Why is my 3D printer dragging filament?

Why is my 3D printer dragging filament?

It may be too high pushing more filament than it should. To correct this, you need to do the length test where you will extrude 10mm or 50mm and measure the string of plastic. There might be some stretch so a 10mm may measure as 11mm but as long as your close it should be good.

What causes stringy filaments?

A common cause of persistent PLA stringing, or other materials; is a print temperature that is too high. When the temperature in the print head is too high for the material being used, the filament becomes too viscous and watery and leaks out the print nozzle.

Can filament get old?

However, when you store your PLA filament in an exposed environment, its expiry date may range from one month to two years. As a result, when exposed to moisture through the air or water, PLA filament can go bad. Water or moisture can make PLA filament or any other to swell up. As a result, it can jam the extruders.

What causes printer filament to stick to nozzle?

In some cases, the problem of filament sticking to the nozzle manifests in the form of the filament “curling” towards the nozzle. This is no longer a matter of bed adhesion – the filament might not even come in contact with the print bed! When filament curling happens, it is almost certainly a sign of a clogged nozzle.

Why is my Prusa print nozzle dragging and smearing filament?

It clearly seems like you are extruding too much plastic. I use slic3r myself with repetier so I am familiar with the settings. All the values should be 0 except first layer sometimes is 100%-200% depending on your personal setup. Increasing these values may cause more filament to leave the extruder.

Why is my nozzle dragging across all of my prints?

I’m finding that my nozzle is dragging across the top surface of every full layer, and leaving drag marks along the finished surfaces. Finished surfaces are also too rough. Is this an extrusion issue or Lift-Z issue?

How is the nozzle on a 3D printer supposed to be?

This really depends on your nozzle diameter and layer height but generally, your printer’s nozzle should be around 0.2mm away from your print bed, while your bed leveling screws are fairly tightened. The most common method to determine the distance between the nozzle and the bed is using a piece of paper or thin card between the nozzle.
