First Layer Test .25 Layer Height

This calibration takes into account all your printer profile's first layer settings, giving a perfect Z-Offset. Use an opaque filament.

1. Use your printer's initial calibration feature if you have any
2. Print “Z-Offset Calibration.stl” and let it cool. (use the tab at the top to lever it off the bed)
3. Examine the print:
   • If the lines are not joined, lower the Z-Offset (Too High)
   • If the surface is rough, raise the  Z-Offset (Too Low)
   • If the print is see-through, raise the Z-Offset (Much Too Low)
4. Repeat until the lines of the print are joined and smooth.

If you are really anal like me, you can use a set of calipers to make sure the print is 0.25 mm. If you get to 0.25 mm and the lines aren't joined, then increase your first layer flow. Repeat until the lines of the print are joined and smooth.

Good Luck, and Happy Printing!
