Yesterday I received the LCD-shield and was able to complete my controller.

So, I have added the controller-slat to my macro-slat and have created the Macro-Station :-)

Main features:
1.) Arduino based controller

2.) Open interface programmed easily in C++

3.) Standalone mode and connected to the PC
4.) LCD and 6 keys for the entering of the data
4.1.) Shutter Speed

4.2.) Time for loading of the flashes

4.3.) Aperture for the calculation of the step-size

4.4.) Start point

4.5.) End point

4.6.) Run stack

5.) Connection to the camera remotely by the IR
6.) Size of the steps calculated on the basis of the aperture
7.) Number of the steps calculated on the basis of the distance between the two selectable points ( and step size detected before )
8.) The gear-box 100:1 enables step-size in nano-meters
8.1.) NEMA 17 step angle of 1.8 degree ==> 200 steps for the 360 degrees
8.2.) TB6560 16 micro steps, 1.4 A
8.3.) Gear-box (99 + 1044/2057): 1 ratio
8.4.) Full rotation 318424 (200 * 16 * 99.5075352455031599) micro-steps
8.5.) Mitutoyo screw: scale 25 positions a 0.0254 mm
8.6.) One full rotation ==> movement of the rail = 0,635 mm (25 * 0.0254)
8.7.) Full rotation of the micrometer screw shifts the carriage 635 micro-meters.
At the moment I’m implementing a photo-sensor for the checking if the flashes have fired.
If not then the stacking-session will be stopped.
