If you want to verify proper load of all five filaments before print, select
​
LCD Menu - Load
filament - Load all.
​
The MMU unit should quickly try loading and unloading all 5 filaments
one after another without any user interaction. After the last position, the LCD Menu should
quickly try loading and unloading all 5 filaments one after another without any user
interaction. Green LED should signal success of load after each position.
5.4 F.I.N.D.A explained
F.I.N.D.A is an older design P.I.N.D.A probe repurposed as a filament sensor. When the
filament is pushed through the selector, it raises a stainless steel ball. Its movement is
detected by the F.I.N.D.A. There is a small red LED light on the back of the probe. As soon
as the filament is detected, the light turns off.
When the filament is removed, the stainless steel ball falls back down. Please note that the
ball is pulled down by gravity, that means the filament sensor won’t work if you for whatever
reason turn the MMU2 unit upside down.

6 Calibration
Since the assembly of the MMU2 requires the printer’s extruder to be
disassembled in the process, it’s very likely that your printer’s Z-axis is now
shifted. It’s essential to re-calibrate the Z-axis and run the First Layer
Calibration routine before you start printing!
