Using the LDO Orbiter V2.5 Extruder is easy. Just install it properly on your 3D printer following the standard installation steps. When you're ready to print, feed the filament through the gears and start your print job. To keep it working well, regularly check the RNC coated gears for any signs of wear. If you notice the filament feeding isn't as smooth as before, it might be time to clean the gears gently. Also, make sure the knurled Spinder Shaft is clean and free from debris. Don't force the filament through too hard, as it could damage the gears. With proper use and maintenance, this extruder will serve you for a long time and give you great print results.
