Why can't you stop a piston..

[harlequin_corps]

You can extend, you can retract, you can reverse.. you can't stop. Why?

Kill the power to it, it will stop. :)
You can also set the distance that you need it to stop at either at max or min value.

Hi, I don't know why but you may also use the "Reset Velocity" to 0 to stop it.

you know the speed. just turn it on/off with timers.

or if you are not short of space, use more pistons. extend one. extend the next, then the next:
bingo multi stage pistons. you can even zigzag and have some reversed so they pull to get longer.

I sometime use a script, a PB with run arguments, length and speed i can call from a button/timer/sensor.

Edit: located my move_piston function

use it something like this:

void move_piston(IMyPistonBase piston, float new_position, float speed)
{
new_position = Math.Abs(new_position);
speed = Math.Abs(speed);
Echo("Moving: " + piston.CustomName);
Echo("To Position:" + new_position.ToString());
Echo("Speed:" + speed.ToString());
if (piston.CurrentPosition > new_position)
{
piston.MaxLimit = piston.HighestPosition;
piston.MinLimit = Math.Max(new_position, piston.LowestPosition);
piston.Velocity = -speed;
}
else
{
piston.MaxLimit = Math.Min(new_position, piston.HighestPosition);
piston.MinLimit = piston.LowestPosition;
piston.Velocity = speed;
}
piston.CustomData = "Position = " + new_position.ToString("#,##0.00");
}

public void Main(string argument, UpdateType updateSource)
{
string[] x = argument.Split(',');
IMyPistonBase p = (IMyPistonBase)GridTerminalSystem.GetBlockWithName( x[0] );
move_piston( p, float.Parse(x[1]), float.Parse(x[2]) );
}

call the pb with arguments [piston name].[position],[speed]
e.g. Piston 1,0.5,2

If you need it to stop because you want it to open only half way, just set the maximum distance to 5.0 and then reverse it to make it extend.

[harlequin_corps]

or.. maybe.. Just thinking outside the box here, just throwing this out there.. run it up the flagpole and that.. have a button that says "stop" next to the buttons for "extend" and "retract".

[harlequin_corps]

For extra ribbed pleasure have a momentary "extend" and "retract" button.

Good pointers there. Pistons get locked pretty well and instantly when shut down. As for the min/max travel distance, once the piston head is within the range of the two, it will not leave. You can also, say, slowly increase the max distance while having the piston set to extend as an alternative method of finding how far you want it to go.

I usually use the maximum distance setting which will allow you to move it in small increments so you can back out of the control panel and look at it. GL

Found this very helpful. Thank you. :)
