First Layer Calibration Prusa MINI

Thank you to GKMAKEIT for the original. I found this so helpful at getting the perfect first layer setup that I found myself using for all different types of materials - So, here it is.

See the original author's video below, or follow this step by step guide:

1. Clean your build plate and set the sheet your are using in the firmware
2. Run the print GCODE and set a Z-offset that is at least above the bed, not gouging it
3. As the printer extrudes the skirt, get the Live-Z down so at least the material is sticking to the bed. While printing perimeter, just get a decent line. Don't worry about gaps.
4. Give it about 10 passes on each Z-offset, then adjust down or up accordingly. I Use 0.05mm then 0.025mm adjustments typically.
5. I Suggest writing the live Z for each section on the side with a sharpie so you can refer back to the print.
