I’ve just switched to E3D v6 hotend and bowden setup on wanhao duplicator i3+.
ADVi3++ version 4.0.5
I’m having 2 problems with the extruder motor:
- It makes this loud buzzing noise which it didn’t before (https://drive.google.com/open?id=1-XYKDpoFHoJkT5S0hymzKSZ5U4M7qO-Z).
- Somewhere in the middle of the print it usually grinds on the filament and thus stops extruding.
I’ve calibrated E-steps in the software. Tried lowering the extrusion rate (gcode), prints get under-extruded, but this noise still persists.
Any help appreciated,
thanks in advance
