#Hemera disassembly update

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. When you pop off the faceplate the filament, idler and spring all come along too, as one neat assembly.Direct vs Bowden extrusion.

Full access is available to clean and replace parts even while filament is loaded. Should you need to disassemble Hemera for maintenance, the internal mechanisms are easily accessible by removing the fan, and undoing the two faceplate screws. Filament tension is increased by rotating clockwise and decreased by rotating counterclockwise. To set filament tension the user simply twists a thumbscrew and a cam slider mechanism with a captive nut compresses a spring and loads the idler. User-centered DesignĪll interaction with Hemera is from the top.

Hemera’ heatsink design ensures airflow is diverted up and away from both the HotEnd and the heated bed, reducing the risk of warping and uneven stresses forming in the printed part. Hemera features convenient T-Slots for easy mounting to your printer, plus space for other accessories, part cooling fans and bed levelling probes to name a couple. This exceptional filament constraint also has a significant impact on printing rigid, and semi-rigid materials such as PLA or Nylon.

You won’t experience the full extent of its unrivalled filament constraint until you print ultra-flexible materials. Hemera constrains filament like no other extrusion system, fact. It has a custom motor which is based on a NEMA17, along with our own faceplate designs which has allowed us to add our own features for user convenience, such as mounting slots as well as produce a very compact system. Hemera is a system of components designed to work seamlessly together as a single compact product.

The secondary gear shaft is on a moveable, sprung idler which allows the user to adjust filament tension. For E3D Hemera, we opted for a hardened stainless steel dual-drive arrangement which provides a huge boost in grip over single drive systems, in fact, we’re able to push filament with up to 10kg of force.
