Online STL-to-G-code slicers make 3D printing faster and more accessible by eliminating heavy software installations and enabling browser-based workflows. However, issues like slow uploads, failed model loading, scaling errors, poor support generation, and stalled slicing can disrupt productivity. Many of these problems stem from mesh errors, overly detailed models, unit mismatches, or incorrect printer profiles. G-code issues, visual artifacts, and limited material or printer support are also common challenges. By simplifying geometry, repairing STL files, verifying units, selecting accurate printer profiles, and reviewing previews, users can avoid most issues and keep online slicing workflows efficient, secure, and reliable.
