Quick Calibration test

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. 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 issues**

Achieving 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,
