Re: 3DR "Simple" Delta Printer
In the X-Y plane, you can get this effect from micro-stepping of the extruder. Its commonly called moire effect, where a repeated 'waviness' happens as the lines are extruded. This is caused by the...

I believe the "curve" you're seeing is also a Moire pattern, which is a result of the stepping from the three towers. When you're dealing with a Cartesian printer, the circles require moving the X and...

I really like the idea of using magnetic connections for my custom delta build. I notice how much play there is within each Traxxas 5347 joint I'm presently using and don't like the idea of using...

Alternative idea to the prismatic(slider). To alternate between multiple hot ends, mount the hot ends on a revolving plate, and splayed as you have noted. The plate is at an angle (cam), and revolves...

To keep the weight off of the hub/end effector, you can use a bicycles break cable (solid wire cable, not a braid) to rotate the plate (hot ends). Kind of like how the Bowden cable works. The proximal...

Yea I saw that design as well, I really like that too. I was thinking about perhaps adding that as a method of selecting the angles for the pivots on the sliders. I realize the pivots on the sliders...
