Your hot end is way too close. If you’re using standard quickprint settings, then your skirt should be 0.425mm thick (I only use HIPS and ABS so if it’s different for PLA, someone please correct me). Go up to “Machine” in the toolbar and select “Machine Settings”. Look for the row that says “Z offset” and put in 0.2.
Print a new part with a skirt. When finished, remove the skirt, and using a pair of calipers, measure the thickness. If the thickness of the printed skirt measures, say, 0.22mm, and you know the initial layer thickness should be 0.425mm, then the difference is 0.425- 0.22mm - = 0.205mm.
Now go back to the Z offset and add 0.205 to your previous offset of 0.2, so Z offset should now be 0.405. Print a new part, measure the skirt…if it’s not really really close to 0.425, repeat the previous steps until you hone in on it. Then you should be able to leave that setting alone for the most part for the foreseeable future, unless you have problems with parts sticking to the bed etc. But that’s another issue you don’t need to worry about quite yet.
