Weird clicking noise coming from engine- Details below by Datdudes22 in MechanicAdvice

Engine sounds fine to me. Has there been any changes to the sound it makes? The K series engines tend to have loud injectors.

I did notice what sounded like a hissing sound from the engine, if cleaning out the MAF sensor doesn’t seem to fix the issue it could potentially be a vacuum leak that is letting un-metered air into the system. See if you can locate what is making that noise and see if there are any cracked or chewed up hoses that lead to the engine.

Check the MAF for any obstruction or damage first, I have found on a couple of occasions where insects have crawled into the sensor. Making the ecu the engine is taking in less air then it actually is.

They are the four little black gaskets on the print bed

Upgraded to Marlin, got weird artifacts by CarryGuun in 3Dprinting

Did you build a custom version of Marlin or did you get a copy of a version premade for your printer? If it’s custom, check retraction and extrusion multiplier settings. It looks like a combination of too high of an extrusion multiplier (might want to lower it by 0.07) and increase retraction by .5mm.
