HHS doesn't show up in the visualizer

General

Hey everyone, I’ve setup two Hamilton Heater Shaker modules in PLR. I used the guide to setup two HHS modules connected directly to the STAR, however they don’t show up in the visualizer.

When I use the core grippers to move a plate to that location, I see that the plate is moved to the correct location. Lock and shake commands work (in simulation, haven’t tested in hardware yet).

Here’s my code:

interface_choice = "star_control" 

# HS1
hhsbackend1 = HamiltonHeaterShakerBackend()

hs1 = HeaterShaker(
  name="Hamilton HeaterShaker",
  backend=hhsbackend1,
  size_x=146.2,
  size_y=103.8,
  size_z=74.11,
  child_location=Coordinate(
     x=TUBE_CARRIER_3.get_absolute_location().x + TUBE_CARRIER_3._size_x + 5,
     y=455.5,
     z=183
  ),
)

hs1.location=Coordinate(
     x=TUBE_CARRIER_3.get_absolute_location().x + TUBE_CARRIER_3._size_x + 5,
     y=455.5,
     z=183
    ),

# HS2
hhsbackend2 = HamiltonHeaterShakerBackend()

hs2 = HeaterShaker(
  name="Hamilton HeaterShaker",
  backend=hhsbackend2,
  size_x=146.2,
  size_y=103.8,
  size_z=74.11,
  child_location=Coordinate(
     x=TUBE_CARRIER_3.get_absolute_location().x + TUBE_CARRIER_3._size_x + 5,
     y=455.5 - 103.8 - 5,
     z=183
  ),
)

hs2.location=Coordinate(
     x=TUBE_CARRIER_3.get_absolute_location().x + TUBE_CARRIER_3._size_x + 5,
     y=455.5 - 103.8 - 5,
     z=183
    ),

for hs in [hs1, hs2]:
  await hs.setup()

have you assigned these resources to the deck somehow?

I see that you’re setting the location, but in order to connect them to the resource tree you need to use assign_child_resource in some way.

e.g.

shaker_carrier = MFX_CAR_P3_SHAKER(
  name="shaker_carrier",
  modules={0: hs2, 1: hs1, 2: hs0}
)
lh.deck.assign_child_resource(shaker_carrier, rails=5)

That was it!

Would be nice to have in the Hello World, “Hamilton Heater Shaker”! guide, although I can see that having to assign the resource is obvious to seasoned PLR devs!

good feedback! (i always love it when new people come and give “first impressions feedback”! this window is too short :))
