Upgrade part:

1. The officially upgraded profile frame is fixed by the triangular fixing block, instead of the original screw fixing method. On this basis, we have added threaded fastening to prevent the profile from shifting, and the frame structure is more firm and stable;

2. The clamp of the fixed bearing of the hot bed support frame is replaced by a printed part, which is easier to install than before;

3. Upgraded Bear extruder and X-axis designed to improve print quality, reliability and ease of maintenance
