K-Factor Calibration Pattern
Notes on the settings:
- Fast and slow speed should be significantly different or the K-Factor effect will barely be visible
- Use bed levelling requires a probe
- The printer's bed is assumed to be rectangular. For round beds use the diameter as approximation but extra care should be taken that the pattern size matches the bed. The overall width (X-direction) of the print is always 100 mm. The length (Y-direction) depends on the K-Factor Settings. The sanity check will only work for rectangular beds.
- Start and End value for the K-Factor determines the range that the test pattern will cover. For example a start value of 50 and an end value of 150 will test a range of 100.
- The K-Factor stepping determines how many test lines are printed for the above range. For example, a Stepping of 10 and a range of 100 results in 10 test lines. A stepping of 3 would not work in this example as 100 cannot be exactly divided by 3. The script will throw an error message if an exact division is not possible. In this case either the range or the stepping needs to be adjusted.
- The proper K-Factor depends on the filament, nozzle size, nozzle geometry and printing temperature. If any of these values change, the calibration might need to be repeated.
