Dual drive extruder upgrade

If you want to upgrade your mini to a Dual drive extruder, you've got a few options
you can read it in full on All3DP

Please note two things:
1. you might need to change the electroincs wires
2. you need to add some changes to the PrusaSclier (currently the FW is buged and doesn't save changes)

On PrusaSlicer add to the Mini's Start G-code the following commands;

M109 S[first_layer_temperature] ; wait for extruder temp
M92 E415 ; Bondtech ESTEP change for extruder upgrade
