Oh, I meant that the effects of 'tooltip' and 'work' only become visible if you have a connection from linuxcnc to the vismach model by connection the halpins you created in the vismach code like:
#create the HAL component and pins
comp = hal.component("vismach-example")
comp.newpin("joint0", hal.HAL_FLOAT, hal.HAL_IN)
comp.ready()
And use them to translate/rotate the body to which the 'tooltip' has been attached by the Collection() function. ie it will then draw the line that 'records' the movement.
