Your extruder

Make sure you have the right DyzeXtruder

The name and version can be confusing. Make sure yours looks like the one below:

DyzeXtruder GT
DyzeXtruder GT
DyzeXtruder Pro High Performance Extruder
DyzeXtruder Pro

Step 1: Electronics

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 has this feature. Refer to the main board section if you aren’t sure. The values for firmware controlled current are detailed in step 2.

  1. Adjust the current limiter on your stepper drivers.

How can I find my Rs resistance value?

How can I determine my stepper driver?

  1. 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.

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.

The DyzeXtruder GT requires less than 0.9 ampere to work.

Plug the motor

 

Refer to your main board for proper extruder installation.

Ensure to use the cable provided with your extruder. Not all cables and motor have the same pinout.

If the motor is turning in the wrong direction, change the direction in the firmware directly or change the orientation of the motor.

Step 2: Firmware

Insert the appropriate value from the above table depending on your stepper driver.

The steps/mm provided are theoretical values to be used as a starting point. Steps/mm might need to be changed according to the printer extrusion flow and configurations. We recommend doing a calibration after the first installation. You should take these new values as your “default steps per unit” in the firmware.

Please note Redeem consider full steps for its configuration. If you have a 250 steps / mm at 16 µsteps, your value is 250 / 16 = 15.625

steps_pr_mm_e = XXX

Step 3: Cooling

 

It is preferable to install a fan over the heatsink to help to cool the stepper driver. The high current set-up requires active cooling of 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

Step 6: Install the DyzeXtruder

Use an existing bracket

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

Design your own bracket

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

Step 7: Use the DyzeXtruder

Insert a filament

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.

Insert the filament.

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

Remove a filament

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.

Remove the filament.

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

Install a HotEnd

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.

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


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

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

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.
Measure example

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.

    Theres no instruction for connection the heater, specifically polarity.

    Theres no instructions for connecting the PT100 sensor.
