Approprié NC-UV0609PEIII-II Y-axis small belt replacement​ is required when the print bed moves jerkily, montre la bande dans la direction Y, ou la ceinture semble usée, étiré, ou fissuré. La petite courroie de l'axe Y transfère le mouvement du moteur d'entraînement au chariot à plat. A degraded belt causes misregistration, positioning drift, and print defects. Le remplacer restaure la précision, smooth bed movement. Suivez attentivement les étapes ci-dessous.

Préparation

Éteignez l'imprimante et débranchez le câble secteur. Portez des gants antistatiques. Dégager l’espace de travail et assurer un bon éclairage. Vous aurez besoin: a new compatible Y-axis small belt (longueur et profil de dent corrects), jeu de clés hexagonales (2.0 mm, 2.5 mm, 3 mm), Tournevis cruciforme, and a tension gauge or ruler for deflection measurement.

Retrait de l'ancienne courroie

Open the side or rear access panel covering the Y-axis drive assembly. Manually slide the flatbed to the center or home position. Loosen the tensioner nuts to release belt tension. Disengage the belt from the drive pulley and the idler pulley. If the belt ends are fixed by clamps or screws, remove those fasteners and slide the old belt out of its guide path. Inspect pulleys for debris or damage.

Installation de la nouvelle courroie

Route the new belt over the drive pulley and idler pulley, suivre le chemin d'origine. If the belt uses metal end clips or clamps, secure them into the mounting brackets on both ends. Pull the belt taut by hand to remove slack. Engage the tensioner and tighten the adjusting nuts until the belt deflection measures 5–8 mm under moderate finger pressure at the midpoint between pulleys. Serrez tous les contre-écrous.

Tests et étalonnage

Rebranchez l'alimentation et allumez l'imprimante. Jog the flatbed forward and backward from the control panel. The motion should be smooth and quiet. Run the auto-homing routine. Print a test pattern with fine vertical lines to verify Y-axis registration. If banding persists, revérifier la tension de la courroie et l'alignement des poulies. Once motion is stable and prints are aligned, le NC-UV0609PEIII-II​ est prêt pour la production.

Vérifications post-remplacement

Operate the machine for one hour and re-check belt tension. Inspect belt tracking—ensure it rides centered on pulleys without rubbing. Periodically clean pulleys with a dry cloth. Replace the opposite-side belt if both show similar wear, to avoid uneven tension.
