When I am trying to print something on my home made 3D printer, I can print the first and second layer, then the Bowden extruder's gear starts slipping; it cannot push the filament anymore,the gear is turning but slipping; the filament cannot go forward.
I tried all configurations of the tightening screw of the spring, corrected PID settings, cleaned the nozzle, tried with 200 °C up to 215 °C (I am using PLA) but no result.
I am wondering whether this is related to speed, feedrate and acceleration settings. The Slic3r puts automatically a feedrate as F1800, is this too high ? Do I have to change it every time I slice something? I might proceed with trial and error method but I need a more rational method.
The slicer I use (Slic3r) puts F1800 as speed. Is this too high ? Could this be a reason for the filament to slip ?
My filament's diameter is 1.75 mm. In the G-code file created by my slicer (Slic3r), the flows are shown as follows:
; external perimeters extrusion width = 0.44mm (4.25mm^3/s) ; perimeters extrusion width = 0.42mm (8.02mm^3/s) ; infill extrusion width = 0.42mm (10.69mm^3/s) ; solid infill extrusion width = 0.42mm (2.67mm^3/s) ; top infill extrusion width = 0.42mm (2.00mm^3/s) ; support material extrusion width = 0.44mm (8.50mm^3/s)
