Work done on stepper motors and casing
Shaft:
New shaft needed to fit the casinghave been made, but the lathe is not accurate enough, and drills an uneven hole.
Issues with old shaft:
- profile:
- Too short (has to be 11.8)
- top down:
- hole off center
- hole too large
...
stepper motor holder top down
magnet-holder (white):
...
- too wide to fit stack
magnet holder profile
...
new models have to take this in to consideration.
Waterproofing:
Group has concludet concluded thtat filling the housing with oil is the best solution for waterproofing, as the shaft it will make it be dificult to fully waterproof the surounding area of the shaft.
Coding:
Formated code to work with teensy, can be found on github:
