Hi,
I just received my delta arms from tridprinting.com with traxxas joints and I see that the sideways motion of the joint is only about 30 degrees which is only enough to reach the the outer limits of the frame but isn't able to go further. This limits my print surface from 50cm diamter to 30. Is there an effector that adds another degree of freedom the joints or am I limited until I buy magnets?
Cheers

Im using parts of the cherry pi already, so I had this on my list but with this being my first delta I decided for the easier complete kit of arms, all glued and ready. This makes of course a good case for magnets for my next upgrade but for now im stuck with traxxas.

the carriage they are connected to should be is well above the effector, so the actual angle of the arms relative to the carriage and effector is less than 30 degrees

I dont think the vertical position changes the relative angle of the horizontal movement. Its limited to the same angle horizontally not matter where it is vertically.

In your foto is that the maximum position your arms can reach? If that is the case you could have a bigger bed if you had more reach right?

The print area of a delta is not a circle. It's just convenient to make the bed round.

In your diagram, it's not possible for the arms of the lower left tower to reach the effector position shown.

I disagree - it's entirely possible, unless the arms are too short. Bear in mind that the diagram is a 2D projection of a 3D structure.

... but if you take the rule of thumb that the arms are 3/4 of the triangle side, then the distace from one tower to the opposite triangle side is roughly the arm length. as here in my case
