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] and
  Allegro [5] and
  Cuteminds [6].  

* new breakout board from OSH park at [7]

* I tested them already [8] [9] 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).
