Required Tools:
- 2.5 mm hex key
Time Required: About 10 minutes.
Difficulty Level: Medium
Maintenance Period: Rarely, when you suspect a belt has been compromised or when prints are looking shifted.
Caution: Over tightening may result in damage
Comments: The Infinity 3D Printer is tuned and calibrated before leaving our facility, over time(1-2 years) the belts may stretch or the prints will start to look shifted. Belt tension is something that you will rarely have to do. The tension can depend on ambient operating temperature or wear.
Steps to increase the X-axis best tension:
- Locate the belt tension plug with the brass insert inside the x-axis belt clamp mount. There is a 50 mm screw going through the x-axis belt clamp mount and the belt tension plug as seen in the figure below.
- Using a 2.5 mm hex key, slowly turn the screw in a clockwise direction and notice the belt tensioning. You will reach the perfect tension when the belt will vibrate 5-6 times when strung. If you can hear the vibration, the belt is too tight. If you can hold both the top and bottom of the belt together with little pressure, it is too loose.
Steps to increase the Y-axis belt tension:
- Turn the printer Off and allow it to cool before continuing.
- Manually move the Extruder Assembly to the R/H side.
- Place padded material to the right side of the printer.
- Rotate the printer on to its right side so that it rests on the padded material.
- Slowly pull the Quick-change Build Platform towards the front of the printer.
- Look through the access port on the bottom side of the printer to locate the Y-axis belt tension plug.
- Using a 2.5 mm hex key, slowly turn the screw in a clockwise direction (to increase tension) and notice the belt tension increase. You will reach the perfect tension when the belt will vibrate 5-6 times when strung. If you can hear the vibration, the belt is too tight. If you can hold both the top and bottom of the belt together with little pressure, it is too loose.
