I just launched a kickstarter project of special interest to all Delta printer enthusiasts.
Its a single low cost linear module that is designed for both cartesian and Delta configurations,
using a precision aluminum extrusion for housing/guide/motor mount/carriage.
Its motion is driven by precision 4mm/revolution ball screw and 200 step motor for a net linear motion of .02 mm per step (less with micro stepping of course).
A Delta machine can use 3 modules as tower/motion/60 degree mounting, so becomes very simple.
I want to thank see-me-cnc for getting me interested in Delta machines, and if the project funds, I hope I can entice them
(or other Delta manufacturers) to design a higher end larger machines using the modules.
If you would like to support it, thanks! I'd encourage you to spread the news to other maker forums and groups.
This takes 3 custom molds for 2 extrusions and an adapter to keep part count and machining low.
If the project funds future versions of the modules will be possible at lower costs.
As is, the kickstarter award for 3 1 meter (35 inch of motion) modules is $730 plus shipping.
Please spread the news!
