3D printer first layer calibration process
This is a 3 x 3 inch square used to help calibrate that oh so important first layer. This seems to be one of the most problematic asked about questions with new people to the 3d printer community.
If you are using a Prusa MK3
First tell the firmware which sheet you have mounted (smooth or textured) the last Z setting you set will be stored by the firmware for that sheet.
You need to repeat this process for each different sheet type you use. The physical thickness of the textured sheet is thinner than the smooth sheet.
Never ever mislead the firmware about which sheet is current. That can dig trenches across the sheet - or print in the air.
