Also congrats from my side!
Glad you take the time to move forward. Zcorp and co. will hate you 😛
I like the rolling spreader, but does it maybe rolls too fast? Also should it not be rolling in the opposite direction?
I personally think the best way would be to mount a small stepper to the roller to be able to adjust the speed and rotation of the rolling.
Apart from that, i am really happy that you started to improve plan b again. Can’t wait to build one.
Wishing you healthy days
