There are several types of 3D scanners. With one exception, they all use a camera to take pictures of something. Some […]
I had a request to upload some stacked files for a Prusa MK2.5S. I sliced them with Cura (for the MK2, but I think it should be close enough), and the equivalent code I’m running on an MK3 is working fine. I’ve got two variations (and the STL file). One doesn’t use a brim, and […]
