All things mentioned are worth trying. I’ve had prints that have a rough start due to overextrusion never smooth out and it wouldn’t shock me that a strongly overextruded first layer would be having an effect on the 10th layer – I’ve personally made pieces that look like garbage several centimeters up from the base.
Also when looking at your pictures, it looks like there is almost a brim attached to the first layer it is so squished down and wide – I bet if you look at your Z height, filament diameter, flow rate percentage, initial layer width percentage, and initial layer height, you’ll find a way to take away the blemish.
For example, if your nozzle is too close to the bed and you’re printing with settings of a 0.425 initial thickness, with 125% line width, 2.85 mm diameter filament and 100% flow rate, if your filament is really 2.98 mm diameter you will be pumping more filament in reality than the printer thinks it is pushing, and it will have to spread out and bunch up because the nozzle is closer to the bed than it should be and the plastic doesn’t have anywhere to go. I could totally see it taking a few layers to get past a rough start like that.
Also, if you can see any visible deflection of any of the washers during probing, stop the print, clean the nozzle and washers, and start over because your Z height is going to be too low. If you are having trouble with deflection, try jrhubott’s firmware – it probes much more reliably than stock.
