Ding ding, solid frosty fruity nugs.
Great googly moogly...that is a bodacious cross. "win-win"
not sure about the motion question though? There are six 2in ball casters for each HZ and they pivot on a 6in x 1/2in lag bolt anchored in the centers.
Well, it is appropriate that my confusing question would generate
a confusing answer.
...but you got the gist of what I wanted to know. This is very new
to me, but the lights move as one, with one light moving up while the
other is moving down. How does one configure that unit to set the
range of motion? (I am afraid that you did answer this ;0)
Say that the position of one light all the way down and the other all
the way up is "zero". Then the program would be for the light to move
a specific distance, and then to move the same distance in the reverse.
This will return you to zero. In this instance, what sets how far the system
travels before it turns around?
...or does it just move in one direction, with some physical "flip"?
I suppose that I will need to figure out what you meant above...
"2in ball casters" == the "sleds that slide along the rail"
HZ == ?? Horizontal, usually.
I will Google it up. No worries.
