readback of the motor encoder (in the example below, it is 2048). Manually rotate the
encoder until the readback is 1000±100 (i.e., in the range 900-1100) and then secure the
encoder to the drive shaft.
Repeat the calibration procedure above but now, when TX hits the outer mechanical stop,

The program switches to graphics mode and draws the Encoder Vs Distance calibration grid.
It moves the TZ motor to its topmost position and then steps the TX motor in by 1"
increments until the inner mechanical stop is hit (while simultaneously rotating the C-arm to
keep the table and C-arm from hitting). The program plots the encoder data during the scan
(in raw encoder units, 0-4095).
