3D printers not getting any better....

Precision might come from the new Core XY printers, which right now I think are only the CraftBot and the F306 printers.

I had to go and read about this and after sitting looking at it for a while it occurs to me that oyu can easily do XYZ with two steppers and make a frame that can be quite portable and stuck to walls for drawing or printing onto something else where your printed part becomes part of some bigger machine and removing one stepper out of three means a big cost saving.




If the belt from stepper 1 is made continuous around the big red toothed gear and smaller idler pulley then X and Y movement remains the same but with stepper 2 locked and stepper one rotating you can drive a Z movement on the red pulley.
