    • Run the other belt through the drive gear on the other corner.

    • Use paper clips or zip ties to help force the belt along the correct path as necessary.

  6. Run the belts down the other side through the X/Y joint and front idler. Run the belts down the other side through the X/Y joint and front idler.
    • Run the belts down the other side through the X/Y joint and front idler.

  7. Finish the run at the carriage.
    • Finish the run at the carriage.

    • Double check that your belts both follow the correct path.

    • Ensure tensioners on both sides are completely loose.
