Lower friction between the two pulley gears.Increase the grabbing force on the filament.If you have had a clog, they can also have collected residue grinding the filament which will, in turn, reduce their grabbing force on the filament. The other is the idler gear, which spins freely mounted on the idler door. One is the pulley gear, secured on the extruder's motor shaft by a set screw. The MK2.5/S and MK3/S/+ printers are equipped with two Bondtech gears, made of hardened carbon steel. Clear away any debris that may be stuck and check that it can rotate freely. Hold the propeller of the fan to prevent it from spinning while cleaning it with canned air. Tweezers can be used to take out any plastic strands. Dust or plastic build-up can decrease their efficiency or even damage them.Ī cotton swab can also be used to clean off dust and debris from the propeller or canned air will clear the dust. However, that does not mean you should not check them during maintenance. The Original Prusa i3 MK3/S/+ can spot if any of the fans stop spinning. You can find more information on how to take care of your flexible steel sheet in this article. In this case, please remove the bearings from the printer and lubricate them from the inside with a pea-sized amount of lubricant.Īll flexible steel sheets should be cleaned regularly to ensure adhesion, but the exact methods and washing solutions can differ depending on your type of sheet. Despite cleaning and lubricating the smooth rods, it can happen that the axes' movement is still not smooth. Bearings: Clean and lubricate the bearings and rods as shown this guide.If you notice any scratch, verify it with your fingernail. Smooth rods: scratches/grooves - take each rod between two/three fingers and move them slowly from one end of the rod to another, while rotating the fingers around the rod.Alternative: You can use the acupuncture needle that comes with the printer or a toothpick. If you don't have a brass brush any brush with hard bristles will do the job. Brush: a small brass brush is an ideal tool for cleaning the Bondtech filament pulleys.Be sure to not hold it upside down while spraying - otherwise, you could damage any electronic components while trying to clean them.
