Mount the Flexion extruder to the Printrbot Simple Metal with these adapters.
*These adapters are for the E3D version of the Flexion extruder.
*You must have the longer E3D Volcano or it may not reach the print bed.
*You must have a 1/4" mic6 aluminum print bed upgrade or the hot-end may not reach the bed.
UPDATE: Front Clip v6 has tighter tolerances and clamps tighter, but may be more difficult to install.
The threaded holes may not print well with larger layer heights.
Print the adapters and make sure the threaded holes will accept M3 bolts. The front clip requires two 16mm bolts minimum. The rear clip can be used with 6mm minimum up to 12mm max length.
Raise the printer in Z to allow room to work on the extruder. TURN OFF THE PRINTER. Unbolt and remove the hot-end and extruder assembly and put aside. Unbolting the Y arm (6 bolts) will make the next steps easier, so unplug the cooling fan and Z sensor (note orientation: red to black).
Mount the the Flexion upper assembly to the extruder motor. Get the mounting hardware knolled out and ready. Insert the E3D up through the extruder hole in the Y arm, then slide the Flexion E3D mounting block around the hot-end. Install the cover plate with two bolts into the extruder motor. Attach the rear clip first, then attach the front clip to secure the extruder to the Y arm.
