Belt-Tension-Checker

thingiverse

Test to find the ideal belt tension setting for my CR10S4. I printed adjustable screws for the X and Y axes without knowing what works best. This design will test in both X and Y directions as well as 45-degree diagonals, plus a 2.5-circle curve. I began with low tension, which was too low in my opinion. I tightened in small increments after every 10mm of Z-height while printing to observe the different steps and their effect on ringing and other issues. It turned out that I needed to lower the belt tension compared to what I normally assumed to minimize ringing on both X and Y axes. This test can also be used when testing various jerk, speed, and acceleration settings by changing them at known regular heights while printing.
