CAUTION - WORK IN PROGRESS
If you happen to read this, beware - this has not been validated or tried out yet. So far, it is only a theoretical model.
When setting out to build my own delta printer, I didn't find exactly what I was looking for, so - like many other people, many of which have considerable more experience than I have - I decided to design my own version, with the following design goals in mind:
- Use the MakerSlide system with V-shaped wheels for the vertical axes.
- Use a magnetic bearing system somewhat similar to the one designed by Bert Broeren, that is, the magnets do not have to hold the weight of the effector.
- Keep the effectors easily exchangeable to support different tool heads - various 3D printing heads, maybe a small motor for PCB milling or a laser engraving module at some time.
- Create an enclosed build volumes - for stable printing conditions, to prevent chips from flying all over the place when milling and to contain the fumes when laser engraving.
- Create a parametric design to be able to determine (and change) the sizes of key parts later on.
- Keep the entire design open source, and use FOSS wherever possible.
At the current stage, the plans are incomplete and unproven, and any input is welcome.
