OK been thinking about this all day.
Checked when I got home, absolutely know way to get the motor mount around the Prusa assembly:-(
So time to do a little design work.
I have include the A redesign of Ryans XCarriage
I have modified it to have the receiver holes need to connect the Prusa Extruder in the same orientation as the I3 MK3
print is going as I type.
I will send pictures Thursday:-)
See Ya
