have to press the button when the desired number for that digit is displayed. Once all digits are
modified, the BB023 will return to normal operation.
IMPORTANT
: If you accidently press the button while a spool is displayed and do not want to edit its
current length, simply unplug the power from the display unit before completing the editing. Then after 1
second plug it back in. The spool length will be restored.
Mounting the sensor unit
Every model of 3D printer can require a different mounting method. The key point to remember is that
the sensor needs to be able to pivot freely when mounted. You can use the given example of an
AnyCubic Chiron printer as a guide. Mounting the sensor will require you to make a mount for it. As
shown in the next picture, a combination spool holder and sensor mount was 3D printed for the Chiron.
This is available on thingiverse.com or www.brownsbrain.com. A small screw was used to hold the
sensor unit to the post of the mount. The sensor unit can freely pivot on this small screw because the
diameter of the screw is smaller than the diameter of the hole in the sensor unit.
