BOXY Winder Replacement Drive Belt
The BOXY winder is driven by a rubber belt drive. These rarely break, but if your winder doesn’t work and the green LED shows the power and the winder cup rotates very loosely, then the odds are that your winder belt has slipped or broken. Go here to troubleshoot. It could be that the drive belt fell off inside the winder. If this rubber belt is still in good shape, just put it back on the winder pulleys as shown in the video. If not, buy this replacement belt.
