Velleman DEM401 Problems and Solutions
The Velleman DEM401 is a popular 3D printer, but it can be prone to some common problems. Here are some of the most common issues and solutions, as explained by experts:
- The print head is not extruding filament. This can be caused by a number of things, such as a clogged nozzle, a faulty extruder gear, or a problem with the filament itself. To fix this, try the following steps:
- Check the nozzle for any blockages. If the nozzle is clogged, you can try heating it up and using a needle to clear the blockage.
- Check the extruder gear for any damage. If the extruder gear is damaged, you will need to replace it.
- Make sure that the filament is properly inserted into the extruder. If the filament is not inserted properly, it will not be able to extrude.
- The print is not sticking to the build plate. This can be caused by a number of things, such as a dirty build plate, a low bed temperature, or a lack of adhesion. To fix this, try the following steps:
- Clean the build plate with rubbing alcohol or isopropyl alcohol.
- Increase the bed temperature. The recommended bed temperature for the Velleman DEM401 is 60 degrees Celsius.
- Use a glue stick or hairspray to improve adhesion.
- The print is not coming out smooth. This can be caused by a number of things, such as a low print speed, a low layer height, or a problem with the slicer settings. To fix this, try the following steps:
- Increase the print speed. The recommended print speed for the Velleman DEM401 is 50 millimeters per second.
- Increase the layer height. The recommended layer height for the Velleman DEM401 is 0.1 millimeters.
- Adjust the slicer settings. There are a number of different slicer settings that can affect the quality of the print. Experiment with different settings to find what works best for you.
