The Y-Axis Belt Tensioner of the JGAURORA A5 can now be adjusted from outside without having to unscrew the housing. On the right side of the printer, a 3mm threaded rod is visible. This rod fits loosely through the stop in the inner space to the tensioner. The stop is secured with a Y-axis. Now, on the threaded rod, a nut is tightened against the stop. The more I tighten the nut on the threaded rod, the tighter the Y-axis becomes. I don't know if this construction will last forever. If someone makes the effort to replicate this tensioner, they must make sure that the triangular holding plates are installed in the correct position because the hole spacings are not equal. I have labeled them and the position marked "R" is the idler roll. The position marked "O" is at the top. Printer - Anet AM8 Material - PLA Nozzle - 0.5mm Layer height - 0.3mm Screws = M3 with nut Threaded rod - M3 Initially, I chose PLA as material but will switch to PETG if problems occur. I think PLA is sufficient because my print plate is isolated at the bottom and the room below it does not get warmer than about 30°C. No space was lost in the Y-axis due to the installation of the tensioner. The first test ran flawlessly. https://www.youtube.com/watch?v=U4jvFlZqkZY&t=13s Best regards, Hubert
