> hi, I tried it too. I switched to 1.12, it took a while before I got the hang of it, but I’m calibrating 800x400 with a 5x5 grid. Fitness ended up around 0.85. Frame 4.4m x 3.6m concrete floor. When moving in one direction, the belts sag in the opposite direction, when I go up there, it loosens so much that I have to stop so they don’t get tangled. I have both 1500 forces.

This is the same thing I am seeing
