M906 X800 Y800 Z800 E800 I50 set motor currents (mA) and motor idle factor in per cent Thermistor / Heaters I found that setting it to a lower current of E800 was satisfactory. In order to provide the Hemera motor with the correct amount of current, so as to have it’s ideal torque level, and not over heat, it is required to make some adjustments to the VREF on your stepper drivers.Į3D recommends setting the motor current to around E980 (mA). The standard Hemera motor has a rated motor current of 1.33A. I found that I needed to tweak that 409 value to E392.70 for more precise extrusion M92 X80.00 Y80.00 Z800.00 E392.70 set steps per mm Motor Current

For a x16 microstepping setting E3D recommends you start with a value of 409.

This number is used to make that conversion Your printer takes those lengths of filament and calculates how much it should rotate the Hemera stepper motor to push out the expected amount filament.

Your slicer will generate G-Code for your printer, which will tell it to extrude a certain length (in millimeters) of filament.

The wiring detailed in my PDF ensures all the motors turn in the same direction.

Chris does a great job of breaking down all of the configuration file changes.Īfter wiring the Hemera you will need to update some parameters in the Duet’s config.g file per the E3D reprap directions. Recently a youtuber “Chris’ Basement” put out a video of installing the Hemera on an Ender 3 with a Duet mainboard. I recommend adding quick disconnects to both Fans to make them easier to change out in the event of a failure. I will link to a PDF to show the wiring and connector orientation used. I used Cat6 Ethernet cable for the Extruder and X-axis. I installed both the Hemera and the Duet 2 at the same time as updating the wiring. Make sure you get the right fan and Hemera (24VDC).

During this install keep in mind that the Ender 5 Pro power supply is 24VDC and NOT 12VDC.

For some guidance I recommend watching this video from 3D Printing Canada using Although the video shows an Ender 5 PLUS model which is not an exact match for the Ender 5 Pro it was very useful to help me understand the entire process. Now that you have printed your mount you can safely start removing the stock direct drive motor from the frame of the Ender 5. Hemera with Metal BL Touch Mount Removing the current hot end and drive system

I recommend you print a few options before disassembling your current printer.Īs part of the mount I also printed a part cooling duct for an aftermarket fan: Since my install a few more mounts have popped up. However, I still had the metal BL-Touch bracket that came with the Ender 5 BL Touch kit which with some slight modification to the printed mount proved to be a far better solution. I used this mount but I found the BL Touch portion of the bracket to be very flimsy and it broke off during the install. To select your mount I recommend visiting and searching for “Ender 5 Hemera BL Touch”. So I printed the mount in PLA and so far it has been rock solid. With the stock printer I had issues with printing in anything other than PLA.

Ideally you print in something durable like PETG or ABS.

Hemera on my Ender 5 with BL Touch Hemera Installīefore you start taking your printer apart you need to print a new mount for the Hemera.

Wider range of temperature ability at the hot end which was a combination of the Duet driving the Hemera.

Better part cooling performance with quieter 24VDC fans.

Print with a wider rage of materials such as the ninja flex.

However, I found by moving to the Hemera direct drive solution it is light weight enough that I retained the same speed I was getting out of the stock Ender 5 and improved the following:

The stock Bowden setup can have speed advantages because you have less weight on the moving parts and thus less inertia to overcome when the extruder needs to rapidly change directions.
