# What you need
- 2 x PT100 Amplifier circuits. Typhoon™ is using 2 PT100 for temperature sensing and you need a PT100 amplifier board to make them work with your printer controller board. Any amplifier circuit will work, as PT100 is pretty standard. We do however recommend using our own amplifier board available on our online store (opens new window).
- Liquid-Cooling system (if you're not using Dyze Design Liquid Cooling Kit). You can find the minimum specs in our liquid cooling (opens new window) section.
WARNING
The Typhoon™ was designed to be actively cooled by a water loop. If you try to use it without a liquid cooling loop, you will experience issues.
# Mounting
Mounting the Typhoon can be done from 3 faces; Left, Right, and Back. Each one have two possible ways for the screws; either through holes or tapped holes. Depending on your mounting plate, one solution might be easier to access. Each face has two dowels holes for accurate positioning.
- Threaded holes are M4x0.70 and thread engagement should be 7.00mm.
- Dowels Pins holes are 4.00mm x 6.00mm depth
Check out our drawing page to get the 3D STEP file. Design your bracket according to the available mounting options.
On the CAD file, consider the following references:
- 3.30mm holes are M4.00 x 0.70 threaded holes
- 4.00mm holes are reamed holes for dowels pins
- 4.50mm holes are clearance for M4 screws
# Wiring
The Typhoon comes with a cable harness that is designed to connect from the HeatCore up to your electric box. The standard length is 2 meters. A diagram is show below with more information about the electrical connections.
# Heaters
Each heater has its own SSR. Two SSR can be provided with the Typhoon.
The fuse is optional but strongly suggested. Each fuse should be rated according to the power rating:
- Top heater, 250 Watts, 2.5A for 120VAC and 1.25A for 240VAC systems
- Bottom heater, 150 Watts, 1.5A for 120VAC and 0.75A for 240VAC systems
Many pins can be used as the temperature output control. Your 3D Printer Controller (or motion controller) pins can be as below:
- The standard extruder output (E0, E1, E2, etc). These are usually rated at the same voltage as your main power supply (12VDC or 24VDC).
- Any available expansion pins. These can be determined by checking the 3D Printer Controller specification pins.
Please refer to the following diagram for wiring the Typhoon:
# Backplate Add-On Connectors
The Typhoon has two extra connectors at its back. One is for fans, the other is for the Z probe (bed sensor).
# Fan connector
The fan connector mates with a Molex Mini-Fit Jr. The mating housing part number is 469920210.
Pin 1 | Pin 2 |

# Stepper Driver
# Using your own stepper driver
It’s possible to use your own stepper driver. However, make sure it can drive the motor with the specifications below, especially the current. We won’t be able to offer adequate support if an insufficient stepper driver is used.
# Using the Digital Stepper Motor Driver
Connect the PULSE (STEP), DIR, and ENA between your motion controller and the stepper driver. Please refer to your motion controller manufacturer datasheet for proper connections and pin locations.
WARNING
Do not connect the power output from a stepper driver into the signal input from our provided stepper driver.
ENA is optional. Stepper will be always active when open.
Apply power through V+ and V- according to the stepper driver specifications. Stepper windings should be connected to A+, A-, B+, B-. Colors are usually as follows: Black, Green, Red, Blue.
Check the micro-stepping and current configuration. Current should be set at 2.7A RMS and stepping should be set at 3200 pulses/revolutions (Equivalent to 16 micro-steps).

# Liquid cooling
The Typhoon is actively cooled by a water loop. Cooled parts are made from aluminum alloy, thus an aluminum radiator is required to prevent galvanic corrosion. Please check our liquid cooling (opens new window) section for more details.
# Part cooling
For part cooling, you can either design your own fan duct or you can take advantage of the integrated cooling shroud near the nozzle tip.
Each hole is about 3.2mm diameter.
# How to use
The cooling shroud is intended to work with compressed air. You can plug the air compressor tubing in the Pneumatic Push-In fitting at the back of the heatcore.
A 20-30 PSI air compressor should be enough to cool your printed parts.
# Using the cooling shroud with your printer board
If you want your 3d printer board to control the air supply, you will have to use a solenoid valve with a power mosfet and plug the relay signal in the FAN input of your 3d printer controller board.
Please refer to the following diagram for connecting the cooling shroud:
# 3D Printer Guideline
The Typhoon has a strong titanium heat barrier. However, this part is still the weak point of the melting zone and can be broken under certain circumstances. Make sure to follow these guidelines to prevent any damage to your Typhoon.
# General
Printing without cooling is only possible with large parts. Thick and large layers take time to cool down, thus requiring you to reduce speed for small parts.
Z homing must be done very carefully due to thermal expansion. For bed leveling with a cold extruder, make sure you compensate the thermal expansion:
- 0.25mm @ 200°C
- 0.41mm @ 300°C
- 0.56mm @ 400°C
Typhoon is designed and tested for 2.85mm filament. Never use “real” 3.00mm filament.
# Use Z lift
Raising the Z axis between each fast-travel is required. It will prevent any collision with the printed part. See the Slicer section for more info.
# Consider thermal expansion
It’s critical to consider the heat cylinder thermal expansion when doing the bed leveling. For example, if leveling at room temperature, the printing head will be 0.25mm lower. See the General topic to learn more.
# Maximum Axis Force
Make sure your axis isn't overpowered. Steppers don’t give feedback on their torque and an overpowered axis could easily damage the Typhoon.The Typhoon can resist a force of 50N at the tip of the nozzle.
# Non-Planar Typhoon™
The guidelines described in this document regarding the Typhoon™ also apply to the Non-Planar Typhoon™. There is no extra wiring, electronics or mounting to do.
Refer to the drawings and table below for an overall comparison between the Typhoon™ and Non-Planar Typhoon™.
Typhoon™ | Non-Planar Typhoon™ | |
---|---|---|
Maximum recommended nozzle temperature | 500 °C | 400 °C |
Overall length | 222 mm | 237mm |
Part cooling | ✅ | ❌ |
Minimal inclination angle (refer to drawings below) | 8 ° | 45 ° |
WARNING
Hot nozzle. Beware, contact may cause burns.
# Robotic Arm Guideline
If you plan on installing the Typhoon on a robotic Arm, you'll need to get some extra hardware to get the same features as a 3D printer controller. These items are the following:
- A motion planner capable of outputting STEP / DIR pulses for the stepper driver.
- Two (2) PT100 temperature sensor inputs.
- Two (2) digital output to drive the SSRs.

# Slicer and Print Settings
Set vertical lift to at least your layer thickness. For layers of 1.00mm, lift 1.00mm. Slicers aren’t yet optimized for large prints. Many over-extruded sections will be noticeable. Lifting the head will prevent any collision with the printed part.
Wipe nozzle to at least the line width. For a line width of 3.50mm, wipe 3.50mm or greater.
Set the heating to both heaters to the required temperature in the start Gcode script. Make sure to refer to your slicer documentation for variable names.
M109 T0 S[first_layer_temperature]
M109 T1 S[first_layer_temperature]
- Set end script to turn off both extruders:
M104 T0 S0 ; turn off extruder
M104 T1 S0 ; turn off extruder
Output flow and pressure greatly changed depending on the printing speed. To get the best result, keep the output flow steady by keeping the same speed everywhere.
Change the filament setting to 2.85 mm. Typhoon™’s step/mm was calculated using the area of a 2.85 mm filament. You will notice an exaggerated over extrusion with 1.75 mm filament in the slicer’s settings.
# Printing Speed
The tables below gives you the maximum volumetric flow for a specific polymer according to the nozzle size. If your polymer isn't there, please contact us (opens new window) and we'll do our best to add it to this list. We suggest using the Recommended volumetric flow as a starting point, but we also provided the Absolute maximum volumetric flow for reference.
Depending on your slicer configuration, a bit of math is required in order to find the right printing speed. The important parameters from your slicer are:
- Layer height
- Line width
For simplification, we won't consider the round edges for our speed calculation, but you can read more here (opens new window) if you are interested.
# Example Speed Calculation
Let's consider an example with the following parameters:
- Filament: ASA
- Typhoon nozzle: 2.50mm
- Layer height: 2.00mm
- Line width: 6.00mm
Considering the recommended table, ASA using a 2.50mm nozzle has a volumetric flow of 182 mm³/s.
The printing speed should be under 15.2 mm/s. It might seems slow, but remember that it is still 182 mm³/s, which is close to 1kg / h.

# Maintenance & Troubleshooting
# Clogged Nozzle
WARNING
Never drill any parts from the Typhoon. Some parts are hardened, others have a specific surface roughness. The drill could damage or get broken and stuck inside the unit.
# Causes
Clogging can be caused by a few factors. Make sure you understand which one is causing the issue and solve it before attempting a new print.
- Bad slicer settings
- Too high retraction. Make sure you are not pulling the molten filament too high. Try reducing it or disable it to see if the problem is solved.
- Too high volumetric flow. Make sure you aren't asking too much of the Typhoon. Thick and wide lines are misleading since a slow printing speed can still represent a high volumetric throughput.
- Bad filament conditions.
- Filament is not dry. A filament containing a lot of moisture will foam at the entry and greatly increase the friction. The print quality will also greatly suffer.
- Wrong temperatures. Usually, because of the very long melting zone, lower temperature can lead to better results.
- Bad filament quality. Always choose well rated polymers, and reliable brands. Paying a little more can save you a lot of trouble.
- Bad extruder and heatbreak cooling.
- Water is not flowing. Make sure the water is flowing properly. Validate my probing the extruder body temperature.
- Water is too hot. Think about changing the radiator or the fan for a bigger one.
# Solution
- Temporary extrude hotter
- Raise the temperature by steps of 10°C.
- Wait until the setpoint is reached.
- Send a slow extrusion command such as the one below. Please note that trying to push the filament by hand is worthless. The extruder has much more force.
G0 F60 E25
- Repeat until the extruder is unclogged or the temperature is too high.
- Visually inspect the system
- Set the target temperature to 0°C and wait until the unit has cooled.
- Loosen the filament lever.
- Remove the HeatCore. Slowly bring it down to see the filament.
- Observe the filament. Is there a larger, deformed section close to the threaded part of the HeatCore? Is there grinding marks from the driving section?
- If the filament looks undamaged and consistent in diameter, cut it flush to the heatbreak. However, if the filament looks larger and flattened, use a heatgun and point it towards the threads of the HeatCore. Slowly pull the filament out of the heatbreak.
# Gears
The gears can be accessed by removing two screws on the top. You should use those holes to grease the gears.
Remove the filament while greasing the gears and let the motor run freely while gently applying grease.
We suggest using white lithium grease. The Typhoon comes pre-greased with white lithium grease, ISO Viscosity Grade of 150.
We suggest using a small sized grease gun such as the Astro Mini Grease Gun (opens new window).
