Installing the Asteroid Tool Head

Task 1: Remove the current tool head

Tools & Supplies Needed:

Micro cutters
2.5mm Hex key

Instructions:

Allow it to cool down before removing.

It may be helpful to lower the tool head.

Click Menu → Move Axis → Filament or Tool Head Swap

1.1 Remove filament from current tool head by cutting the filament leaving a ~3” tail.

1.2 Turn the printer off by flipping the red switch.

1.3 Remove the Proto Cover from the tool head by unscrewing the the top center screw indicated in the below picture.

Tape screw to the Proto cover & store in the tool tray inside the drawer.

1.4 Unplug the black wire connector.

Press the little lever down (on left side) and gently pull apart.

1.5 Securely hold the tool head with one hand while unscrewing the two top screws and the one long screw in the back of the tool head.

Keep the two top screws. They will be needed for Task 2.

1.6 For safe keeping, screw the long screw into the back of the HS+ tool head and set aside for now.

Task 2: Install the Asteroid Tool Head

Tools & Supplies Needed:

Asteroid Tool Head w/ attached BLTouch Sensor
2.5mm hex key
2 small screws from task 2 (that were on top of tool head)
1 Long thumbscrew (for the back of tool head)

Instructions:

Before you begin notes:

Do NOT set the Asteroid Tool Head on the Magnetic bed as this may damage the BLTouch sensor.

You may set the tool head next to the printer inside the kiosk.

2.1 Align the circular grooves on the Asteroid Tool Head with the mount on printer.

2.2 Hold the tool head in place with one hand. Then, screw in the long back thumb screw FIRST, followed by the top two screws.

2.3 Fully tighten the top two screws with a 2.5mm hex key.

2.4 Plug in the BLTouch connectors (If you already had a BL Touch, feel free to skip this step)

Need to do these first b/c wires are short and must go under the tool head wires.

2.5 Plug in the black tool head connectors together (the one with the silver sticker on the back and bundle of wires)

2.6 Turn on the printer and verify that BLTouch light is solid red.

You will see that BLTouch will be lit solid red (indicating it is working properly) and the probe will extend and retract twice when the printer is first turned on.

Woohoo!!! You have successfully installed the Asteroid Tool Head!

If the red light on the BLTouch is blinking, then there is an error with the BLTouch sensor.

Try this: Turn off printer. Verify that all connectors are fully plugged in. Turn printer back on. Is the red light still blinking? No → it is working properly and you may move onto Task 3.Yes → the tool head will need to be sent back to us and we will send a new one asap.

Followup on the support ticket with the installation update and we'll send you a return label.
