Pardon for the uninformed interruption I am not sure why moving back to a geard-driven system with an axis or rotation which is fixed would not be simpler; That is, where the arms are both of the same radius and pivot on a central point. The chord, or distance between the base and the effector then increase in a manner predictable by simple trigonometry. That is, for the same radii, Chord lengby LShearer - Delta Machines
I would like some help on where to next, if you can. I have a second hand sanguinololu 1.3a which I know has previously worked within the current setup, under yje care of an IT/Electronics professional. Thus far I have 1) Connected external power I have connected to the external power slot, 12V, from a 800W computer PSU. At the moment it has green-ground shorted on the 20/24 pin header. 2) Estby LShearer - Sanguino(lolu)
I would like to share an idea I'm incubating, I would like to look at making a hybrid between the galvo-based Form1 and the cartesian-movement based mUVe1 - that is, a near-UV curing resin printer that uses a combination of mechanics and electronics to expose 1-part resin to UV light to make parts. The intended advantages; 1. UV-curing resin, cheaper that light-curing as used by some DLP 2. Outby LShearer - Developers
