Hello everyone, I'm new here so I don't really know if this is the correct place to put this issue but I'll just try.
I just want to start with saying I already searched this forum for similar problems like mine but I'm just not that technical and don't know every correct term used to describe the printerparts, meaning I'm never sure if another ones problem is related to mine.
My issue:
Recently my printer (Ultimaker²) makes these weird noises when it's printing the first layer. The noises are comming from the feeder wheel (or is it also called extruder, maybe stepper motor, driver? ).
Every time I hear the noise, which is a short knocking sound, I see the wheel turning back. I'm not sure if this is related but when I watch my print at the same time while it turned back, I notice the print is messed up at that part, I mean there is no filament, no infill, a 'missing line'.
But when the first layer is done and the fans start to work everything is normal again. It prints perfectly and the noises are gone. The toplayer is always perfect too by the way.
My stats:
Layer height: 0.1mm
Shell thickness: 0.8mm
Bottom/top Thickness: 0.6mm
Fill Density: 20%
Print Speed: 50mm/s
Nozzle Size: 0.4
Initial Layer Thickness: 0.3mm
Buildplate temperature: 60°C
Head Temperature: 210°C
Printed with PLA (3mm +/- 0.1mm)
Thank you in advance.
Maybe I will try to add some photos later on, the print is still busy while I'm writing this.
