CR M4 Cura Profile & Tips for Using Cura Slicer and Creality Slicer

Creality’s latest addition to their 3D printer lineup, the CR-M4, boasts a large build volume of 450 x 450 x 470mm, making it an ideal workhorse for creating large models with minimal or no post-processing. Additionally, it allows you to batch-print multiple parts simultaneously, enabling you to maximize your creativity and unleash your imagination.

Although Cura may not yet have a slicing profile ready for this new printer, you can still start printing with it using Creality Slicer V4.82-279 (latest at the moment) and above, which can be downloaded from their official website. This software comes with a pre-loaded profile that is optimized for the CR-M4, allowing you to get started with your printing projects right away. Below is the guide for CR-M4 Cura Profile

However, if you prefer to use Cura slicer instead, you can still achieve excellent results by copying the settings from Creality Slicer, as well as the start and end G-code. This will ensure that your prints are executed according to the Creality recommended setup, without any issues or errors.

Retraction Setting

The CR-M4 is equipped with a direct drive spire extruder and bi-metal heat break, requiring shorter retraction settings to prevent clogging and minimize stringing for optimal performance.

Default Retraction Distance: 0.8mm
Default Retraction Speed: 40mm/s

If you are still getting stringing issue, do print out the retraction tower by TeachingTech to test your best performance. distance range from 0.5 to 3mm, speed from 30-60mm/s
