⬢Release the screws, bring the X-end closer to rods and thus decrease the overall tension.
⬢Tighten the screws, X-end will move apart, the overall tension will increase.
⬢It's recommended to mark the distance of 2.5 cm (0.98 inches) from the end of the PTFE tube before the insertion to the extruder. Both ends are symmetrical.
