The Biqu Belter suffers from not having a calibrated reference point.
The length of the measuring rod and the self printed tip may not combine to be the same length as others making the sharing of measurements meaningless.
This tool calibrates to 5mm below the surface of the pins.
Do not use the Belter calculator, its not at all accurate or relative to this calibration point.
I use the following measurements to adjust the belts on my VoronV2.4 350mm, your machine may require a different measurement. Please comment the tensions you come up with.
Motors Off
A & B Belts (6mm GT2) - 4.2mm - Print Head all the way to the back middle
Z Belts (9mm GT2) - 5.5mm - Print Head down near the build plate
This would get me close to the tension i got from the Pluck and measure Frequency method.
In the future when i have some spare time i will hang both 6mm & 9mm belts and slowly add weight to make a spread sheet that will correlate to tension expected. I have access to Lead Shot so i can do 1oz increments to build as accurate of a graph as i can.
I may come up with a way to add more tension to the rod in order to get a bit more resolution out of the unit. I just need to find a commercially available spring of the correct tension and length that i can spec so anyone can accurately share their readings.
Note - The belter zeros every time its powered on, so i store it with the calibration tool installed. If the display times out you have to re calibrate the tool.
