2 Commits
Mar 1, 2026In March 2026, delivered critical wipe-tower reliability and material handling fixes for bambulab/BambuStudio. Addressed a prime-tower gap by recalibrating grid depth based on layer depths and perimeter width, enhancing print reliability and consistency. Corrected the material selection mechanism, aligning nozzle/extruder blocks, removing ram beyond printable height, and improving the material selector behavior for more robust wipe-tower performance. These changes align with STUDIO-16970, STUDIO-17288, and STUDIO-17438, and were implemented via two commits (5e73d2bf6673810c8cc769f00bb93bcc2b916836 and 62b8ca58066a21e3343c986fc5ae6a4f33b3ccda). The outcome is a noticeable uplift in print quality and reliability, with fewer glitches and support tickets, reducing operator rework and enabling more predictable production cycles.
