+ | ==== 5. Adjust the initial layer height ====ย | ||
+ | Regardless of whether you're printing with a coarse or fine layer height, you want the **initial layer height of the initial layer to be set between 0.1mm to 0.15mm**. This is because the ratio of nozzle diameter to first layer height needs to be 3:1 or 4:1 to help material be properly squished onto the bed.ย | ||

+ | If the print is still not sticking, try loosening all four levelling thumb screws by 1/8th of a turn, and try again. This will reduce the first layer height very slightly. Repeat this until the print starts to stick well. | ||
