Note about using this guide

This guide is short and well structured. Make sure to follow each step. If you don't, you  may not be able to use these products correctly or even damage them. Some features can save you a lot of trouble if you know how to use them properly.

Step 1: Electronics

1.1 Plug the motor

Refer to your main board for proper extruder installation.

1.2 Adjust your current setting

Some boards can adjust motor current with the firmware. If you don't see any potentiometer, there is a high chance that your board have this feature. Refer to the main board section if you aren sure. The values for firmware controlled current are detailed in the step 2.
Adjust the current limiter on your stepper drivers. 

How can I adjust my stepper drivers?

How can I find my Rs resistance value?

How can I determine my stepper driver?

Adjust your stepper drivers to the values listed below.

If your motor is running hot, above 45°C, reduce the current by 10% until you reach a maximum of 45°C. 90% of the rated current is a good starting point.

Motor coils have a wide tolerance regarding resistance. Two identical extruders might require different stepper adjustments. Temperature is the easiest way to determine if the motor is running at the right current.

Step 3:Cooling

It is preferable to install a fan over the heatsink to help cooling the stepper driver.The high current set-up require active cooling to the stepper driver in order to maintain a low enough temperature.

Make sure the stepper driver has a heatsink installed with thermal paste or thermal adhesive. The heatsink should be positioned precisely and should not touch the contacts pins.

Step 4:Slicer

Configure your slicer with the following values listed below.

Find the according setting based on your Slicer

ExtruderSetting NameBase valueMaximum value
DyzeXtruderRetraction Speed30 mm/s ( 1800 mm/min )75 mm/s ( 4500 mm/min )
DyzeXtruder GTRetraction Speed25 mm/s ( 1500 mm/min )35 mm/s ( 2100 mm/min )

Step 5: Install the DyzeXtruder

Use an already existing bracket

Refer to the Preconfigured Printers section for brackets and mounting solutions.

Design your own bracket

Get the latest CAD here: Drawing

Please note that you only need to mount the bracket on one side of the DyzeXtruder.

Do not remove the 4 front screws to mount your DyzeXtruder.

Step 6: Use the DyzeXtruder

2. Follow each steps on the right. Click on each one to reveal a video and more details.

Insert a filament

1Insert filament
Push the lever closer to the brass push-fitting. While keeping it pushed, insert the filament. Rotating the filament can help it going through the extruder more easily.

1Lock the lever
Push the large lever closer to the push-fitting. Engage the locking mechanism and release the lever. The locking mechanism should hold the lever in place. 

2Insert filament

Insert the filament. 

3Release the lever

Push the lever once more, the locking mechanism will release itself. Gently release the lever.

Remove a filament

1Remove filament
Push the lever closer to the brass push-fitting. While keeping it pushed, remove the filament.

1Lock the lever
Push the lever closer to the push-fitting. Push the locking mechanism and release the lever. The locking mechanism should hold the lever in place. 

2Remove filament
Remove the filament.

3Release the lever
Push the lever once more, the locking mechanism will release itself. Gently release the lever.

Install a HotEnd

1Loosen the GrooveMount screws
Using a 2.5mm Allen, loosen the top button head cap screw by a few turns.

Using a 2mm Allen, loosen the bottom button head cap screw by a few turns too.

2Install the HotEnd
Using a 2.5mm Allen, slightly tighten the top button head cap screw until the GrooveMount plate toutches the HotEnd.

Using a 2mm Allen, tighten the bottom button head cap screw until it touches the GrooveMount plate.

Position the HotEnd.

Using a 2.5mm Allen, slightly tighten the top button head cap screw until the HotEnd is held in place.

1Loosen the GrooveMount screws
Using a 2mm Allen, loosen the top button head cap screw by a few turns.

Using a 2mm Allen, loosen the bottom button head cap screw by a few turns too.

2Adjust the groovemount to your hotend
Using a 2mm Allen, slightly tighten the bottom button head cap screw until the GrooveMount plate toutches the HotEnd. You should be able to remove it and install it easily.

Please note!

This step must only be done once. Using the same hotend won't require adjustments.

3Install the HotEnd
Using a 2mm Allen, tighten the bottom button head cap screw until it touches the GrooveMount plate.

Position the HotEnd to your required orientation.

Using a 2mm Allen, slightly tighten the top button head cap screw until the HotEnd is held in place.

Remove a HotEnd

1Loosen the top GrooveMount screw
Using a 2.5mm Allen, loosen the top button head cap screw by a few turns.

Turn the hotend GrooveMount holder and remove the hotend.

1Loosen the top GrooveMount screw
Using a 2mm Allen, loosen the top button head cap screw by a few turns.

Turn the hotend GrooveMount holder and remove the hotend.

Setup for Bowden

DyzEnd-X Bowden Setup Tube Length

Measure example

The DyzeXtruders product can work either way, either in direct drive using the groove mount system or by reversing the motor direction for Bowden setup.

  1. For the extruder alone, you need a length of 15mm, from the top.
  2. Add the height of your fitting.
  3. Mark the tubing to visualize the depth.
  4. Insert the tubing up to the mark. The filament must be well guided inside the hotend with this tubing.

Filament direction

Method 1: Switch the cable orientation

The 4 pin cable connected to your board can be connected in the opposite order by making an 180° rotation. This will reverse the motor direction as the coils order are reversed.

Method 2: Firmware modification

Firmware can reverse the extrusion direction. Find the corresponding option and reverse the logic.
