Guides for installation and assembly of the LulzBot line of products made by FAME 3D LLC.
On the SD card with the machine, run the gcode titled Z-Belts_Measure-Tension.gcode
This will level the X-Axis, place the Z-axis in the measuring position, and turn of X/Y motors so that the X/Y axis can be placed as needed.
If the gcode is not available or the machine is not yet fully assembled, simply move the axis by hand towards the middle of travel. Ensure that the slack side of the belt is not interfering with any printed parts, this will provide inaccurate measurements.
To begin, power on the meter by pressing the power button.
The currently selected configuration will be displayed once the meter has powered on.
In the top left corner of the display, the currently selected configuration set is reflected "S No00"
For Mini 2 we will be using S No02 for X/Y Belts and S No03 for Z-Belts. This is because Z-Belts on the Mini 2 have a longer span than X/Y Belts.
To select a configuration set, simply press the corresponding number on the meters number pad.
Once the appropriate configuration set has been selected, press the Measure button, the meter is now ready to measure belt tension.
Ensure S No02 is selected on the Sonic Tension Meter.
With the X/Y-Axis in the middle of their travel, position the microphone of the meter next to the long "slack" side of the belt.
Strum or pluck the belt, almost like playing a bass guitar. The Sonic Tension Meter will listen to the frequency of the audible vibration and calculate the belts current tension in Newtons (N)
Wait a few seconds between strums and ensure that ambient noise is low enough not to interfere with measurement. Talking while taking belt tension measurements will provide inaccurate measurements.
