the controller will do. If you change “Auto-Return” to “No”, the rail will leave the camera at its
final position after it completes the stack.
9.9 Polarity
We have a pretty good idea of how most of our customers will use our equipment. Sometimes,
however, you get creative with our gear – we love that! Polarity is just for those special
applications. If you reverse-mount our gear forward isn’t forward anymore! If you press the
“Polarity” button you can change it from “Normal” to “Reverse”. Now forward is backward,
which for reverse-mount gear is exactly what you want and sanity is maintained. Another
perfect example is for the pan/tilt system. If the tilt rotary table is rotated 180 degrees on the
pan rotary table, the forward position is now backward. You could always rotate it back
around, or you could change the polarity.
9.10 Shutter
This configuration shows which shutter output activates when this axis completes a step or
action. Since the X-axis is used for stacking, you would normally just have the X-axis set to
activate a shutter output. There are some applications though where you would want to have
other axes activate a different shutter output. Here is one example if you are doing X-Y
stacking/scanning. At the completion of a full stack you could have the Y-axis activate its
shutter output which would activate a remote device to do “something”. This allows external
devices to count, move, or advance prior to going back to the X-axis. Extremely flexible.
9.11 Rail Dist/Rev
This is the distance the rail will travel per full revolution of the motor. This shouldn’t be
changed for use with our equipment but it may be useful for custom applications like attaching
a motor to your microscope.
9.12 Rail Backlash
This setting lets you adjust the amount of backlash compensation that is applied to the macro-
rail. When the motor reverses direction there (in most applications) will be some “play” in the
mechanical drive mechanism. StackShot 3X has the capability to compensate for this gear
backlash “play”. Backlash compensation will apply any time the motor changes direction. This
backlash setting is based off of an average of rails. If you are doing small stack step sizes (less
than 100um) you may need to adjust this parameter.
9.13 Rotary Speed
This is the maximum rotation speed for the rotary table. Why not always run at the maximum?
There are two parameters that determine the maximum load that the rotary tables can spin.
First is the torque applied, and second is the speed you are moving. The amount of torque that
