Light guide alignment is key to your Prot’s vision system to verify and maintain filament
diameter. Every unit is aligned and tested for performance before shipping, but sometimes
things are bumped and moved between when the unit ships to the next time it is turned on again
by you, the owner. Ensure your light guides are properly aligned.
Depending on when your unit was built, you may have one of two variants. One is not better
than the other in terms of function. They both work to align the LED beam of light, but an
iteration was made to improve fabrication and assembly time. The following image details the
two types of light guides:

3.6.1 What you need to check Light Guide Alignment:
● You’ll need two sizes of dowels. Drill bit shafts are an excellent option (use the smooth
shank, not the cutting flutes side).
It’s very important that the dowels are a
consistent, known size - DO NOT use extruded filament!
● ReDeTec uses a 1.83mm and a 2.56mm dowel to align the light guides, but you can use
anything close /- 0.1mm. The larger dowel size is used for the sensor closest to
the nozzle, and the smaller dowel size is used for the sensor closest to the puller wheel.
For reference we will call these the Puller Sensor and the Nozzle Sensor.
● You will also need to be connected to a computer, to use Prot Command Center
(“PCC”).
