Anycubic test tower

This specialized calibration test is the key to unlocking the full speed potential of your Anycubic printer, from the Kobra series to the latest high-speed models. Its smooth, serpentine design acts as a "stress test" for your extruder, gradually pushing the volumetric flow rate (mm³/s) to the very edge of your hardware's capabilities. The visual color gradient in the slicer pinpoint precisely where your hotend struggles to melt filament, helping you avoid dreaded underextrusion before it even starts. It is an essential tool for any maker looking to slash print times while maintaining the strength and surface quality Anycubic machines are known for. By running this test, you transform guesswork into a finely-tuned profile, turning your printer into a fast and reliable workhorse.
