Some links related to the torchtable height controler:

Working document [1] AD7747 [2] Dummy page (?) [3] Pauls log [4]

Trying to re-use Pauls KiCad-Files run into the problem of beeing an older Version, what means all links are broken, see

• Reimport-problem on older Kicad files
• 

  All default parts are in the newer Kicad version replaced by smaller ones, so the links are broken

This is a known problem and theoretically there exists a way to fix it, see https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/, but its way to complicated to go through this procedure. Meaning, since Pauls circuit is not too complicated its probably far less work to simply rebuild it from scratch.

Preparation for torchtable-workgroup meeting on 23.05.:

Suggestions for the long axis:

- supportet Rails [5] would be nice for better stiffness and rigidity, . Makes a price difference of about 20,- EUR or less per m .

* Instead of one 1"-shaft we could 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).

- Universal Controler: Powerlolu as stepperdriver for heavier loads ?

* Was already discussed on OSE in 2013, see [6]

* sources are available at 
  GitHub [7] and 
  Upverter [8] and
  Allegro [9] and
  Cuteminds [10] and
  Balestrino [11].  

* new breakout board from OSH park at [12]

* I tested them already [13] [14] in combination with RAMPS and so far they seemed to work well.
