Introduction

Purchase your Hemera here: https://e3d-online.com/e3d-hemera-175-ki...

For the printed parts please see:

https://www.thingiverse.com/thing:400939...

for Bl touch users please see:

https://www.myminifactory.com/object/3d-...

Please note that this guide is assuming the use of a fully assembled and hot tightened Hemera unit if you have not yet fully assembled and hot tightened your unit please see: Hemera Assembly Guides

Mounting a Hemera to a Creality Ender 3 is easy, and we provide most of the tools you'll need. Please note, though, that you should be very careful of the following safety cautions:

  • Be aware of your electronics. Don't work on your printer while it is plugged in or turned on.
  • Be aware when you heat up your new hotend not to burn yourself on the heater block nozzle or heater cartridge.
  • The standard Hemera is capable of printing up to 285°C, do not exceed these temperatures unless you have replaced the Thermistor cartridge with a PT100, the Aluminium heater block with a Plated copper heater block, and the Brass nozzle for a Plated copper, Hardened steel or Nozzle X.
  • Firmware modification is not optional it is a mandatory step,
  • Make sure you have ordered and received the correct voltage heater and fan to match the power supply of your printer. All of our current heater cartridges should have the voltage and wattage laser engraved on the cartridge. Taking an ohm reading is the most reliable method of testing what voltage/ wattage you have received.
  • Connecting 12v parts to a 24v power supply can result in overheating, component damage, or fire. If you are unsure double check the rating on your power supply.
  • Your HotEnd and your printer are your responsibility. We cannot be held responsible for damages caused by the use, misuse or abuse of our products.
  • We provide these guides as a reference to show that it is possible to mount a Hemera to a Creality Ender 3. Users should be mindful that your specific use case may vary and further modifications or additions may be required.

    • Raise the X gantry to roughly the middle of the Z axis to allow you to have good access.

    • Make sure you have unloaded the filament from the Ender 3.

    • Make sure the hotend has been allowed to cool to room temperature before beginning any modifications.

    • Make sure you turn off and unplug the printer before making any modifications.

I’m trying to put my Hemera on my CR-10S and the stepper cable provided with my Hemera is pinned differently than the cables that came with my CR-10S Yours [XOXXXO] CR-10S steppers are wired [XOXXOX] where the X is a live pin and and O is non wired pin in the plug. I don’t want to burn out my board.

Hi , you can use the stock cable

Yves lefebvre -

the same obstacle here (cr-10S)

the stock cable is a lot shorter I would like to solder the hermes supplied cable with the existing one.

Hi Tony,

If the stepper motor cable is causing issues you can switch the middle two wires in the connector.
