The File

Spring.FCStd

Script

Spring.FCMacro

import FreeCAD, FreeCADGui, Draft, Part
from FreeCAD import Base
import time

ii = iib = FreeCAD.getDocument("Spring").getObject("Helix001").Pitch
i = ib = FreeCAD.getDocument("Spring").getObject("Helix001").Height

pas = 1

for ii2 in range(int(60)):
    if pas == 0:
        if ii > iib-1:
            pas = 1
        else:
            ii += 1
            i = (ii * 10)
    else:
        if ii < 2:
            pas = 0
        else:
            ii -= 1
            i = (ii * 10)
   
    FreeCAD.getDocument("Spring").getObject("Helix001").Pitch = ii
    FreeCAD.getDocument("Spring").getObject("Helix001").Height = i
    App.Console.PrintMessage(str(ii2)+"  " + str(ii)+"  " + str(i)+"  " + str(pas) +"\n")
    Gui.updateGui()
    time.sleep(0.1) # modify the time here
#FreeCAD.getDocument("Spring").getObject("Helix001").Pitch = iib
#FreeCAD.getDocument("Spring").getObject("Helix001").Height = ib
