In case this is helpful to some one else.
Here is a picture I put together for myself, of my setup.
I set my A Axis in the motor home soft limits to reverse.
Reason is the brass gear that the stepper motor turns that feeds the PLA,
must go in the direction to feed the PLA into the heated head.
Now the work begins of building 3D GCODE of something sinmple.
If some on has something small they can share that would be great.
Then I can see how good this system performs.
