So, I'm pretty new to 3D Printing, and to quote Spock from Wrath of Khan I would say "He is intelligent, but not experienced". Now everything I have been reading about Z-offset seems to talk about a 0.2 mm gap and using a piece of paper.
Wishing to be accurate, I have tried to use my 0.2 mm feeler gauges and this is too high.
However, the thickness of paper depends on the GSM (grams per square metre). A Google search tells me that the average thickness of paper is ~0.1 mm but how can we be accurate with this variation.
I tried using a 0.1 mm feeler gauge and even this seemed too high. Is this because of the lack of give in the metal? Anyway, I have now settled for a Lotto slip (UK Lottery) which has a thickness of 0.1 mm and seems to allow me to set a good offset.
However, I would welcome someone who can explain the science behind this.
