Great question, the main reason was to make the assembly easier and so gain more torque from the 2nd motor. So turning the driveshaft from a single NEMA17 motor caused movement issues that were reduced with the double motor setup. Here you can find the Changelog.
First of all, I’ve never had the intention to grow vegetables in first place as it was more like a hobby beside 3d printing and cnc milling. The device is still operating and grows things every year, but its not effective to be really efficient. Each harvest is just nice to have, but nothing you can count on. Right now the device is placed directly on the ground without a raised bed, thats probably one of the biggest reasons why plants don’t like it that much.
