Since the most recent update has been pushed out, the rotary encoders on FarmBot have stopped working reliably. It started when the steppers kept trying to move even after hitting the belt clips on the x axis. I was able to navigate around the issue at first by toggling from 1.3 to 1.4 firmware for the Arduino and then I had to disconnect from power and run a new calibration sequence.
Things had been working fine, but it suddenly stopped in the middle of testing a watering sequence. The FarmBot was then showing that it was in the home position even though it was stuck in the middle of the x axis. I have found the the rotary encoders for the x-axis are the most unreliable for some reason. Is there a bug in the firmware? Do I need to recalibrate after powering down and on again? Please advise.
