Preparation for torchtable-workgroup meeting on 23.05.:

Suggestions for the long axis:

- supportet Rails [1] would be nice for better stiffness and rigidity, . Makes a price difference of about 20,- EUR or less per m .

- Universal Controler: Powerlolu as stepperdriver for heavier loads ?

* Was already discussed on OSE in 2013, see [2]

* sources are available at 
  GitHub [3] and 
  Upverter [4]
  Allegro [www.allegromicro.com/~/media/Files/Demo-Boards/Schematics/A4989-Demo-Board-Schematic.ashx?la=en&hash=40B890CAB3B9129C93632BB4FDD6CF5E7FC75782].  

* new breakout board from OSH park at [5]

* I tested them already [6] [7] in combination with RAMPS and so far they seemed to work well.

* Instead of one 1"-shaft we coud use two 1/2"-shafts to resemble the recent unversal axis design as is.

* Or instead we can use just one 1"-shaft and place the stepper onto the carriage (like shapeoko) ==> simplyfied end-pieces (they are only needed to fix the belt).
