MK3S HEMERA FIRMWARE
I have done the hardware upgrade of my Prusa Mk3s and now I need the firmware. I am not sure where to look for the latest information and what exactly to change. There are several posts on the E3D website but they seem outdated and confused. Please help!
RE: MK3S HEMERA FIRMWARE
Not enough information. What update did you do that has you looking for firmware at a 3rd party site?

Sorry, I did the BearMera upgrade. All of the firmware changes were from the author, Grégoire Saunier
See this site for the firmware changes: 5. Software configuration - Bear Lab (bear-lab.com)
All the parts fit well and everything works except the extruder motor - it will not do any movement with either the load or unload command.
I have tried reversing the red and green wires on the extruder motor as some have suggested but this does not help.
There was a patch for the firmware see attached.

the website would not let me attach the gcode file - here it is printed.
