How can you tell if a filament is bad?

How to Tell If PLA Filament Has Gone Bad? Moisture absorbed PLA filament will present with certain features that will tell you immediately that something is wrong. 3D printer damage, weaker 3D prints, and poor 3D print quality are the three main features of an expired PLA filament.

Why is my printer making a grinding noise?

If your printer is making a grinding noise, you may have a loose gear or roller in the printer. If the noises started shortly after you installed a toner cartridge, turn off the printer and pull out this toner cartridge. Look up into the printer where this toner went. Remove the toner cartridge from your printer.

Why is my printer making a ratcheting noise?

A grinding sound is heard when the printer is turned on or when it is printing. Blinking lights may accompany the noise. The problem can be caused by a carriage stall or a paper jam.

Why does my extruder grind up my filament?

The reason your extruder is grinding up your filament can be due to reasons such as bad retraction settings, low temperature & underextrusion issues, damaged PTFE tubing, the feeder tension being too strong or a combination of a number of reasons. Depending on what the cause is, there will be a solution.

What to do if your printer filament is grinding?

If it’s too tight, slightly loosen your extruder’s feeder (gear part) grip on the filament. Replace the PTFE tube: If your Bowden tube or hot end lining (often a PTFE tube) are compromising filament movement, you may need to replacing it. In any case, make sure it’s not bend or twisted.

What should the temperature be for grinding filament?

If you continue to encounter filament grinding, try to increase the extruder temperature by 5-10 degrees so that the plastic flows easier. You can do this by clicking “Edit Process Settings” and selecting the Temperature tab. Select your extruder from the list on the left and then double-click on the temperature setpoint you wish to change.

Why does filament keep grinding on the Bowden ID?

Furthermore filament that has not been wound cleanly onto the spool will have slight kinks of tighter diameter, which in turn increase the “normal force” and hence dry friction on the Bowden Id.
