Because I want to print large things out of difficult materials like ABS or Nylon I need an enclosure. I’ve built some enclosures and they are relatively big for its build size due to the Cartesian printer type. Especially with this huge machine I want to reduce its size by making it a moving portal machine. The standard coreXY systems have a cage in which the core is moved in, as the name suggests, the X and Y direction. This is done with a belt driving mechanism and I looked at several options, but I think that my approach would be the simplest. I don’t think it will reach the famous speeds a coreXY printer can reach, but it definitely doesn’t have to move as much weight as a Cartesian style printer has to do.
It uses mostly 3D printed parts and reused parts from the bed so risks and costs are low 🙂
The video I’ve made about this is this one:
I recently did some tests how well it performed and updated the current version because of a design flaw which I show in that video too
