The frame for my test rig is coming along. Still waiting on the mainboard, belts and pulleys. Worth pointing out there are no magnets in this design - the push rods are under compression though the use of a tension spring or shock cord in this case. The same technique could be used for magnetic or spherical bearing type arms to augment the holding power or take up backlash/play.

@fma said in 6 axis delta 3D printer:

@dc42, what about a delta with 2 moving plateforms using the same rails for the 2 sets of arms?

This is very close to what I've been thinking about lately, was just looking around to see if anyone had tried something like this and where they were up to.

What I have in mind is essentially two coupled delta effectors, but this is over-defined so the second set will just be two extra arms that orient a pivoting hot-end.

Anyway, this will be my first foray into the Duet/RepRapFirmware ecosystem, so thought I would say "hi". More questions to come, no doubt.
