Hi all,I am using an Anet A8 since a long time and it has been working great. When i started a print yesterday i noticed that there were no filament coming out of the nozzle. After checking i noticed that the extrusion motor i "slipping" when trying to extrude. Now i have changed most of the parts including the motor itself, nozzle, tube, filament type, heating block, etc. Still the same problem!Video of the problem:https://1drv.ms/v/s!Ajy2UcKN8hXUxjIqU6IjpZDbrddLIf i ease the pressure on the filament drive cog wheel it will extrude but then slip on the filament itself due to no pressure. Also if i manually press filament into the heating block it can be done with ease, so no blocking.Can anyone give me suggestions on this? Could it be the current to the motor? Please help, im lost!
