Hello Experts,

I am a newbie here. I am having a weird problem for which I can not figure out a solution. While printing it randomly skips a line or two (see attached photo). I have an Ender 3 Pro that is about a month old. I have installed a glass bed on it and I am using silk white pla. I am printing with the following settings: 210 C Nozzle temperature, Bed at 60 C, Fan speed at 70%, Print speed at 45 mm/s, layer height 0.2 mm with stock nozzle, 10% cubic infill, and plate adhesion type is skirt. Any help/advise would be appreciated. Thanks

Nozzle temperature for PLA 195-200 is good enough. Try to reduce the temp first and see if it getting better. 

What filament you are using. Uneven filament could be one reason. try a different brand PLA.

the last issue would be the extruder motor. pay attention to the extruder gears when it’s printing. Check if the motor moves or not when the missed line starts to appear.
