This is a flange to mount a BMG Extruder to a FABtotum printer. It is intended to be mounted in the back panel of the FABtotum. The corrosponding hole pattern on the panel has to be shifted. I haven't done this. That's why I made a provisoric mount with duct tape.

One of the connectors extruder or printer has to be inverted. Without the stepper turns in the wrong direction. Means that you have to change the cable positions as shown below.
S---P | S---P (Stepper --- Printer connector)
1---1 => 4---1
2---2 => 3---2
3---3 => 2---3
4---4 => 1---4
Don't forget to recalibrate the steps for the extruder!
