Velleman DEM401 Problems and Solutions
The Velleman DEM401 is a popular 3D printer, but it can be prone to some common issues. Here are some of the most common problems and solutions, as provided by experts:
Problem: The printer is not extruding filament. Solution:
- Check that the filament is properly loaded into the printer.
- Make sure that the filament is not tangled or broken.

- Level the build plate. If the build plate is not level, the prints will not stick properly.
Problem: The prints are not coming out smooth. Solution:
- Check the print settings. Make sure that the layer height, print speed, and temperature are correct for the type of filament you are using.
- Increase the number of perimeters. This will help to create a smoother print.
- Use a finer layer height. This will also help to create a smoother print.
Problem: The printer is making strange noises. Solution:
- Check the fans. If the fans are not working properly, they can make strange noises.
- Check the belts. If the belts are loose, they can make strange noises.
