ProcedureGantrySetup & CalibrationAdjust
Adjust the gantry rotation speed (servo amplifier, VR1)
Trim the gantry rotation speed at the servo amplifier by turning VR1 on the KGTSM PWB while watching a live rotation-speed readout on a PC, repeating the check/adjust cycle until the reading falls inside the specified range.
