The first layer of a print is unquestionably the most important. In order for your print to be successful, the first layer must properly anchor the part to the bed so that it does not warp. The first layer adhesion also affects how easily the part will be removed from the build platform when the print is completed.
To learn what a good first layer looks like, and to practice printing them, we provide two example G-code files, as well as their corresponding factory files for you to use. Each file will simply print a single-layer rectangle shape, giving you time to make small adjustments to the Z offset from the user interface. These should be used to practice fine-tuning the calibration of the Z offset of each tool while printing. You must complete the Z Calibration process found in the Calibration section before printing.
|t0_z-calibration.gcode||Left Tool Calibration||Use with ABS for T0|
|t1_z-calibration.gcode||Right Tool Calibration||Use with ABS for T1|
|z-calibration.factory||Base Factory File||Modify to suit your needs and material choice|
A typical process would be as follows:
T1using its respective calibration file.
In order to get a feel for what would be considered a good offset for producing a good print, please refer to the following set of images, which show prints with offsets that are too small (bed too close), too big (bed too far), and just right.
