3d Printer Belt Tension Too High

This will get you to the point where the belt doesnt skip and isnt too tight.

3d printer belt tension too high. Not so much the weight as maybe trying to set tension too high. Posted in 3d printer hacks tagged 3d printed 3d printer belt clamp belt driven fail failure gt2 ummd. If the tension becomes too loose the belt may slip on top of the drive pulley which means the pulley is rotating but the belt is not moving. An overtightened belt can create excess friction in the bearings that will prevent the motors from spinning.

If the belt was originally installed too tight this can also cause issues. Dont apply too much force just as much as you would expect the motor to create. With the print head in its home position you can place a ruler upright to see the height of the belt in its resting state. Then tighten the belt by one tooth and check again if the belt skips.

The best way to fix a 3d printer printing too thin is to increase the temperature of your nozzle so that the filament has more of a liquid consistency allowing easy extrusion through the nozzle. The main problem is that the model im building is a rostock max so the belts have about 1 meter high 32808 ft and despite i really squeeze it tight before put the belt in the bearings i use bridle to join the two parts of the belt as you. You can also try increase the flow rate in your slicer settings especially if this happens after using a different material. We use fiberglass core and aramid core timing belts in 3d printers for a reason because theyre as stiff as possible in tension.

Spring tensioners makes the belt more stretchy. Im building a 3d printer here at fab lab leon spain and i have to adjust the tension of the belts. You can see the problem that can occur if the material is squeezed and deformed. Youre printing material has tolerances set for how wide it can be usually in the 002mm range for 175mm filament.

Of course this method will get you to the lower limit of optimal belt tension so maybe a little bit more tension wont hurt but at least it provides a reasonable starting point. If your printers spring tension is too high the wheel will grip your material with too much force and cause it to deform and change shape.
