Setup Tab
The Setup tab lets you adjust the parameters of the MicroTouch unit.
Normally the Min and Max Values are set to 0 and 60000, respectively. This is the full
range of the MicroTouch digital steps (but not necessarily the physical range, depending
on the focuser). If your focuser has less physical range, you can limit the Min and Max
Values to keep the focuser from traveling too far.
The default value of Steps per Tick is 1. This means each position step corresponds to
one step of the stepper motor. This gives the best resolution. Changing this value to 2,
for example, moves the motor 2 steps per position number, making the movement faster
but less precise.
