Pika for Bambu X1 Series Assembly Instructions

Everything Separate from Pika hotend parts you will need for Pika Hotend Assembly:

Thermal Grease
Thermal Grease Applicator
6mm Hex Nozzle Wrench
Hotend Fan
T8 Torx Driver
Clamp
Torque Wrench

Pika Hotend parts you will need for assembly:

Pika Heatsink
2x Pika Wings
2x T8 Fan Screws
Pika Silicone Sock
Pika Heatbreak
Pika Silicone Sock
Retention Clip
Pika Heatblock
x4 T8 wing screws
Heater
Thermistor
FIN Nozzle

Step 1:

You will need:

Heatbreak
Heatblock
Torque Wrench
Clamp/tool for holding block in place while torquing.

1a:

Take your Heatbreak, and insert it into the side of the Heatblock that does not have the foot.

1b:

Begin turning the Heatbreak into the threads. Keep turning until you can't.

*If it is not easy to turn with your fingers, that is okay. The torque wrench will take care of it later!

The image above is how your assembly should look before torquing.

1c:

Use a clamp to hold your block assembly in place. We use 3d printed fixturing.

Use your torque wrench to tighten the heatbreak to 3Nm. If your heatbreak was not easy to finger tighten, you will need to use the torque wrench to turn the break a few times before the numbers start reading correctly.

Step 2:

You will need:

T8 Torx Driver
Heatblock Assembly
Two Pika Wings
2x T8 Torx Screws

2a:

Take one of the T8 Torx screws shown above.

Insert it through one of the wing holes, as shown below.

2b:

Affix the wing to the side of the heatblock that has the Thermistor Hole.

Make sure that the shortest side of the wing is on the side with the Thermistor Hole.

The flat side of the wing needs to be pointing towards the heatbreak.

2c:

Flip the Pika Heatblock Assembly over, and affix the second wing using the T8 Torx screw.

It is easiest to insert the screw through the wing hole, and then set both on top of the Heatblock hole.

Make sure your wings are aligned facing the same direction.

Step 3:

For this step, you will need the following:

Heatblock Assembly
Thermal Grease
Retention Clip
Heater
Thermistor
T8 Torx Driver

3a:

Thread the thermistor wire through the wing on the Thermistor Hole side.

3b:

Loosen the wing on the Thermistor Hole side of the heatblock, so you can tip the wing down towards the Foot.

Now that there is enough space, you can thread the heating element side of the heater through the widest part of the wing.

Realign the wing, and tighten the torx screw enough that the wing isn't wiggly for the next steps.

3c:

Take your Thermal Grease. If your thermal grease is in a tube, you may be able to squirt it directly into the Thermistor Hole.

If not, you can apply it directly to the tip of your thermistor. Make sure the grease is covering the entire "bead" at the end of your thermistor.

3d:

Next, insert the bead of your thermistor into the Thermistor Hole. Make sure to fully insert the thermistor, or your hotend temperature readings will not be accurate.

3e:

Gently grab the connector end of the thermistor, and pull the thermistor through the short side of the wing.

Make sure not to allow the wires to snag on the wing while you are pulling.

Take care not to remove the thermistor from the hole.

Your Pika Hotend Assembly should now look like this:

3f:

For the next part of the step, we will be installing the heater. Make sure the heater is going through the wing properly before continuing.

Once you are sure, apply the Thermal Grease generously to the flat portion of the heatblock on the foot side like so:

3g:

Shorten the amount of wire on the greased side of the heatblock. Press the flat side of your heater against the heatblock, making sure the heater butts up to the foot.

3h:

Take your retaining clip, and slide it over the flat of your heater. Make sure the orientation of the retention clip matches the image below.

If you are having difficulty with sliding the clip, you can use the table to more easily press it onto the heatblock.

When it is in the proper position, your Pika Hotend assembly will look like this:

Step 4:

For this step, you will need the following:

Thermal Grease
Applicator
Heatblock Assembly

4a:

Use your applicator to apply thermal grease to the outside of your heatbreak. See the image below to determine which portion of the heatbreak should receive grease.

Make sure not to get grease inside of your heatbreak. That could cause clogging within your hotend. If you do get grease inside the heatbreak, remove it carefully, to avoid scratching the heat treatment off your heatbreak.

Step 5:

For this step, you will need the following:

Pika Heatsink
Pika Heatblock Assembly

Step 5a:

Insert the heatblock assembly into the heatsink.

Make sure your heater and thermistor are on the side that has a wiring channel.

5b:

Once the wing is lined up with the heatsink slot, loosen the screw on the heater side of the block.

If the wing on the other side is preventing you from pushing the heatblock assembly further into the heatsink, you can loosen the screw on that side as well.

Step 5c:

Route the heater and thermistor through the heatsink channel.

Line up the wings so the holes are centered with the heatsink holes.

Step 6:

For this step, you will need the following:

Pika Heatblock Assembly
2x T8 torx screws
T8 Torx Driver

Loosen the screw that is attaching the wing to the heatblock.

Install the first new screw, but do not fully tighten it yet.

Install the third screw. If you are having trouble getting the last holes aligned, you can try loosening the other two screws more. You can also press that side of the wing in whichever direction is helpful while installing.

Once all three screws are in, you can fully tighten them!

Step 7: Fan installation

For this step, you will need the following:

Pika Hotend Assembly
Hotend Fan
2x Fan Screws
T8 Torx Driver

Step 7a: Wing Alignment

Make sure the wing on the fan side is properly aligned. You should loosen the screw on that side if it is tight. Press on the wing until it seems aligned with the heatsink.
