Fitting the soft polymer feeding unit (SPFU)
Used when soft filaments are needed (that are really difficult to use with standard feeders), the SFPU feeder
lets you use any elastic filament available for FDM/FFF printers.
Here follows the mounting procedure:
1. remove filaments from all extruders, remove machine
cover
2. turn off machine and follow procedure to remove PTFE
piping from extruders
3. unplug the #1 feeder: be sure to pull the connector NOT
the cable !
4. Route the feeder cable thru PTFE passage on machine
rear side and bring it toward extruder assembly
5. Wrap the feeder cable around the black piping going
from machine body to extruder assy
