Tevo TORNADO - X-Carriage Wheel Tension (X-axis); Y-axis Belt Tension Adjustment

- 9 -
3. Adjust the tension of the X-carriage wheels on the X-axis on the gantry frame.
• Check the tension of the X-carriage wheels. Try to turn the wheels under the build plate
without forcing it. If the wheel turns freely or without much effort, then it is too loose.
• To tighten the wheels, rotate the eccentric nut that connect to the wheel. Use the open-
end wrench to rotate the nuts slightly until the wheels is snug against the X-axis frame.
• The hotend assembly and the belt should move left and right without much effort, and
there should have no front-and-back wiggle or play.
4. Check the tension of the belt driving the Y-axis (under the build plate). The belt should be
taut, with no slack or slop.
• If the belt is loose:
• Loosen the four bolts at the front of the base frame holding the belt pulley.
• Pull the pulley to tighten the belt. Holding the belt taut, tighten the four bolts.
