In some cases you might want or need to use multiple software packages; for instance, you might pick one for capturing and animating the images, another for capturing sound and a third for editing all the elements into the final film. You might have to remove a small nut at the back of the shaft and remove the shaft itself to reach the rollers. Then reach behind the drum, motor pulley, and idler arm pulley. You may have to remove the dryer belt to reach it. Any difference in belts can change the speed of the drum and cause problems with other dryer components. Worn or broken belts can also cause a humming noise.
