Sharing my Extruder installation.
Hope it will helps others who are considering to install Hemera extruder.
Extruder out of the box
Installation process begins
Installing Hotend - Heat block and Nozzle
Mounting the extruder on teh XY carrige
Wiring the extruder to Duet board
Finally, all set

As requested, here is an update, with the new config file, to match RepRap Firmware V3.0
Note: I completely removed the Z-axis endstop, and I am using Stall detection to home the Z axis.

I was able to do the same conversion on my newer FFCP. Installed the Hemera and Duet Wifi and your configs worked very well. I ended up adding a BLTouch as well which has made homing the Z-axis more accurate plus adds all the benefits of bed levelling and mesh.
I remixed your Hemera mount to add a mount for the BLTouch and a 5cm post to tie the wiring to. Seems to work very well. I’ll post the remix on Thingiverse.
Thanks so much for your efforts. Much appreciated!

@Zebble any chance you can link to your remix? I'm getting ready to add a Hemera to my FFCP, and I'd like the option of BLtouch.

I wonder how feasible it would be to do a dual extruder version of this conversion. Is there a mirrored version of the Hemera?
