Z-Axis during Print

Hi Guys,I've got an Ender 3 S1 Plus, and have an issue which I don't know how to fix.Printing small height items is generally Okay, however I am currently at a height of 65mm on a current print, and I've had to adjust the Z-Axis several times now to +1.75mm from when I started as I keep hearing the nozzle scrape against the infill.During the print as soon as I hear the nozzle scrape against the infill, I'mm insrease the Z-Axis by 0.05 or 0.10mm and it will be fine for a couple of layers then I will have to do it again. If I do a small print of say no more than 10mm heigh all is fine no adjustments needed, but this is the second time going high, and it appears the higher I go, the more adjusting on the Z Axis is needed, everything else is excellent, with no issues, does anyone know how I can remedy this one issue?
