Printer tests for deltas

thingiverse

This set of basic tests evaluates the fundamental mechanics of your printer. Each test aims to be independent from slicer settings and isolates a single aspect of printer performance. XYZ size: Measure the print dimensions along the X, Y, and Z axes. Changes in these sizes are directly related to miscalibrated arm lengths. This test measures each dimension externally as an object's size or internally as a void's size, eliminating over/under extrusion effects. Gap test: Prints square blocks within rectangular holes with decreasing gaps on two sides. This test determines the minimum gap required for straight walls to prevent fusing; surprisingly, even a 0.1 mm gap can cause fusing on some printers. Tilted-gap test: Similar to the previous test but with sloping gaps (overhangs). This type of gap occurs in herringbone gears and requires more significant gaps to prevent fusing. This test is still a work in progress, being more challenging than the others. Corner-cutting tests: Printers often produce undersized circular holes due to filament's tendency to cut corners. This test provides positive and negative corners at various angles, 10 mm apart, for you to measure and assess the severity of this issue. The corners are located between long straight sides, minimizing path simplification effects.
