Dankdryer improvements: Difference between revisions
Created page with "In an earlier article, I designed and constructed a high-temperature filament dryer. Before I was even done putting together the first design, I was thinking of improvements for reliability, efficiency, cost, and ease of assembly. I've put some of them into effect, and the result is most pleasing. ==Models== Rather than mounting the RC522 directly onto the bottom of the top chamber, we print a short mount for it (building the mount into the h..." |

The n-FET goes on the ground side of the motor, and the diode runs in parallel with the load (i.e. is connected to the motor's two pins). This eliminates five wires (ten soldering points). | ||
