Plotter Kh-720: Cutting
The KH-720 is not a flawless machine. It lacks closed-loop motors, has no built-in contour camera (only a line sensor), and its plastic blade holder wears faster than brass alternatives. However, for the price, it delivers and a surprisingly robust optical registration system.
Cuts are complete in some spots but not others. Fix: Your cutting strip (the plastic strip under the blade) is worn out. Rotate it to a fresh section or replace it. Also, check if the pinch roller pressure is uneven. cutting plotter kh-720

The KH-720 is a cutting-edge plotter that boasts a robust design, advanced technology, and user-friendly interface. Its primary function is to accurately cut a wide range of materials, including vinyl, paper, film, and other thin materials. The plotter is widely used in various industries, such as sign making, graphics, and packaging.
The KH-720 taught him patience. It enforced limits: long curves needed slow passes, intricate lettering required careful weeding, and sometimes the material resisted with a stubborn crease. The machine gave him another lesson—about choice. With each cut he made decisions: where to start a line, how deep to set the blade, whether to add a border. Small, precise acts that accumulated into things others could hold.
