Use Arduino , AB encoder and L298N.
It's a nice projtct.
I get many insights from it.

Insighted by DC motor closed loop controller ,I begin to prepare AnanasStepper 1.0.
I built this Four Brothers,their schematic diagram is below
4.400p encoder (Not here)

After finished my prototype of AnanasStepper 1.0 .
I turn my delta 3D printer to a closed loop controlled 3D printer.
I use this structure to mounter the encoders.
the model is here
Then I test the functon.

I test the closed loop printerhttp://v.youku.com/v_show/id_XMTUzODI0NDE0OA==.html
the printer can back the right position , After I draged the carrier to a wrong positon.
And this is the testing example of my 3D printer.
And this the open loop one.
It same the well turned AnanasStepper 1.0 CAN avoid losing steps.
But there is some bad feature.For examples,there is over shoot ,because AnanasStepper 1.0 Use PI mathod ,So It is hard to get a very perfect performance.
So I begin to develop New version!
Then AnanasStepper 2.0 came to stage!!

AnanasStepper is based on arduino
As5600 and As5601 encoder.
A4988 and Drv8825

Redesign the PCB ,With the A4988 embedded。
Drivers embedded makes things simple.

AnanasStepper 1.0 makes Kossel to a close loop printer

Test AnanasStepper 2.0 3 Axis gang control.

New Board Tests Successfully!
With Driver Embeded,It's more easy to assemble.
