I have decided to apply this to the worst performing printer first so I still have 2 working machines to aid in this effort. The aluminum plate looks good on my home made machine..

I have decided for the time to stay with the mk8 extruder at least until it is printing as good as the geeetech i3. So I have the monoprice mini printing out a simple mount that will attach to the nema17 stepper motor and hold the sensor..
