Lulzbot Taz Y Belt Tensioning System

Similar to the x-axis, I found the y belt's adjustment/clamping mechanism a bit of a hassle too. For this component, you need 11x 3.8mm M3x0.5 threaded heatset inserts (10 for t-track/sliders and one for endstop actuator), 6x M3 x 10mm socket head cap screws (4 for clamps and 2 for set screws that secure sliders on the t-track), 3x M3 x 6mm socket head cap screws to mount the t-track, and 1x M3 x 50mm socket head cap screw for adjustment. Moreover, don't forget to include the endstop actuator if you replace the original y belt mount. To adjust, first loosen the set screw on each slider, then use the 50mm screw to adjust the tension and finally re-tighten the set screws to secure everything in place. In terms of printing, it's recommended to print at high infill (90-95%) for sturdy parts. I printed mine with ABS at a layer height of 0.20mm using 1 perimeter and 4 top and bottom shells, with 95% infill.
