After installing a Microswiss Direct Drive extruder, I had one issue – the print end would not return to its last position after pressing pause. Since I did not use the pause feature often, I was not in a hurry to find a solution. However, I started to really miss being able to make multicolor prints. I finally contacted Microswiss and asked for help. A couple of weeks after back and forth emails, a super-knowledgeable and conscientious person named Paul found a solution. It was a retraction issue in the slicer.
