When to under extrusion after a layer change?
Right now I think it’s pausing at the layer change, over extruding, then underextruding as it speeds back up. Thinner layers should help (such that the nozzle pressure is lower). Also look at the “spiralize outer contour” feature which doesn’t need to change layers.
Why does plastic have a hard time exiting the extruder?
For example, if you are trying to print at an extremely low layer height, such as 0.01mm, there is very little room for the plastic to exit the nozzle. This gap below the nozzle is only 0.01mm tall, which means that the plastic may have a difficult time exiting the extruder.
Where do I find the extrusion width in simplify3d?
Another setting to check within Simplify3D is the extrusion width that you have specified for your extruder. You can find this setting by clicking “Edit Process Settings” and going to the Extruder tab.
What to do if your extruder filament is not working?
If you think your filament may be at fault, try swapping the spool for a new, unopened, high-quality spool to see if the problem goes away. If you have verified everything above and are still having problems with inconsistent extrusion, then you may want to check for mechanical issues with your extruder.
Why do I get under extrusion on my Ultimaker?
These settings define the flow rate, which is the volume of material that is extruded per second. If you want to push through more material than your Ultimaker is capable of, this will lead to under-extrusion. There should always be a good balance between the temperature and speed.
Why is my under extrusion not working properly?
Another reason can be the absorption of too much moisture by the filament. Some materials (especially PVA) are very sensitive to moisture and can lose quality when used or stored in a humid environment for too long. Correct handling and storage of the material are very important in this case.
How can I tell if my print is under extrusion?
The first and easiest things to check if your print is suffering from under-extrusion are the material settings. It’s important that the material profile on your Ultimaker (or material settings in Cura) matches the material. For example, a temperature setting that’s either too high or too low can lead to problems.
