Quick Calibration tool (0.2mm)

This is a small and very quick calibration tool for 0.2 profiles.Use it to determine the quality of layers, walls, tolerances, bridging, threads, and more. See the supplied images (and the text below) for a quick guide to what to check for.Based on your findings, here are some general tips to get you started. Please note: While these tips should help, they are not the be 'all end all' of troubleshooting. I'm no expert, but have done my best to help as much as I can.First layer issuesAchieving a perfect first layer requires a precise balance between the Z-offset and bed conditions.If you see gaps between lines or round, spaghetti-like strands, your nozzle is too high and "dropping" the filament; you must decrease the Z-offset in small increments to press the plastic into the bed.Conversely, if lines are transparent and paper-thin - or if the extruder makes a "clicking" sound - the nozzle is too low and choking the flow.If the surface shows ripples or waves,you are slightly too low, as the excess plastic has nowhere to go but up, creating ridges that require you to back off the nozzle height.When a layer looks good initially but peels at the corners, you are likely dealing with surface contamination or thermal contraction. While Isopropyl Alcohol is common, washing your build plate with warm water and dish soap is often more effective because it physically breaks down and removes oils rather than just spreading them around. You can further improve grip by slowing your First Layer Speed to 15–25 mm/s and increasing the First Layer Line Width to 120–140% to create a wider footprint. Using a slightly thicker First Layer Height (e.g., 0.24mm) also helps by making the print more forgiving of minor bed height inconsistencies.Thermal settings must be tailored to your specific material. For PLA, a bed temperature of 55–65°C is ideal with the cooling fan disabled for the first few layers. PETG requires a hotter bed of 70–85°C and prefers a "laid" layer rather than a "squished"
