In the latest revision of the Wanhao i3 it has been discovered that there is a design defect. It´s caused by a crimp cable inside the drag chain. This defect may in worst case scenario cause the cable to break which in that case causes a heating failure or a circuit short.
To fix this potential problem there is a short description below, it will take about 5 minutes to fix and is very easy.
We do recommend that you take this action before you use the printer for the first time to make sure that there is no unnecessary wear and tear in the future.
We do of course apologize for this inconvenience and we hope you will have many hours of printing ahead of you.
If you should have any questions what so ever about this, please don´t hesitate to contact us and we will help you.
