Calibration and Homing
Manual and automatic approaches
Manual Calibration
- Move FarmBot to the desired home position.
- Press the , , and buttons in the Hardware widget on the Device page.
FarmBot will now set the chosen location as the origin (also known as Home
, Zero
, or (0, 0, 0)
).
Automatic Calibration
Run an axis calibration to let FarmBot determine home and the length of the axis. Either endstops or encoders must be enabled in the hardware settings widget for an axis to be calibrated.
Use the hardware settings widget to home and calibrate the length of each axis.
, , and buttons in theUse the hardware settings widget to home each axis.
, , and buttons in theWith rotary encoders (included in FarmBot Genesis kits)
FarmBot moves in the zero direction of the axis until the rotary encoders detect missed motor steps when the axis reaches the end. This location is recorded as zero for the axis. If performing calibration in addition to homing, FarmBot will move the opposite direction from zero and record the distance traveled (length of axis) when the other end is reached, and then move back home.
With end-stops (DIY option if not using rotary encoders)
FarmBot moves in the zero direction of the axis until the end-stop triggers when the axis reaches the end. This location is recorded as zero for the axis. If performing calibration in addition to homing, FarmBot will move the opposite direction from zero and record the distance traveled (length of axis) when the end-stop on the other end is reached, and then move back home.
