As you can see, the Velleman DEM100 is a very affordable option for a microcontroller. It is comparable to the Arduino Uno in terms of price, processor, and RAM. However, the Velleman DEM100 does not have as much flash memory as the Arduino Uno. The Raspberry Pi 3 Model B+ is a more powerful option than the Velleman DEM100. It has more RAM, flash memory, and I/O pins. It also has more connectivity options and can run a wider variety of operating systems. However, the Raspberry Pi 3 Model B+ is also more expensive than the Velleman DEM100.

Ultimately, the best microcontroller for you will depend on your needs and budget. If you are looking for an affordable option for basic projects, the Velleman DEM100 is a great choice. If you need a more powerful microcontroller for more complex projects, the Raspberry Pi 3 Model B+ is a better option.

Velleman DEM100 Problems and Solutions

The Velleman DEM100 is a popular 3D printer, but it can experience some common issues. Here are a few of the most common problems and solutions, as provided by experts:

The printer is not extruding filament. This can be caused by a number of things, including a clogged nozzle, a faulty extruder, or a lack of filament. To fix this, try the following:
- 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 for any problems. If the extruder is faulty, you may need to replace it.
- Make sure that there is enough filament in the spool. If the filament is low, you may need to load more filament into the printer.
The prints are not sticking to the build plate. This can be caused by a number of things, including a dirty build plate, a low bed temperature, or a lack of adhesion. To fix this, try the following:
- Clean the build plate with isopropyl alcohol.
- Increase the bed temperature.
- Use a glue stick or hairspray to improve adhesion.
The prints are not coming out smooth. This can be caused by a number of things, including a low print speed, a low layer height, or a poor quality filament. To fix this, try the following:
- Increase the print speed.
- Increase the layer height.
- Use a higher quality filament.

If you are still having problems with your Velleman DEM100, you can contact Velleman customer support for further assistance.

Here are some additional tips for troubleshooting common Velleman DEM100 problems:

Check the printer settings. Make sure that the printer settings are correct for the type of filament you are using.
Calibrate the printer. Calibrating the printer can help to improve the accuracy of the prints.
Use a slicer program. A slicer program can help to improve the quality of the prints by generating the G-code that the printer uses to print the object.
Be patient. 3D printing can be a time-consuming process. It is important to be patient and allow the printer to complete the print without interruption.
