The Bantam Tools Explorer CNC has two o-ring belts that connect the motor to the spindle. We designed this for easy replaceability when there is noticeable damage or slipping happening due to belt degradation or wear.
You can order replacement belts by contacting support@bantamtools.com
Follow the steps below to replace the o-ring belts:.
- Power off your machine. Let it cool down if it has been running.
- Remove the upper belt pulley cover. Pull slightly to allow the front to disengage the tabs, then remove from the back tabs.
- Remove the existing belts by starting with the top belt.
- You can use your finger or a wood/ plastic tool for this. Using a wood or plastic tool with 3/16” or less diameter end might be a little easier than using your fingers. Wood or plastic will not damage the aluminum pulley. We used a chopstick in the below videos 🙂.
- Slowly pull the belt outwards and upwards from the side while rotating the front belt pulley. This should allow the belt to ‘escape’ the pulley track. Once loose, remove the belt.
- You can then repeat the action to move the lower belt to the upper track, and again to remove it completely.
- Reverse the process with the 2 new belts
- Align the belt on the lower rear pulley, stretching the belt slightly as you engage the front pulley and allow the belt to fall into the proper tracking position on the pulley.
- Once the lower belt is in place you can proceed with installing the top belt using the same method as above.
- Once both belts are in place rotate the spindle by hand to make sure the belts are tracking on the belt pulleys correctly
- Reinstall the polycarbonate pulley cover
- Reconnect your machine to your host computer and power it back on.
- Open up the Gear Icon Menu and click the ‘RUN WARM-UP ROUTINE’.
Once the warm-up routine has completed, you can continue with regular use of your machine.
