Nettet28. des. 2024 · Description: When using Linear Advance, since version 1.1.7 Marlin produces blobs at almost every 90° corner. Expected behaviour: No blobs are generated, as on 1.1.6. Actual behaviour: When printing objects like the 20x20 XYZ calibration cube or the Linear Advance test pattern, Marlin produces large blobs at avery 90° corner. Nettet19. mar. 2024 · @thinkyhead My multiplier is set correctly in S3D, I have calibrated the flow rate to be correct. @comps the LA calibration pattern is not using UBL that is why the numbers on the right side failed.
