I have a quick question on an issue. I’ve updated my firmware as normal but my print looks fine just I hear a grinding noise time to time and it seems in certain areas of the print the layers are higher than others. I ran my hand slightly over the infill and it has a light wavy feel with some layers higher or lower than others making me think at points the nozzle is hitting the higher layers. Has anyone ever come across this? You can’t really see from the image but wanted to ask so I don’t waste time or materials on a 400+ hour print. Thank you in advance on any information you can help me with.
