HexCalibr tunes a printer that already works. When a print fails for a reason no calibration can fix (a clog, a loose belt, a faulty thermistor), these resources help you find the cause first.

More
- You start from what you see on the print (stringing, warping, layer shifts, gaps, elephant foot) and it points you to the chapters with causes and fixes, including hardware faults such as heaters, thermistors, stepper motors and clogs. It also covers maintenance, electrical safety and materials.
- BeginnerRead it when something is clearly broken, before calibrating: a test cannot be read on a printer with a partial clog or a loose belt.
- ExpertIt was written for 2021–2022 printers and its slicer examples use Cura. Use it for diagnosis; for the settings, follow the PrusaSlicer names in these guides.
- In this suite, its chapters on stringy or blobby prints and poor layer adhesion go with the temperature tower; over and under extrusion, gaps and elephant foot go with the first-layer and flow tests.
