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] and Balestrino [7].
* new breakout board from OSH park at [8]
* I tested them already [9] [10] 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).
