# What you need

  • RTD-to-Digital Converter (i.e. MAX31865). Typhoon™ is using PT100 for temperature sensing and you need an amplifier board (like MAX31865) to make them work with your printer controller board.
  • Liquid-Cooling system (if you're not using Dyze Design Liquid Cooling Kit). You can find the minimum specs in our liquid cooling section.


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

Typhoon Mounting Example

# Wiring

# 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: Typhoon Electrical Connections and Wiring

# 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).

# 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.


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 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 section for more details.

# Part cooling

Typhoon 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.

Typhoon's integrated cooling shroud drawing

# 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.

Typhoon's Pneumatic Push-In fitting for compressed air

# 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:

Typhoon's integrated cooling shroud schematic

# 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.

# 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

  • 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.

  • 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.

# Maintenance

# Gears

The gears can be accessed by removing two screws on the top. You should use those holes to grease the gears.

Removing screws on the top of Typhoon extruder

Applying grease in the Typhoon extruder

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.
