Cooling Threshold Calibration

thingiverse

Printing thin objects fast can prevent the filament from cooling properly between layers, resulting in warping. To calibrate my printer's filament cooling times, I print these blocks to ensure a solid top-to-bottom finish. To test your printer's calibration, follow these steps: Print the blocks and measure their thickness with calipers to gauge the amount of warping occurring. There are three 5mm x 5mm blocks in this file, each with different heights: 10mm, 15mm, and 20mm. If your print is warped or sagging, try slowing down the minimum print speed in Slic3r under Filament Settings. Go to Cooling Thresholds, adjust as needed, then re-print.
