The [k] command allows the setting of the number of steps that the plunger travels after
initialization. This is to minimize deal volume. The syntax for this command is:
[k<n>], where <n> = the offset in steps from zero position
<n> = 0..80
<n> = 0..640 in microstep mode
Under default initializations, the plunger moves upward until it contacts the top of the
syringe, causing a forced stall initialization. The plunger then moves downward and
upward, leaving a small gap between the syringe seal and the top of the plunger. This
small gap was designed so that the Teflon seal does not hit the top of the plunger each
time the syringe moves to the “home” position. This maximizes the life of the syringe
seal.
The [k] command must be followed by the Initialization command [Z], [Y], or [W]. Each
time the unit is powered down, the “k” value will return to the default condition.
For example, to offset 10 steps away from the zero position, send the following
commands:
1
k10R
2
ZR
