Sermoon D1 filament guide options see instructions

thingiverse

There are parts for several ways to guide the filament from the filament run out sensor to the hot end. option 1 Sermoon D1 guide .stl , this gives a reduction in friction as the filament gets on top of the frame. option 2 sermoon d1 guide .stl and the sermoon d1 extruder .stl, this involves drilling an 5/32" of 3.9mm hole 6mm down into the extruder arm. option 3 just use the support arm, drill the 6mm hole and run ptfe from extruder arm to anchor at the corner guide with end above the filament run out sensor option 4 Run a length of ptfe from extruder at max travel position to the run out sensor, then secure with end 60mm above sensor so filament can feed thru to the hot end. Possibly using zip ties to secure to the provided filament guide wheel frame. You do not have to drill the extruder arm for this, but it must be secure at the sensor end. The Sermoon D1 Gcode is an pre sliced program with the support arm , the extruder, and the pin and wheels to make the 3d printed parts for option 1 and option 3, with 2 wheel types, one that is usable immediately, and wheels that accept a 608 skateboard bearing to even more reduce the rolling resistance of the guides. 608 wheel bearing fitment, if you are having trouble with the bearing fitting into the wheel, usually causing the wheel to split. Grab the individual .stl, and either use the XY scaling to make it slightly larger in the slicer. Note no Z scaling or it wont fit into the arm mount. Also you can lower the extrusion multiplier to try to effect the hole being larger.
