Currently building a chubby mini Kossel. Any others of a similar bent?

Not at this time, but curious.

You call yours 'chubby', what do you mean? What advantages does it give you?

The nominal mini Kossel has 240mm sides. I want to increase the print volume by making these 300mm and extending the effector arms and, of course, updating the firmware (Marlin) to reflect the new geometry.

I am still in the tuning phase of a scratch built Delta loosely based off the Kossel. While I am getting some decent prints I still have issues with the end effector jittering from step pulses from the motors. I am leaning towards the length of the arms causing this. The reason why I bring it up is that you might consider that when scaling up the size you may need to account for it in spreading the smooth-rods apart and/or other upgrades to keep things moving smoothly.
