Hi there.
I managed to get myself to step 11B following the instructions and am setting my Maslow up with the chain off bottom configuration.
However, when I went to set the length of the left chain, the motor rotated clockwise, not counter-clockwise as expected and stated in 11B - step 3
I thought maybe i’d selected the chain off top option so I checked by setting the right chain, the motor rotated clockwise as expected.
I then repeated the whole calibration process again to try and rule out any problems I may have introduced in my rush to get cutting but it did the same thing again.
I then did it a third time, this time deliberately with the chain off top to see whether that had any issues but it fed the chain out exactly as it was supposed to on both sides.
TL;DR When I go to set the length of my left chain in the chain off bottom configuration, the gear rotated clockwise instead of counterclockwise.
